3291 BU DC link difference Difference in DC voltages between
parallel-connected inverter modules. Check the auxiliary code (format
XXXY YYZZ). “XXX” specifies the
source of the first error (see “YYY”).
“YYY” specifies the module through
which BCU control unit channel the
fault was received (
1 : Channel 1, 2 :
Channel 2, 4 : Channel 3, 8 : Channel
4, …, 800: Channel 12).
3381 Output 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 [0].
3381 Output phase loss Motor circuit fault due to missing
motor connection. Connect motor cable.
4110 Control board
temperature Control board temperature is too
high. Check proper cooling of the drive and
auxiliary cooling fan.
4210 IGBT overtemperature Estimated drive IGBT temperature is
excessive.
Check ambient conditions, air flow
and fan, dust pick-up in heatsink fins
and motor power.
4290 Cooling Drive module temperature is
excessive. Check ambient temperature, air flow
and fan operation, dust pick-up in
heatsink. Clean whenever necessary.
42F1 IGBT temperature Drive IGBT temperature is
excessive. Check ambient conditions, air flow
and fan, dust pick-up in heatsink fins
and motor power.
4310 Excess temperature Power unit module temperature is
excessive. Check ambient conditions, air flow
and fan, dust pick-up in heatsink fins
and motor power.
4380 Excess temperature
difference High temperature difference between
the IGBTs of different phases. Check motor cabling and drive
module(s) cooling.
4981 External temperature 1 Measured temperature 1 has
exceeded fault limit.
Check parameter 35.02 Measured
temperature 1 , motor cooling and fault
limit for measured temperature 1.
4982 External temperature 2 Measured temperature 2 has
exceeded fault limit.
Check parameter 35.03 Measured
temperature 2 , motor cooling and fault
limit for measured temperature 1.
4991 Safe motor
temperature The CPTC-02 module indicates
overtemperature:
• motor temperature is too high, or
• the thermistor is in short circuit. Check the cooling of the motor.
Check the motor load and drive
ratings. Check the wiring of the
temperature sensor. Repair wiring if
faulty.
Measure the resistance of the sensor.
Replace the sensor if faulty.
5080 Fan Cooling fan is stuck or disconnected. Check fan operation and connection.
Replace fan if faulty.
5081 Auxiliary fan broken An auxiliary cooling fan is stuck or
disconnected.
1 – Auxiliary fan 1 broken
2 – Auxiliary fan 2 broken Check auxiliary fan(s) and
connection(s). Replace fan if faulty.
5091 Safe torque off Safe torque off function is active. Check safety circuit connections
