Trip
Power Comms Communication has been lost / errors detected between power, control and rectifier modules
A Power Comms trip indicates a communications problem within the power system of the drive. The reason for the trip can
be identified by the sub-trip number.
Type of drive
Single power
90
module system
Recommended actions:
• Hardware fault - contact the supplier of the drive.
Power Down Save Power down save error
The Power Down Save trip indicates that an error has been detected in the power down save parameters saved in non-
volatile memory.
37
Recommended actions:
• Perform a 1001 save in Pr mm00 to ensure that the trip doesn't occur the next time the drive is powered up.
PSU Internal power supply fault
The PSU trip indicates that one or more internal power supply rails are outside their limits or overloaded.

Recommended actions:
• Remove keypad from the drive and perform a reset
• 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
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 the drive
9
• Remove control connections from the drive and perform a reset
• Remove any option modules and perform a reset
• Remove encoder connection and perform a reset
• Provide an external + 24 V power supply on Control Terminal 2 of the drive
• Permanent trip, hardware fault within the drive – return the drive to the supplier
Resistance Measured resistance has exceeded the parameter range
The Resistance trip indicates that the measured motor stator resistance during an autotune test has exceeded the
maximum possible value allowable for the drive in Stator Resistance (B34)
Recommended actions:
• Check the motor phase to phase resistance at the drive terminals
• Check the motor phase to phase resistance at the motor terminals
33
• Ensure the drives output stator resistance measurement for the motor falls within the range of the drive model
• Check the motor power cable connections
• Check the integrity of the motor stator winding using a insulation tester
• Select a suitable drive model for the motor
• Replace the motor
Slot App Menu Application menu Customization conflict error
The Slot App Menu trip indicates that more than one option slot has requested to customize the application menus S, T and
U. The sub-trip number indicates which option slot has been allowed to customize the menus.
216
Recommended actions:
• Ensure that only one of the Application modules is configured to customize the application menus S, T and U.
