dog ON Outside the setting range" (error code: 22) occurs, and the OPR does not start.
In addition, if the position after the move according to "
dog ON" is close to Zero signal, the Zero signal may be misread, resulting in deviation of OP by one
servomotor rotation. Set "
after the move becomes closer to the center of Zero signals.
(b) OPR start while near-point dog is on
The operation is as follows.

(c) Outside the stroke limit range
If the workpiece moved outside the stroke limit range, the error "Outside the stroke limit range" (error code:
