SECTION 7 FIXED CYCLES
8-20. M-tool spindle Interlock Release Function (optional)
Usually, an attempt to rotate the M-tool spindle while the C-axis is not in the joined state causes an
alarm. However, using the M-tool spindle interlock release M code in the optional operation time
reduction function allows rotation of the M-tool even if the C-axis is not in the joined state.
M-tool spindle interlock M codes:
•
When M153 is designated, M13 and M14 commands are effective regardless of the C-axis
joining state.
•
When the control is reset, M152 (interlock ON) is effective.
•
When the power is turned on, M152 (interlock ON) is effective.
8-21. Other Remarks
•
No incremental data can be specified during fixed cycle mode operation.
•
After the programmed fixed cycle is completed, the C-axis is in the unclamped state and the M-
tool is rotating (M146 and M13 modes). Specify M147 and M12, if necessary.
•
If the pattern is repeated by the Q command in a fixed cycle, the Q
2
sequence is executed after
the C-axis has rotated if the cycle start point is selected as the return point.
M152 : M-tool spindle interlock release cancel (interlock ON)
M153 : M-tool spindle interlock release (interlock OFF)
