Cause
Drive module temperature is excessive.
Drive IGBT temperature is excessive.
Power unit module temperature is
excessive.
High temperature difference between
the IGBTs of different phases.
Measured temperature 1 has exceeded
fault limit.
Measured temperature 2 has exceeded
fault limit.
An auxiliary cooling fan (connected to
the fan connectors on the control unit) is
stuck or disconnected.
STO hardware diagnostics has detected
hardware failure.
Safe torque off function is active, ie.
safety circuit signal(s) connected to
connector STO is broken during start or
run.
Power unit memory has cleared.
The hardware of the drive does not
match the information stored in the
memory. This may occur eg. after a
firmware update.
Problem with internal temperature
measurement of the drive.
Cooling fan stuck or disconnected.
Communication errors detected
between the drive control unit and the
power unit.
Connection between the drive control
unit and the power unit is lost.
What to do
Check ambient temperature. If it
exceeds 40 °C/104 °F (frames R5...R9)
or if it exceeds 50 °C /122 °F (frames
R0...R9), ensure that load current does
not exceed derated load capacity of
drive. See chapter Technical data,
section Derating in the Hardware
manual of the drive.
Check drive module cooling air flow and
fan operation.
Check inside of cabinet and heatsink of
drive module for dust pick-up. Clean
whenever necessary.
Check ambient conditions. Check air
flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check ambient conditions. Check air
flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check the motor cabling.
Check cooling of drive module(s).
Check the value of parameter 35.02
Measured temperature 1.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter 35.03
Measured temperature 2.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check auxiliary fan(s) and
connection(s). Replace fan if faulty.
Make sure the front cover of the drive
module is in place and tightened.
Reboot the control unit (using
parameter
96.08 Control board boot) or by cycling
power.
Contact your local ABB representative
for hardware replacement.
Check safety circuit connections. For
more information, see chapter The Safe
torque off function in the Hardware
manual of the drive and description of
parameter 31.22 STO indication run/
stop (page 183).
Check the value of parameter 95.04
Control board supply.
Contact your local ABB representative.
Cycle the power to the drive. You may
have to be repeat this.
Contact your local ABB representative.
Check fan operation and connection.
Replace fan if faulty.
Check the connection between the drive
control unit and the power unit.
Check the value of parameter 95.04
Control board supply.
Check the connection between the
control unit and the power unit.
