HF19 Temperature feedback multiplexing failure, or thermistor is open or short circuit
219 Hardware fault - return drive to supplier
HF20 Power stage recognition: serial code error
220 Hardware fault - return drive to supplier
HF21 Power stage recognition: unrecognised frame size
221 Hardware fault - return drive to supplier
HF22 Power stage recognition: multi module frame size mismatch
222 Hardware fault - return drive to supplier
HF23 Power stage recognition: multi module voltage rating mismatch
223 Hardware fault - return drive to supplier
HF24 Power stage recognition: unrecognised drive size
224 Hardware fault - return drive to supplier
HF25 Current feedback offset error
225 Hardware fault - return drive to supplier
Soft start relay failed to close, soft start monitor failed or braking IGBT short circuit at

226 Hardware fault - return drive to supplier
HF27 Power stage thermistor 1 fault
227 Hardware fault - return drive to supplier
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
Internal capacitor bank fan failure (size 4 and larger) or a module has not powered up in a
HF31
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 then it 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
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
L.SYnC Drive failed to synchronise to the supply voltage in Regen mode
39 Refer to the Diagnostics chapter in the Unidrive SP Regen Installation Guide.
O.CtL Drive control board over temperature
Check cubicle / drive fans are still functioning correctly
Check cubicle ventilation paths
23 Check cubicle door filters
Check ambient temperature
Reduce drive switching frequency
