SG Fault and Error Codes
Errors are sensed by the SG controller. The left display shows Err.
Faults are sensed by the motor driver. The left display shows FLt.
Alarms are sensed by the motor driver. The left display shows ALr.
To clear an error requires the condition be resolved (correct wiring...) and cycle the e-stop.
To clear fault requires the condition be resolved (correct wiring...), press the reset key on the drive front
panel, and cycle the e-stop. If e-stop is cycled long enough the drive will power down and that will clear
the fault too.
Alarms clear as the condition that caused them disappears (the over torque is relieved...).
