590 Fault tracing
4000
Motor cable overload
Calculated motor cable
temperature has exceeded
warning limit.
Check the settings of parameters 35.61
and 35.62.
Check the dimensioning of the motor
cable in regard to required load.
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 °C (104 °F), ensure that load current
does not exceed derated load capacity of
drive. See appropriate Hardware manual.
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.
See A4B0 Excess temperature (page
571).
4380 Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
See A4B1 Excess temperature
difference (page 572).
4381 PCB space cooling Temperature difference
between ambient and drive
module PCB space is
excessive.
See A4B2 PCB space cooling (page
572).
4981 External temperature
1
(Editable message text)
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).
Check the value of parameter 35.12
Temperature 1 fault limit.
4982 External temperature
2
(Editable message text)
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).
Check the value of parameter 35.22
Temperature 2 fault limit.
4990 FPTC not found A thermistor protection module
has been activated by
parameter 35.30 but cannot be
detected.
Power down the control unit and make
sure that the module is properly inserted
in the correct slot.
The last digit of the auxiliary code
identifies the slot.
