When the drive is powered up, the power components and some of the control components are 

connected to the line supply. It is extremely dangerous to touch them. The drive cover must be kept 

closed. 

CAUTION 

locking system is not sufficient: fit a cut-off on the power circuit. 

After the ALTIVAR has been switched off and the green LED has gone out, wait for 3 to 10 minutes before 

working on the equipment. This is the time required for the capacitors to discharge. 

The motor can be stopped during operation by inhibiting run commands or the speed reference while the 

drive remains powered up. If personnel safety requires prevention of sudden restarts, this electronic 

ENGLISH 

The drive is fitted with safety devices which, in the event of a fault, can shut down the drive and 

consequently the motor. The motor itself may be stopped by a mechanical blockage. Finally, voltage 

variations, especially line supply failures, can also cause shutdowns. 

NOTE 

If the cause of the shutdown disappears, there is a risk of restarting which may endanger certain 

machines or installations, especially those which must conform to safety regulations. 

In this case the user must take precautions against the possibility of restarts, in particular by using a low 

speed detector to cut off power to the drive if the motor performs an unprogrammed shutdown. 

Equipment should be designed in accordance with the specifications laid down in the IEC standards. 

As a rule, the drive power supply must be disconnected before any operation on either the electrical or 

mechanical parts of the installation or machine. 

The products and equipment described in this document may be changed or modified at any time, either 

from a technical point of view or in the way they are operated. Their description can in no way be 

considered contractual. 

The Altivar 38 must be considered as a component: it is neither a machine nor a device ready for use in 

accordance with European directives (machinery directive and electromagnetic compatibility directive). 

It is the responsibility of the end user to ensure that the machine meets these standards. 

CAUTION 

The specifications contained in this document must be applied in order to comply with the essential 

The drive must be installed and set up in accordance with both international and national standards. 

Bringing the device into conformity is the responsibility of the systems integrator who must observe the 

EMC directive among others within the European Union. 

requirements of the EMC directive.

(4) Current values given with an additional line choke. 

(5) These power levels are for a maximum switching frequency of 2 or 4 kHz, depending on the rating, and 

continuous operation. Switching frequencies are detailed in the section on "Technical Specifications". 

Using the ATV38 with a higher switching frequency: 

• For continuous operation derate by one power rating, for example: 

ATV38HU18N4 for 0.37 kW – ATV38HD12N4 for 5.5 kW. 

• If no power derating is applied, do not exceed the following operating conditions: 

Cumulative running time 36 s maximum per 60 s cycle (load factor 60%). 

(6) For 60 seconds. 

(7) These power levels are given for the maximum permissible switching frequency in continuous operation (2 

or 4 kHz, depending on the rating). 

(8) For ATV38HU18N4 to D79N4: the Altivar 38 is fitted with an integral EMC filter. 

For ATV38HD25N4(X) to D79N4(X): add X to the reference to receive an Altivar 38 without integral EMC 

filter. 

For ATV38HC10N4X to C33N4X: the Altivar 38 is not fitted with an integral EMC filter. Optional external 

filters are available.

4 Torque at overspeed with constant power 

Available overtorque: 

Variable torque applications: 

• 110% of the nominal motor torque for 60 seconds. 

Continuous operation 

For self-cooled motors, cooling is linked to the motor speed. Derating therefore occurs at speeds of less than 

half the nominal speed. 

Overspeed operation 

As the voltage can no longer change with the frequency, induction in the motor is reduced which results in a 

reduction in torque. Check with the manufacturer that the motor can operate at overspeed. 

Note: With a special motor, the nominal and maximum frequencies can be adjusted between 10 and 500 Hz 

using the operator terminal or PowerSuite tools.

Mounting in a Wall-fixing or Floor-standing 

Enclosure 

Observe the mounting recommendations on the previous page. 

To ensure proper air circulation in the drive: 

- Fit ventilation grilles 

- Ensure that ventilation is adequate: if not, install 

forced ventilation with a filter 

- Use special IP 54 filters 

Dust and damp proof metal wall-fixing or floor-standing 

enclosure (IP 54 degree of protection) 

The drive must be mounted in a dust and damp proof casing in certain environmental conditions: dust, 

corrosive gases, high humidity with risk of condensation and dripping water, splashing liquid, etc. 

