=0: Chuck clamping and releasing signals are level output
� Signal connection
The circuit of DOQPJ/DOQPS is shown in Fig. 2-52:

� Sequence
①When SLQP=1, SLSP=0, NYQP=0, CCHU=1, CNC chooses inner chuck mode, and
chuck
in-position signal detecting is active:
DOQPS: chuck releasing output; WQPJ: releasing in-position signal;
DOQPJ: chuck clamping output; NQPJ: clamping 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 1st time, DOQPJ is connected to 0V and chuck is clamped.
After M12 is executed, DOQPS (pin 14 of CN62) outputs high resistance, DOQPJ(pin 13
of
CN62) outputs 0V, chuck is clamped and CNC waits for NQPJ signal to be in-position.
After M13 is executed, DOQPJ (pin 13 of CN62) outputs high resistance, DOQPS(pin 14
of
CN62) outputs 0V, chuck is released and CNC waits for WQPJ signal to be in-position.

②When 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 1st 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 2nd 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
