5-2-2 List of warnings
When a warning occurs, a warning No. will appear on the NC monitor screen and with the LEDs on the
front of the drive unit. Check the warning No., and remove the cause of the warning by following this
list.
Drive unit warnings
No. Alarm name Warning details Reset
A9 Orientation feedback error warn Retrying during an orientation feedback error. *
E1 Overload warning The overload detection level is 80% or more. *
E4 Parameter error warning A parameter exceeding the setting range was set. *
E7 In emergency stop state Emergency stop was input. *
(Note 1) Spindle motor does not stop when the warning occurs.
(Note 2) When an emergency stop is input, spindle motor decelerates to a stop. However, if the machine ready complete input
signal remains ON, the operation after a stop differs according to the SP192 setting.
SP192=0 or 1: After a stop. the external contactor of CV is turned OFF after a period of time.
SP192=2 or 3: The external contactor of CV has been turned ON after a stop.
