Operation explanation

• Zero return operation
1) When X006 in the PLC is turned ON, the zero return operation is stared in the decreasing
direction of the current value.
(Only when m code is OFF, the zero return operation can be started.)
2) When the jog input is turned ON, the work is decelerated to the creep speed.
3) Positioning is stopped when the zero point signal is input for one count after the dog input is
turned OFF again. The zero point address is written into the current value and the clear
signal is output.
4) The dog search function can be used depending on the start position of the zero return
operation.
(Set X002 and X003 at the forward and reverse limits respectively.)
