Restrictions
• Always limit the servomotor torque after the speed reaches the speed set in [Pr.47] Creep speed. Otherwise the servomotor
may be damaged when the workpiece hits to the stopper. (

• Use an external input signal as a zero signal.
• The OPR retry function cannot be used for Stopper method 3.
Precautions during the operation
• If a zero signal is input before the workpiece stops at the stopper, the workpiece stops at that position and the position is set
as an OP. In this case, no error will occur.
• When the machine OPR has been stopped by a stop signal, perform the machine OPR again. If Restart command is turned
on after the stop by a stop signal, OPR restart not possible (Error code: 1946H) occurs.
