A4A1 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.
A4A9 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.

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.
A4B1 Excess
temperature
difference
High temperature
difference between the
IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive
module(s).
A4F6 IGBT temperature 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.
