Control board
temperature
Control board
temperature is too high.
Check proper cooling of the drive.
Check the auxiliary cooling fan.
4210
IGBT
overtemperature
Estimated drive IGBT
temperature is excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-
up.
Check motor power against drive
power.
4290 Cooling
Drive module
temperature is excessive.
Check ambient temperature. If it
exceeds 40%/104 °F (frames
R4…R8) or if it exceeds 50% /122
°F (frames R0…R8), 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.
4380 Excess
temperature
difference
High temperature
difference between the
IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