ENGLISH 

To avoid hot spots in the drive, add a fan to circulate the air inside the enclosure, reference VW3A5882• (see 

ATV38 catalogue). 

This enables the drive to be used in an enclosure where the maximum internal temperature can reach 60 °C. 

Calculating the size of the enclosure 

Maximum thermal resistance Rth (°C/W) : 

Rth = 

θ° - θ°e 

P 

θ° = maximum temperature inside enclosure in °C 

θ°e = maximum external temperature in °C 

P = total power dissipated in the enclosure in W 

Power dissipated by the drive: see section Selecting a drive. 

Add the power dissipated by the other equipment components. 

Useful heat dissipation surface of enclosure S (m 2 ): 

(sides + top + front panel if wall-mounted) 

S = 

K 

Rth 

K = enclosure thermal resistance per m 2 

For metal enclosure: 

K = 0.12 with internal fan 

K = 0.15 without fan 

Caution: Do not use insulated enclosures, as they have a poor level of conductivity.

Electromagnetic Compatibility - Wiring 

Altivar 38 with integral EMC filter ATV38HU18N4 to HD79N4 

Principle 

• Grounds between drive, motor and cable shielding must have "high frequency" equipotentiality. 

• Use shielded cables with shielding connected to the ground at both ends of the motor cable, braking resistor 

(if fitted) and control-signalling cables. Conduit or metal ducting can be used for part of the shielding length 

provided that there is no break in continuity. 

• Ensure maximum separation between the power supply cable (line supply) and the motor cable.

3 Non-shielded power supply wires or cable. 

4 Non-shielded wires for the output of the safety relay contacts. 

5 Fix and ground the shielding of cables 6, 7 and 8 as close as possible to the drive: 

- strip the cable to expose the shielding 

- use the clamps supplied to fix the stripped part of the shielding to the metal plate 1 

The shielding must be clamped tightly enough to the metal plate to ensure good contact. 

6 Shielded cable for motor connection with shielding connected to ground at both ends. 

The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes. 

7 Shielded cable for connecting the control/signalling wiring. 

For applications requiring several conductors, use small cross-sections (0.5 mm 2 ). 

The shielding must be connected to ground at both ends. The shielding must be continuous and 

intermediate terminals must be in EMC shielded metal boxes. 

8 Shielded cable for connecting braking resistor (if fitted). The shielding must be connected to ground at both 

ends. The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes. 

Note: 

• If using an additional input filter, it should be mounted behind the drive and connected directly to the line 

supply via an unshielded cable. Link 3 to the drive is then via the filter output cable. 

• The HF equipotential ground connection between the drive, motor and cable shielding does not remove the 

need to connect the PE protective conductors (green-yellow) to the appropriate terminals on each unit.

Line chokes are compulsory if the line supply prospective short-circuit current is less than 22 kA. These chokes 

can be used to provide improved protection against overvoltages on the line supply and to reduce harmonic 

distortion of the current produced by the drive. The chokes are used to limit the line current. 

ENGLISH 

Principle 

• Grounds between drive, motor and cable shielding must have "high frequency" equipotentiality. 

• Use shielded cables with shielding connected to the ground at both ends of the motor cable, and controlsignalling 

cables. Conduit or metal ducting can be used for part of the shielding length provided that there 

is no break in continuity. 

• Ensure maximum separation between the power supply cable (line supply) and the motor cable. 

Power wiring 

The power wiring should consist of cables with 4 conductors or individual cables maintained as close as 

possible to the PE cable. Take care to route the motor cables well away from the power supply cables. 

The power supply cables are not shielded. If a radio interference filter is used, the grounds for the filter and the 

drive should be at the same potential with low-impedance links at high frequency (fixed to unpainted metal 

plate with anti-corrosion treatment/machine ground wiring). The filter should be fitted as close as possible to 

the drive. 

If the environment is sensitive to radiated radio interference, the motor cables should be shielded. On the drive 

side, fix and connect the shielding to the machine ground with rustproof clamps. The main function of the motor 

cable shielding is to limit their radio frequency radiation. Therefore, use 4-pole cables for the motor, connecting 

each end of the shielding in accordance with established practice for High Frequency wiring. The type of 

protective material (copper or steel) is less important than the quality of the connection at both ends. An 

alternative is to use a metal cable duct with good conductivity and no break in continuity. 

