key
of the spindle on the panel still controls the 1st spindle.
1.5. The spindle override of the 2nd spindle is fixed to 100%.
1.6. Cs axis control of two spindles can be separately switched and the current used
spindle has
no requirements, that is, when the current is the 1st(2nd) spindle, the 2nd (1st) spindle
executes the Cs switch.
� Cs control logic of the 2nd spindle
1.1. After M24 is execute, PLC→Drive sends the 2nd spindle speed/position control mode
switch
signal VP2;
1.2 Drive unit starts the switch control mode. After the switch is completed, Drive→PLC
outputs
the speed/position switch state signal VPO2;
1.3. After the PLC receives the spindle speed/position switch state signal VPO2, the 2nd
spindle
contour control switch signal CON(G127.7) is set to 1. After the system has checked the
2nd
spindle contour control switch end signal FSCSL(F144.1), M24 execution is ended. The
spindle control mode switch is ended.
2. M25 execute processes are the same those of M24.
3. M25 only cancels M24 executing the speed/position switch. Executing M25 cannot
switch the
system into the speed control mode when executing M29 switches the spindle into Cs
contour
control.
4. on the panel is only used to Cs switch of the 1st spindle.
5. Before switch, the spindle can rotate or stop. After switch, the spindle stops.
6. When the spindle is in Cs contour control mode, the spindle rotation(CW/CCW) output
is
invalid.
7. When the spindle is in the external speed control mode, the manual operation of Cs
axis is
invalid.
8. When the alarm occurs in the servo or because of the too long switch time or the reset

emergency stop appears in switch, PLC switches the spindle into the speed control state.
9. When PLC K15.6 is set to 1, the spindle contour control is disabled in emergency stop,
reset.
PLC switches the spindle into the speed control state.
10. When PLC K17.7 is set to 1, the multiple spindle function is enabled, and the system
