6.6. Scanner abnormality monitoring function (Yaskawa head only)
* This function is available when using the remote laser with a Yaskawa Control head.
This function monitors errors from the galvano driver for the head so that the system can
issue alarms. It also monitors the deviation between the motor feedback pulse from the
galvano driver and the command pulse; it issues an error if there is an abnormal
deviation. This function can be controlled with the following S1E parameters.