Note: when using a cable with a protective sleeve (NYCY type) which fulfils the dual function of PE + screen, 

it must be connected correctly to both the drive and the motor (its radiation efficiency is reduced). 

Control wiring 

Shielding clamp 

Cable grip. Check that the cable follows the path indicated 

by the clips

Wiring Recommendations, Use 

Wiring recommendations 

Power 

Observe the cable cross-sectional areas recommended in the standards. 

The drive must be earthed to conform with the regulations concerning high leakage currents (over 3.5 mA). Do 

not use a residual current device for upstream protection on account of the DC elements which may be 

generated by leakage currents. If the installation involves several drives on the same line, each drive must be 

earthed separately. If necessary, fit a line choke (consult the catalogue). 

Keep the power cables separate from circuits in the installation with low-level signals (detectors, PLCs, 

measuring apparatus, video, telephone). 

Control 

Keep the control circuits away from the power cables. For control and speed reference circuits, we recommend 

using shielded twisted cables with a pitch of between 25 and 50 mm connecting the shielding to each end. 

Recommendations for use 

With power switching via line contactor: 

ENGLISH 

- Avoid operating contactor KM1 frequently (premature ageing of the filter capacitors). Use 

inputs LI1 to LI4 to control the drive 

- these steps are essential in the event of cycles: 

of less than 60 seconds for ATV38HU18N4 to HD79N4(X) 

of less than 180 seconds for ATV38HC10N4X to ATV38HC33N4X 

If safety standards necessitate isolation of the motor, fit a contactor on the drive output and use the 

"downstream contactor control" function (consult the programming manual). 

Fault relay, unlocking 

The fault relay is energized when the drive is powered up and is not faulty. It has one C/O contact at the 

common point. 

The drive is unlocked after a fault by: 

• powering down the drive until both the display and indicator lamps go out, then powering up again 

• automatically or remotely via logic input: consult the programming manual

Drive Menu 


SFt Sw Freq.Type LF-HF1-HF2 LF 

Used to select a low switching frequency (LF) or a high switching frequency (HF1 or HF2). HF1 

switching is designed for applications with a low load factor without derating the drive. If the thermal 

state of the drive exceeds 95%, the frequency automatically changes to 2 or 4 kHz depending on 

the drive rating. When the thermal state of the drive drops back to 70%, the selected switching 

frequency is re-established. HF2 switching is designed for applications with a high load factor with 

derating of the drive by one rating: the drive parameters are scaled automatically (torque limit, 

thermal current, etc). 

Modifying this parameter results in the following parameters returning to factory 

settings : 

• nCr, CLI, Sfr, nrd (Drive menu) 

• ItH, IdC,Ctd (Adjust menu) 

SFr Sw Freq - kHz 0.5-1-2-4 -8-12-16 kHz According to drive rating 

Used to select the switching frequency. The adjustment range depends on the SFt parameter. 

If SFt = LF: 0.5 to 2 or 4 kHz according to the drive rating 

If SFt = HF1 or HF2: 2 or 4 to 16 kHz according to the drive rating 

The maximum operating frequency (tFr) is limited according to the switching frequency:

Logic input application functions 

Operating direction: forward/reverse 

Reverse operation can be disabled for applications requiring only a single direction of motor rotation. 

2-wire control 

Run (forward or reverse) and stop are controlled by the same logic input, for which state 1 (run) or 0 (stop), or 

a change in state is taken into account (see the 2-wire control menu). 

3-wire control 

Run (forward or reverse) and stop are controlled by 2 different logic inputs. 

LI1 is always assigned to the stop function. A stop is obtained on opening (state 0). 

The pulse on the run input is stored until the stop input opens. 

ENGLISH 

During power-up or a manual or automatic fault reset, the motor can only be supplied with power after prior 

resetting of the “forward”, “reverse”, and “injection stop” commands. 

Ramp switching : 1 st ramp: ACC, dEC; 2 nd ramp: AC2, dE2 

Two types of activation are possible: 

- activation of a logic input LIx 

- detection of an adjustable frequency threshold 

If a logic input is assigned to the function, ramp switching can only be performed by this input. 

