parameter (#320004 Machine lock rapid) as the automatic operation speed during machine
lock.
• Command speed
: Operation is carried out at the feedrate commanded in the program.
Thus, the operation time is the same as the actual machining time.
• Machine lock speed : Movement commands are processed at the high speed of 60m/min.,
and dwell time, etc., is ignored. Thus, program checks, etc., can be
carried out quickly.
(The machine lock rapid speed can be set in the parameter 120072.)
