15.1 Positioning Unit Operation if an Error Occurs
15.1.1 If the Positioning Unit ERR LED Lights
When starting (stopped)
If a set value error occurs when the positioning unit is started (stopped), the various operations will not
begin. This applies to E point control, P point control, home return, JOG operation, JOG positioning
operation and pulser operation, none of which will be initiated.
During P point control operation or JOG operation
If a set value error occurs during P point control operation or during JOG operation, or if a limit error
occurs during E point control, P point control, home return, JOG operation, JOG positioning operation or
pulser operation, the positioning unit interrupts any operation currently in progress, and enters the
“deceleration stop” status.
Reference:
When a set value error occurs or a limit error occurs, the error clear flag should be turned OFF, ON, and
then OFF again. Operation cannot be restarted until the error has been cleared.
Operation continues on other axes where the set value error has not occurred.
