PAd Keypad has been removed when the drive is receiving the speed reference from the keypad
Install keypad and reset
34
Change speed reference selector to select speed reference from another source
PLL Err Phase Lock Loop cannot lock to the auxiliary supply
174 Check auxiliary supply is stable
PS Internal power supply fault
Remove any Solutions Modules and reset
5
Hardware fault - return drive to supplier
PS.10V 10 V user power supply current greater than 10 mA
Check wiring to terminal 4
8
Reduce load on terminal 4
PS.24V 24 V internal power supply overload
The total user load of the drive and Solutions Modules has exceeded the internal 24 V 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 load and reset
• Provide an external 24 V >50 W power supply
• Remove any Solutions Modules and reset
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 back to the power down parameter set that was last saved successfully.
37
Perform a user save (Pr xx.00 to SAVE and reset the drive) or power down the drive normally to ensure this trip does or occur the
next time the drive is powered up.
SAVE.Er User save parameters in the EEPROM are corrupt
Indicates that the power was removed when user parameters were being saved.
36
The drive will revert back to the user parameter set that was last saved successfully.
Perform a user save (Pr xx.00 to SAVE and reset the drive) to ensure this trip does or occur the 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 cable for damage

Replace cable
Replace keypad
SL AC input phase loss
Ensure all three SCR bridge supply phases are present
170
Check input voltage levels are correct (at full load)
