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 or
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.

Wiring
When the GSK980TDi matches with the GS-L series servo drive; the bus then can be connected
regardless of the special cable.

Function description

defined by the standard PLC program

①
When the Cs function of the tapping spindle is invalid, the system is switched into the rigid
tapping state instead of switching the spindle servo speed/position in executing M29, defaults the
spindle servo to be the position control state.
②
When Cs function of the tapping spindle is enabled, the spindle servo for the tapping is switched
into the position control state and the system is switched into Cs contour control state.
③
Before M29 switch, the tapping spindle is permitted to the spindle mode or Cs contour control
mode. After the rigid tapping return, the tapping spindle returns to the previous control mode.
④
When the system is in the rigid tapping state, the manual movement tapping spindle cannot be
performed.
⑤
The rigid tapping state is cancelled in reset or emergency stop.
⑥
In M29, when the 1
st
or the 2
nd
spindle is currently used, it is switched into the rigid tapping state.
In rigid tapping, a spindle should be selected firstly to execute the rigid tapping interpolation. After
the spindle is switched into the rigid tapping state, the spindle switch is invalid.
⑦
After M29 is execute, M20 and the tapping command in the same block are executed to clamp
the spindle before drilling or tapping.
