/WARN (Warning Output) Signal
Both alarms and warnings are generated by the SERVOPACK. Alarms indicate errors in the
SERVOPACK for which operation must be stopped immediately. Warnings indicate situations
that may results in alarms but for which stopping operation is not yet necessary.
The /WARN (Warning) signal indicates that a condition exists that may result in an alarm.
Note: You must allocate the /WARN signal to use it. The parameters that you use depend on the allocation method.
Refer to the following section for details.