Step by step operation (JOG): Low speed operation pulse 

If the JOG contact is closed and then the operating direction contact is actuated, the ramp is 0.1 s irrespective 

of the ACC, dEC, AC2, dE2 settings. If the direction contact is closed and the JOG contact is then actuated, 

the configured ramps are used. 

Parameters which can be accessed in the adjust menu: 

- JOG speed 

- anti-repeat delay (minimum time between 2 “JOG” commands) 

107


+/- speed: Two types of operation are available. 

1 Use of single action buttons: two logic inputs are required in addition to the operating direction(s). 

The input assigned to the “+ speed” command increases the speed, the input assigned to the “- speed” 

command decreases the speed. 

This function accesses the STr save reference parameter in the Control menu. 

2 Use of double action buttons: only one logic input assigned to + speed is required. 

+ speed/- speed with double action buttons: 

Description: 1 button pressed twice for each direction of rotation. 

Each action closes a volt-free contact.

In both cases, the maximum speed is given by the references applied to the analog inputs. For 

example, connect AI1 to the +10V. 

108

To configure the AI1/AI2 reference switching: 

- Verify that the LI is not configured to "RFC:Auto/Manu" (if so, configure the LI to "NO:Not assigned"). 

- Configure a LI to "RFC:Auto/Manu". The second reference is then AI2. 

To configure the AI1/AI3 reference switching: 

- Verify that the LI is not configured to "RFC:Auto/Manu" (if so, configure the LI to "NO:Not assigned"). 

- Configure AI3 to "FR2:Speed Ref2". 

- Configure a LI to "RFC:Auto/Manu". The second reference is then AI3.

Causes the motor to stop using the resistive torque only. The motor power supply is cut. 

A freewheel stop is obtained when the logic input opens (state 0). 

DC injection stop 

An injection stop is obtained when the logic input closes (state 1). 

Fast stop 

Braked stop with the deceleration ramp time reduced by a reduction factor dCF which appears in the drive 

menu. 

A fast stop is obtained when the logic input opens (state 0). 

109


Motor switching 

This function enables two motors with different ratings to be powered by the same drive in succession, with 

switching performed by an appropriate sequence at the drive output. Switching must take place with the motor 

stopped, and the drive locked. The following internal parameters are switched automatically by the logic 

command: 

- nominal motor current 

- injection current 

This function automatically disables thermal protection on the second motor. 

Accessible parameter: Ratio of PCC motor ratings in the drive menu. 

Fault reset 

Two types of reset are available: partial or general (rSt parameter in the "fault" menu). 

Partial reset (rSt = RSP): 

Used to clear the stored fault and reset the drive if the cause of the fault has disappeared. 

Faults affected by partial clearing: 

- line overvoltage - communication fault - motor overheating 

- DC bus overvoltage - motor overload - serial link fault 

- motor phase loss - loss of 4-20 mA - drive overheating 

- overhauling - external fault - overspeed 

ENGLISH 

General reset (rSt = RSG): 

This inhibits all faults (forced operation) except SCF (motor short circuit) while the assigned logic input 

is closed. 

Forced local mode 

Used to switch between line control mode (serial link) and local mode (controlled via the terminal strip or via 

the terminal). 

Auto-tuning 

When the assigned logic input changes to 1 an auto-tuning operation is triggered, in the same way as 

parameter tUn in the “drive” menu. 

Caution: Auto-tuning will only be performed if no command has been activated. If a "freewheel stop" 

or "fast stop" function has been assigned to a logic input, this input must be set to 1 (active at 0). 

Application: Motor switching for example. 

Preset PI auto-man, PI reference: See PI function (page 111) 

External fault 

When the assigned logic input changes to 1, the motor stops (according to the configuration of the LSF 

Stop+flt parameter in the Drive menu), and the drive locks in EPF external fault fault mode. 

Force to keypad 

Enables a LI to be used to select for local control: 

If LIX=FTK and FTK=0: operation by the control terminals 

If LIX=FTK and FTK=1: control by the keypad 

- If LIX=FTK, the LCC function in the control menu is no longer accessible by the keypad. In 

consequence it is impossible to control the drive by the keypad. 

