Explanation of Operation

The motor executes reciprocating movements using the 1-speed positioning operation.
The motor can execute also the DOG type mechanical zero return operation and JOG operation.
Do not put the load on the motor for safety reasons when you confirm the operation according to this program
example.

10.2.1 DOG type mechanical zero return operation

1) When X006 (DOG type mechanical zero return operation start) in the PLC main unit is set to ON, the
motor starts the DOG type mechanical zero return operation in the current value decreasing direction.
2) When the DOG input turns ON, the motor decelerates to the zero return speed (creep).
3) When the zero-point signal is input for 3 counts after the DOG input turns OFF again, the motor stops, the
zero-point address "0" is written to the current address, and the CLR signal is output.
