6.3 Fault and Warning Messages
6.3.1 Error messages
Any errors that occur are shown in coded form by an error number in the LED display on the front panel. The
servo amplifier reaction depends on the fault and on the setting of parameter ACTFAULT. Faults can be reset by
hardware reset of the servo amplifier or depending on the fault (ERRCODE) by ASCII command CLRFAULT.