- When FTK has been disactivated it is neccesary to revalidate the function LCC again in the 

control menu. 

110


Analog input application functions 

Input AI1 is always the speed reference. 

Assignment of AI2 and AI3 

Summed speed reference: The frequency references provided by AI2 and AI3 can be summed with AI1. 

Speed regulation with tachogenerator: (Assignment to AI3 only with an I/O extension card with analog 

input): used for speed correction via tachogenerator feedback. 

An external divider bridge is required to adapt the voltage of the tachogenerator. The maximum voltage must 

be between 5 and 9 V. A precise setting is then obtained by setting parameter dtS available in the adjust menu. 

ENGLISH 

PTC probe protection: (only with an I/O extension card with analog input). Used for the direct thermal 

protection of the motor by connecting the PTC probes in the motor windings to analog input AI3. 

PTC probe characteristics: 

Total resistance of the probe circuit at 20 °C = 750 Ohms. 

PI regulator: Used to regulate a process with a reference and a feedback given by a sensor. In PI mode the 

ramps are all linear, even if they are configured differently. 

With the PI regulator, it is possible to: 

- Adapt the feedback via FbS. 

- Correct PI inversion. 

- Adjust the proportional and integral gain (RPG and RIG). 

- Assign an analog output for the PI reference, PI feedback and PI error. 

- Apply a ramp to establish the action of the PI (AC2) on start-up if PSP > 0. 

If PSP = 0 the active ramps are ACC/dEC. The dEC ramp is always used when stopping. 

The motor speed is limited to between LSP and HSP. 

Note: PI regulator mode is active if an AI input is assigned to PI feedback. This AI assignment can only be 

made after disabling any functions incompatible with PI (see page 106).

Encoder input application functions 

(only with an I/O extension card with encoder input) 

Speed regulation: Used to correct the speed via an incremental encoder or detector. (See documentation 

supplied with the card). 

ENGLISH 

Summed speed reference: The reference provided by the encoder input is summed with AI1. (see 

documentation supplied with the card) 

Applications: 

- Synchronization of the speed of a number of drives. Parameter PLS on the "drive" menu is used to adjust 

the speed ratio of one motor in relation to that of another. 

- Reference via encoder. 

Logic output application functions 

Relay R2, LO solid state output (with I/O extension card) 

Downstream contactor control (OCC): can be assigned to R2 or LO 

Enables the drive to control an output contactor (located between the drive and the motor). The request to close 

the contactor is made when a run command appears. The request to open the contactor is made when there 

is no current to the motor. 

If a DC injection braking function has been configured, it should not be left operating too long in stop 

mode, as the contactor only opens at the end of braking. 

Drive running (RUN): can be assigned to R2 or LO 

The logic output is at state 1 if the motor power supply is provided by the drive (current present) or if a run

Fault Menu 


Modifications can only be made in stop mode with the drive locked. 

Code Description Factory 

setting 

Atr Auto Restart No 

ENGLISH 

This function is used to restart the drive automatically if the fault has disappeared (Yes/No option). 

Automatic restarting is possible after the following faults: 

- line overvoltage 

- DC bus overvoltage 

- external fault 

- motor phase loss 

- serial link fault 

- communication fault 

- loss of 4-20 mA signal 

- motor overload (condition: motor thermal state less than 100%) 

- drive overheating (condition: drive thermal state less than 70%) 

- motor overheating (condition: resistance of probes less than 1,500 Ohms) 

When the function is activated, following appearance of one or more of these faults, the R1 relay 

stays closed: the drive attempts to start every 30 s. A maximum of 6 attempts are made with the 

drive unable to start (fault present). If all 6 fail, the drive remains locked definitively with the fault 

relay open, until it is reset by being switched off. 

This function requires the associated sequence to be maintained. Ensure that accidental 

restarting will not pose any danger to either equipment or personnel. 

rSt Reset Type RSP 

This function can be accessed if fault reset is assigned to a logic input. 2 possible options: partial 

reset (RSP), general reset (RSG) 

Faults affected by a partial reset (rSt = RSP) 

- line overvoltage 

- motor overload 

- motor overheating 

- motor phase loss 

- serial link fault 

- communication fault 

- DC bus overvoltage 

- loss of 4-20 mA 

- overhauling 

- drive overheating 

- external fault 

- overspeed 

Faults affected by a general reset (rSt = RSG): all faults. The general reset actually inhibits all faults 

(forced operation). 

