Fig. 2-54 Chuck clamping, releasing signals are level output
As the 2
nd
chuck input is active, DOQPS outputs 0V, chuck is released. The chuck
clamping/releasing signal is output alternatively, i.e. the output is changed each chuck input signal is
active.

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.
