Description
MT.DEC specifies the motion task deceleration and is used by the MT.SET and MT.LOAD commands. This
parameter is a temporary value, since a motion task is only set after an MT.SET command is issued. The motion
task deceleration is further limited by the maximum allowed acceleration, DRV.DEC.
A value of 0 for MT.DEC should not be used when setting a motion task via MT.SET because this value causes
a validity check of the MT.SET command to fail.
A value of 0 for MT.DEC after an MT.LOAD command displays an empty (not initialized) motion task.
