Output phase loss
Programmable fault:
31.19
Motor phase loss
Motor circuit fault due to
missing motor connection (any
of the three phases not
connected).
In scalar control mode, the
drive detects fault only when
the output frequency is above
10% of the motor nominal
frequency.
Connect motor cable.
If the drive is in scalar mode and nominal
current of the motor is less than 1/6 of the
nominal output current of the drive, set

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
50 °C /122 °F, 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.
42F1
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.
4310
Excess temperature
Power unit module
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.
4380
Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
