active.
③ The interlock between the chuck and the spindle
When SLQP=1, SLSP=0, M3 or M4 is active, the alarm is issued if M13 is executed and the
output is unchanged.
When SLQP=1, SLSP=0, CCHU=1, if M12 is executed in MDI or Auto mode, CNC does not
execute next code till it detects the chuck clamping in-position signal is active. When the chuck
input signal DIQP is active in Manual mode, the panel spindle CW, CCW key are inactive till it
detects the chuck clamping in-position signal is active. In spindle running or auto cycle processing,
DIQP input signal is inactive. And DOQPS, DOQPJ is held on at CNC reset and emergency stop.
2.8.15 Tailstock control
z Relevant signal (defined by standard PLC program)
DOTWJ: Tailstock forward output signal
DOTWS: Tailstock backward output signal
DITW: Tailstock input signal, DITW and BDT share a common interface.
Note: For GSK980TDc-V, can replace DITW input signal, and the diagnosis address is X0026.5.

K 1 3 SPTW SLTW
SLTW =1: Tailstock function active.
=0: Tailstock function inactive.
SPTW =1: No interlock between spindle rotation and tailstock advancing and retracting,
tailstock may be moved regardless of the spindle, or spindle may run regardless of
tailstock;
=0: Interlock between spindle rotation and tailstock advancing and retracting, tailstock
retraction disabled as spindle is running, spindle disabled if tailstock does not
advance.
