426 Fault tracing
3381 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
parameter
31.19
Motor phase loss to No
action .
4110 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.
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).
4981 External temperature
1 Measured temperature 1 has
exceeded fault limit. Check the value of parameter 35.02
Measured temperature 1 .
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
4982 External temperature
2 Measured temperature 2 has
exceeded fault limit. Check the value of parameter 35.03
Measured temperature 2 .
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
