Cause
Drive IGBT temperature is
excessive.
Communication errors
detected between the drive
control unit and the power unit.
Safe torque off function is
active, i.e. safety circuit
signal(s) connected to
connector XSTO is lost.
Problem with internal
temperature measurement of
the drive.
Power unit power supply
failure.
Communication errors
detected between the drive
control unit and the power unit.
Measurement circuit fault.
Measurement circuit fault.
State feedback from output
phases does not match control
signals.
Charging feedback signal
missing.
The motor parameters are set
incorrectly.
The drive is not dimensioned
correctly.
Parameters in group 99 have
not been set.
The supply voltage has not
been defined.
The drive does not have a
functionality requested by a
PLC, or requested functionality
has not been activated.
The drive does not have a
functionality requested by a
PLC, or requested functionality
has not been activated.

What to do
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check the connections between the drive
control unit and the power unit.
Check safety circuit connections. For
more information, see appropriate drive
hardware manual and description of
parameter 31.22 STO indication run/stop
(page 198).

Check the feedback signal coming from
the charging system.
Check the settings of the motor
configuration parameters in group 99.
Check that the drive is sized correctly for
the motor.
Check that all the required parameters in
group 99 have been set.
Note: It is normal for this warning to
appear during the start-up and continue
until the motor data is entered.