To configure rSt = RSG: 

1 Display RSG 

2 Press the "ENT" key 

3 The drive displays "See manual" 

4 Press ▲ then ▼ then "ENT" 

OPL OutPhaseLoss Yes

frequency. Force-cooled motor (FCL): the drive does not take account of any derating depending on 

the rotation frequency. 

LFL LossFollower No 

Used to enable the loss of 4-20 mA reference fault. 

This fault can only be configured if the AI2 min/max reference parameters (CrL and CrH) are greater 

than 3 mA or if CrL>CrH. 

- No: no fault 

- Yes: immediate fault 

- Stt: stop according to the Stt parameter, without a fault, restart when the signal returns 

- LSF: stop according to the Stt parameter, then fault at the end of stopping 

- LFF: force to the fallback speed set by the LFF parameter 

- RLS: maintaining the speed reached on appearance of the loss of 4-20 mA signal, without a 

fault, restarting when the signal returns. 

LFF 4-20 Flt Spd 0 

Fallback speed in the event of loss of 4-20 mA signal. 

Adjustment from 0 to HSP. 

FLr Catch On Fly Yes 

Used to enable a smooth restart after one of the following events: 

- loss of line supply or simple power off 

- fault reset or automatic restart 

- freewheel stop or injection stop with logic input 

- uncontrolled loss downstream of the drive 

Choice Yes/No 

StP Cont. Stop No 

Controlled stop on a line phase loss. This function is only operational if parameter IPL is set to No. 

If IPL is set to Yes, leave StP in position No. Possible options: 

No: locking on loss of line supply 

MMS: Maintain Bus: the drive control unit continues to be powered by the kinetic energy generated 

by the inertia forces, until the USF fault (undervoltage) occurs 

FRP: Follow Ramp: deceleration following the programmed dEC or dE2 ramp until a stop or until the 

USF fault (undervoltage) occurs 

Sdd RampNotFoll Yes 

This function can be accessed if a tachogenerator or pulse generator feedback has been 

programmed. When enabled, it is used to lock the drive if a speed error is detected (difference 

between the stator frequency and the measured speed).

FAULT 

green POWER LED on: Altivar powered up 

red FAULT LED • on: Altivar faulty 

• flashing: Altivar locked once the “STOP” key has 

been pressed on the terminal or after a change to 

the configuration. The motor can then only be 

supplied with power after first resetting the 

“forward”, “reverse”, and “injection stop” commands. 

Display mode on terminal screen 

Displays preset frequency reference, or fault. 

The display mode can be modified via the terminal: consult the programming manual. 

Maintenance 

ENGLISH 

Before performing any work on the drive, switch off the power supply, check that the green LED has gone 

off, and wait for the capacitors to discharge (3 to 10 minutes depending on the drive power rating). 

The DC voltage at the + and - terminals or PA and PB terminals may reach 850 V depending 

on the line supply voltage. 

If a problem arises during setup or operation, ensure that the recommendations relating to the environment, 

mounting and connections have been observed. 

Servicing 

The Altivar 38 does not require preventative maintenance. We nevertheless advise you regularly to: 

• Check the condition and tightness of connections 

• Ensure that the temperature around the unit remains at an acceptable level and that ventilation is effective 

(average service life of fans: 3 to 5 years depending on operating conditions) 

• Remove any dust from the drive 

Assistance with maintenance 

The first fault detected is stored and displayed on the terminal display: the drive locks, the red LED (FAULT) 

illuminates, and fault relay R1 trips. 

Clearing the fault 

• Cut the power supply to the drive in the event of a non-resettable fault. 

• Locate the cause of the fault in order to eliminate it. 

• Reconnect the power supply: this clears the fault if it has disappeared. 

• In some cases there may be an automatic restart once the fault has disappeared if this function has been 

programmed. 

Spares and repairs 

For spare parts and repairs to Altivar 38 drives, consult Schneider group product support.
