Cause What to do
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Contact an ABB service
representative for control board
replacement.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
Check ambient temperature. If it
exceeds 40 °C/104 °F (IP21 frames
R4 R9) or if it exceeds 50 °C /122 °F
...
(IP21 frames R1
load current does not exceed derated
load capacity of drive. For all P55
frames, check the derating
temperatures. 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 the motor cabling.
Check cooling of drive module(s).
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
Check the auxiliary code to identify
the fan. Code 0 denotes main fan 1.
Other codes (format XYZ): "X"
specifies state code (1: ID run, 2:
normal). "Y" = 0, "Z" specifies the
index of the fan (1: Main fan 1, 2:
Main fan 2, 3: Main fan 3).
Check fan operation and connection.
Replace fan if faulty.
