started.)

POINT
If a stop is executed by turning ON the rapid stop command (M1801+20n)
during a zeroing operation, re-execute the zeroing operation. If the rapid 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.
