PSU
Internal power supply fault
5
The
PSU
trip indicates that one or more internal power supply rails are outside limits or overloaded.
* For a parallel power-module system the rectifier number will be zero as it is not possible to determine which rectifier has
detected the fault.
Recommended actions:
•
Remove any option modules and perform a reset
•
Remove encoder connection and perform a reset
•
Hardware fault within the drive – return the drive to the supplier
PSU 24V
24V internal power supply overload
9
The total user load of the drive and option modules has exceeded the internal 24 V power supply limit. The user load
consists of the drive digital outputs and main encoder supply.
Recommended actions:
•
Reduce the load and reset
•
Provide an external 24 V power supply on control terminal 2
•
Remove all option modules

Resistance
Measured resistance has exceeded the parameter range
33
This trip indicates that either the value being used for motor stator resistance is too high or that an attempt to do a test
involving measuring motor stator resistance has failed. The maximum for the stator resistance parameters is generally
higher than the maximum value that can be used in the control algorithms. If the value exceeds (V
FS
/ v2) /
Full Scale
Current Kc
(11.061), where V
FS
is the full scale DC bus voltage then this trip is initiated. If the value is the result of a
measurement made by the drive then sub-trip 1 is applied, or if it is because the parameter has been changed by the user
then sub-trip 3 is applied. During the stator resistance section of auto-tuning an additional test is performed to measured
the drive inverter characteristics to provide the compensation necessary for dead-times. If the inverter characteristic
measurement fails then sub-trip 2 is applied.
Recommended actions:
•
Check that the value that has been entered in the stator resistance does not exceed the allowed range (for the
presently selected motor map)
•
Check the motor cable / connections
•
Check the integrity of the motor stator winding using a insulation tester
•
Check the motor phase to phase resistance at the drive terminals
•
Check the motor phase to phase resistance at the motor terminals
•
Ensure the stator resistance of the motor falls within the range of the drive model
•
Select fixed boost mode (Pr
05.014
= Fixed) and verify the output current waveforms with an oscilloscope
•
Replace the motor
