active.
③The 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
� 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: ForTAC-1002T-V, can replace DITW input signal, and the diagnosis address is X0026.5.

K 1 3 RTSC 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.
RTSC =1: External tailstock control is active when a program runs.
=0: External tailstock control is inactive when a program runs
� Signal connection
The tailstock circuit is shown in Fig. 2-55:
