OV DC bus voltage has exceeded the peak level or the maximum continuous level for 15 seconds

- Increase the deceleration ramp (Pr 0.04).
- Decrease the braking resistor value (ensuring it stays above the minimum value).
- Check the nominal AC supply level.
- Check for voltage disturbances that could cause a rise in the DC bus voltage, such as overshoot after supply recovery from a DC drive-induced notch.
- Check motor insulation.

Drive voltage ratings:

- 200V: Peak voltage = 415V, Maximum continuous voltage = 410V
- 400V: Peak voltage = 830V, Maximum continuous voltage = 815V
- 575V: Peak voltage = 990V, Maximum continuous voltage = 970V
- 690V: Peak voltage = 1190V, Maximum continuous voltage = 1175V

If the drive is operating in low-voltage DC mode, the over-voltage trip level is 1.45 times Pr 6.46.

PAd Keypad has been removed while the drive is receiving the speed reference from the keypad

- Reinstall the keypad and reset.
- Change the speed reference selector to receive the speed reference from another source.

PH AC voltage input phase loss or large supply imbalance detected

- Ensure that all three phases are present and balanced.
- Check that the input voltage levels are correct (at full load).
- The drive will attempt to stop the motor before tripping due to phase loss. Load level should be between 50% and 100%.

PH.P Power module phase loss detected

- Ensure that all three phases are present and balanced.
- Check that the input voltage levels are correct (at full load).

PS Internal power supply fault

- Remove any Solutions Modules and reset.
- Hardware fault - return the drive to the supplier.

PS.10V 10V user power supply current greater than 10mA

- Check the wiring to terminal 4.
- Reduce the load on terminal 4.

PS.24V 24V internal power supply overload

- The total user load of the drive and Solutions Modules has exceeded the internal 24V power supply limit. The user load consists of the drive’s digital outputs, the SM-I/O Plus digital outputs, the drive’s main encoder supply, and the SM-Universal Encoder Plus encoder supply.
- Reduce the load and reset.
- Provide an external 24V >50W power supply.
- Remove any Solutions Modules and reset.

PS.P Power module power supply fail

- Remove any Solutions Modules and reset.
- Hardware fault - return the drive to the supplier.

PSAVE.Er Power down save parameters in the EEPROM are corrupt

- Indicates that the power was removed when power-down save parameters were being saved.
- The drive will revert to the last successfully saved power-down parameter set.
- Perform a user save (set Pr xx.00 to 1000 or 1001 and reset the drive), or power down the drive properly to ensure this trip does not occur next time the drive is powered up.

rS Failure to measure resistance during autotune or when starting in open-loop vector mode

- Check the continuity of the motor power connection.

SAVE.Er User save parameters in the EEPROM are corrupt

- Indicates that the power was removed when user parameters were being saved.
- The drive will revert to the last successfully saved user parameter set.
- Perform a user save (set Pr xx.00 to 1000 or 1001 and reset the drive) to ensure this trip does not occur next time the drive is powered up.

SCL Drive RS485 serial comms loss to remote keypad

- Reinstall the cable between the drive and keypad.
- Check the cable for damage.
- Replace the cable.
- Replace the keypad.
