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.
Cooling fan stuck or
disconnected.
An auxiliary cooling fan is
stuck or disconnected.
Safe torque off hardware
failure.
Safe torque off function is
active, i.e. safety circuit
31.22
signal(s) connected to
connector XSTO 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 unit. This
may occur eg. after a firmware
update or memory unit
replacement.

What to do
Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity of
drive. See appropriate Hardware Manual.
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
Measured temperature 1.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter
Temperature 1 fault limit.
Check the value of parameter
Measured temperature 2.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter
Temperature 2 fault limit.
Check fan operation and connection.
Replace fan if faulty.
Check auxiliary fan(s) and connection(s).
Replace fan if faulty.
Contact your local ABB representative.
Check safe torque off circuit connections.
