Trip
HF28 Power stage thermistor 2 fault, or internal fan fault (size 3)
228 Hardware fault - return drive to supplier
HF29 Control board thermistor fault
229 Hardware fault - return drive to supplier
HF30 DCCT wire break trip from power module
230 Hardware fault - return drive to supplier
HF31 Internal capacitor bank fan failure (size 4 and larger) or a module has not powered up in a multi-module parallel drive
Check the AC or DC power supply to all modules in a multi-module parallel drive
231
If the AC or DC power supply is present, or if this is a single drive, then there is a hardware fault - return drive to the supplier
HF32 Power stage - Identification and trip information serial code error
232 Hardware fault - return drive to the supplier
It.AC
Output current overload timed out (I
Ensure the load is not jammed / sticking
Check the load on the motor has not changed
If seen during an autotune in servo mode, ensure that the motor rated current Pr 0.46 (Pr 5.07) or Pr 21.07 is ≤Heavy Duty current
rating of the drive
20
Tune the rated speed parameter (closed loop vector only)
Check feedback device signal for noise
Check the feedback device mechanical coupling
Ensure that the motor rated current is not set to zero
It.br
Braking resistor overload timed out (I
Ensure the values entered in Pr 10.30 and Pr 10.31 are correct
Increase the power rating of the braking resistor and change Pr 10.30 and Pr 10.31
19
If an external thermal protection device is being used and the braking resistor software overload is not required, set Pr 10.30 or
Pr 10.31 to 0 to disable the trip
