7 CONTROL SUB FUNCTIONS
7.2 Sub Functions Specific to Machine OPR
Movement speed during the OP shift
When the OP shift function is used, set the movement speed during the OP shift in [Pr.56] Speed specification during OP shift.
Select the movement speed during the OP shift from [Pr.46] OPR speed or [Pr.47] Creep speed. Set the speed in [Pr.56]
Speed specification during OP shift.
The following figures show the movement speed during the OP shift when the machine OPR is performed using the near-
point dog method.
■
OP shift operation at the speed set in [Pr.46] OPR speed (when [Pr.56] Speed specification
during OP shift is 0)
■
OP shift operation at the speed set in [Pr.47] Creep speed (when [Pr.56] Speed specification
during OP shift is 1)
Control precautions
• OPR complete flag ([Md.31] Status: b4), [Md.20] Current feed value, [Md.21] Machine feed value, and [Md.26] Axis
operation status are set after the OP shift operation is completed. OPR request flag ([Md.31] Status: b3) is reset after the
OP shift operation is completed.
• The value set in [Pr.53] OP shift amount is not added in [Md.34] Movement amount after near-point dog ON. The movement
amount immediately before the OP shift operation, considering the amount when the near-point dog is on as 0, is stored.
For the stopper method (1, 2, 3), the movement amount is not changed from 0.
• When using the OP shift function with the stopper method (1, 2, 3) selected for the OPR method, configure the OP shift
operation in the opposite direction of the OPR direction. Shifting in the OPR direction is not possible due to a mechanical
stopper in the OPR direction.
