Fault tracing

Motor overtem-
perature

Motor is overloaded.

Decrease motor load.
If no motor overload exists, check
the temperature model parame-
ters.

Motor Under-
load

Motor is under loaded

Check load.

Power overload Supervision for drive power

Drive power is to high: decrease
load.

Watchdog

Error in the microprocessor monitor-
ing
Malfunction
Component fault

Reset the fault and restart.
If the fault occurs again, please
contact your closest Vacon repre-
sentative.

Back EMF

Protection of unit when starting with
rotating motor

Reset the fault and restart.
Should the fault re-occur, contact
the distributor near to you.

STO fault

Safe torque off signal does not allow
drive to be set as ready

Reset the fault and restart.
Should the fault re-occur, contact
the distributor near to you.

Application
error

The application is not working

Please contact your closest Vacon
representative.

IGBT temp

IGBT temperature (UnitTempe
I2T) too high

Check loading.
Check motor size.
Make identification run.

4 mA fault
(Analog input)

Selected signal range: 4...20 mA (see
Application Manual)
Current less than 4 mA
Signal line broken detached
The signal source is faulty

Check the analog input’s current
source and circuit.

External fault

Error message on digital input. The
digital input was programmed as an
input for external error messages. The
input is active.

Check the programming and
check the device indicated by the
error message.
Check the cabling for the respec-
tive device as well.

Keypad
communication
fault

The connection between the control
keypad and the frequency converter is
broken.

Check keypad connection and key-
pad cable.

Fieldbus
communication
fault

The data connection between the field-
bus master and fieldbus board is bro-
ken

Check installation and fieldbus
master.

Fieldbus
Interface error

Defective option board or slot

Check board and slot.

Wrong run
command

Wrong run alarm and stop command

Run forward and backward are
activated at the same time

Brake time out

Threshold for brake open are not
reached

Check the settings of the mechan-
ical brake and of the motor.

Identification

Identification alarm

Motor identification has not been
successfully completed
