POINT
If a stop is executed by turning ON the stop command (M1800+20n) during a
zeroing operation, re-execute the zeroing operation.
If the stop command came ON after the proximity dog came ON in the zeroing
operation, first retract to a position before the point where the proximity dog
comes ON using JOG operation or positioning, and then execute the zeroing
operation again.
