12.3.1
Mechanical zero return
X-axis
1) When turning X006 "X-axis mechanical zero return command" to ON at the PLC main unit, DOG type
mechanical zero return operation starts in the current value decrementing direction.
2) When turning the DOG ON, the operation decelerates to the zero return speed (creep).
3) When turning the DOG OFF, the operation stops at the zero-phase signal of the motor, and the
mechanical zero-point address is stored to the current value. (zero-point signal count: 1 time)
Y-axis
1) When turning X016 "Y-axis mechanical zero return command" to ON at the PLC main unit,
DOG type
mechanical zero return operation starts in the current value decrementing direction.
2) When turning the DOG ON, operation decelerates to the zero return speed (creep).
3) When turning the DOG OFF, the operation stops at the zero-phase signal of the motor, and the
mechanical zero-point address is stored to the current value. (zero-point signal count: 1 time)
12.3.2
JOG operation
X-axis
• When turning X004 "X-axis forward rotation JOG" to ON at the PLC main unit, the JOG operation starts in
the current value incrementing direction.
• When turning X005 "X-axis reverse rotation JOG" to ON at the PLC main unit, the JOG operation starts in
the current value decrementing direction.
Y-axis
• When turning X014 "Y-axis forward rotation JOG" to ON at the PLC main unit, the JOG operation starts in
the current value incrementing direction.
• When turning X015 "Y-axis reverse rotation JOG" to ON at the PLC main unit, the JOG operation starts in
the current value decrementing direction.
