MP Function and input
MP7440 Output of M functions
Format:
Input:
0: Program stop with M06
1: No program stop with M06
Bit 1 – Modal cycle call M89
0: Normal code transfer of M89 at beginning of block
1: Modal cycle call M89 at end of block
Bit 2 – Program stop with M functions
0: Program stop until acknowledgment of the M function
1: No program stop: No waiting for acknowledgment.
Bit 3 – Switching of kv factors with M105/M106:
0: Function is not in effect
1: Function is effective
Bit 4 – Reduced feed rate in the tool axis with M103:
0: Function is not in effect
1: Function is effective
Bit 5 – Reserved
Bit 6 – Automatic activation of M134
0: M134 must be activated in the NC program
1: M134 is automatically activated when an NC program is selected.
MP7441 Error message during cycle call
Format:
Input:
0: Error message Spindle ? is not suppressed
1: Error message Spindle ? is suppressed
Bit 1: Reserved, enter 0
Bit 2 –
0: Error message Enter depth as negative is suppressed
1: Error message Enter depth as negative is not suppressed
MP7442 Number of the M function for spindle orientation in the cycles
Input:
0: No oriented spindle stop
–1: Oriented spindle stop by the NC
MP7444 Delay time for the change signals (M/S/T)
Input:
0: Change signal after complete filter run time (previous behavior)
1 = Change signal if the nominal feed rate reached the value 0 before the actual value
(formed by the filters) did.
2 = Change signal if the nominal feed rate reached the value 0 before the actual value
(formed by the filters) did, and an additional delay until the actual value reaches the time
window the first time.
MP7450 Offsetting the tool change position from MP951.x in block scan
Format:
Input:
0: Do not offset
1: Offset
MP7451.0-8 Feed rate for returning to the contour for axes 1 to 9
Input:
MP7460.x Reserved
30 – 628
