Operation and Troubleshooting
Keypad Operation
Display Mode (Default) Fault Mode
*NOTES:
“PLd” can be caused by a Grounded delta power system. If one input leg measures ZERO volts to ground, reduce
the setting of F051 to “0054” for operation on a “Grounded Delta”.
“SSd” can be caused by operating without a motor connected, ensure the motor is firmly connected.
“LcA, Lcc, or Lcd” indicates that the Surge absorber is damaged; see NOTE 1 on wiring diagram.
