274 Powerdrive F300 User Guide
Issue Number: 2
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
Rating Mismatch Power stage recognition: Multi module voltage or current rating mismatch
223
The Rating Mismatch trip indicates that there is a voltage rating or current rating mismatch in a multi-module drive system.
This trip is only applicable to modular drives that are connected in parallel. A mixture of power modules with different
voltage or current ratings within the same multi-module drive system is not allowed and will cause a Rating Mismatch trip.
Recommended action:
• Ensure that all modules in a multi-modular drive system are of the same frame size and rating (voltage and current)
• Hardware fault – Contact the supplier of the drive

These trip numbers are reserved trip numbers for future use. These trips should not be used by the user application
programs.
Resistance Measured resistance has exceeded the parameter range
33
The Resistance trip indicates that the measured stator resistance during an auto-tune test has exceeded the maximum
possible value of Stator Resistance (05.017).
The stationary auto-tune is initiated using the auto-tune function (Pr 05.012) or in open loop vector mode (Pr 05.014) on the
first run command after power up in mode 4 (Ur_I) or on every run command in modes 0 (Ur_S) or 3 (Ur_Auto). This trip
can occur if the motor is very small in comparison to the rating of the drive.
Recommended actions:
• 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
Slot4 Not Fitted Interface in slot 4 has been removed
253
The Slot4 Not Fitted trip indicates that the interface in slot 4 on the drive has been removed since the last power-up.
Recommended actions:
• Hardware fault - Contact the supplier of the drive.
Slot App Menu Application menu Customization conflict error
216
The Slot App Menu trip indicates that more than one option slot has requested to customize the application menus 18, 19
and 20. The sub-trip number indicates which option slot has been allowed to customize the menus.
Recommended actions:
• Ensure that only one of the Application modules is configured to customize the application menus 18, 19 and 20
