PAd Keypad has been removed when the drive is receiving the speed reference from the keypad
34
Install keypad and reset
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
5
Remove any Solutions Modules and reset
Hardware fault - return drive to supplier
PS.10V 10 V user power supply current greater than 10 mA
8
Check wiring to terminal 4
Reduce load on terminal 4
PS.24V 24 V internal power supply overload
9
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
37
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.
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
36
Indicates that the power was removed when user parameters were being saved.
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
30
Reinstall the cable between the drive and keypad
Check cable for damage
Replace cable
Replace keypad
SL AC input phase loss
170
Ensure all three SCR bridge supply phases are present
Check input voltage levels are correct (at full load)
SLX.dF Solutions Module slot X trip: Solutions Module type installed in slot X changed
204,209,214 Save parameters and reset
SLX.Er Solutions Module slot X trip: Solutions Module in slot X has detected a fault
202,207,212
Feedback module category
See the Diagnostics section in the relevant Solutions Module User Guide for more information.
SLX.HF Solutions Module slot X trip: Solutions Module X hardware fault
200,205,210
Ensure Solutions Module is installed correctly
Return Solutions Module to supplier
SLX.nF Solutions Module slot X trip: Solutions Module has been removed
203,208,213
Ensure Solutions Module is installed correctly
Reinstall Solutions Module
Save parameters and reset drive
SL.rtd Solutions Module trip: Drive mode has changed and Solutions Module parameter routing is now incorrect
215
Press reset.
If the trip persists, contact the supplier of the drive.
SLX.tO Solutions Module slot X trip: Solutions Module watchdog timeout
201,206,211
Press reset.
If the trip persists, contact the supplier of the drive.
S.Old The maximum power the over voltage suppressor can handle has been exceeded
171
Check the recommended line reactors are installed
Check the recommended external suppressor resistor is installed
