② When SLQP=1, SLSP=0, NYQP=1, CCHU=1, CNC chooses outer chuck mode, and chuck
in-position signal detecting is active:
DOQPS: chuck clamping output; WQPJ: clamping in-position signal;
DOQPJ: chuck releasing output; NQPJ: releasing in-position signal.
DOQPJ and DOQPS output high resistance at power on, when CNC detects that the chuck input
signal DIQP is active for the 1
st
time, DOQPS is connected to 0V and chuck is clamped.
After M12 is executed, DOQPS (CN62.14) outputs 0V, DOQPJ(CN62.13) outputs high
resistance, chuck is clamped and CNC waits for WQPJ signal to be in-position.
After M13 is executed, DOQPJ (CN62.13) outputs 0V, DOQPS(CN62.14) outputs high
resistance, chuck is released and CNC waits for NQPJ signal to be in-position.

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
