Changing the PV of the Pulse Output

The present value of the pulse output can be changed by using the INI(880) instruction. To define the
present value as the origin, set the pulse output PV to 0 using the INI(880) instruction.

Application Example

Operation
Connect a Servo Drive and execute an origin search based on the Servomotor's built-in encoder phase-
Z signal and an origin proximity input signal.
Parameter Settings
• Operation Mode: 1
(Uses the Servomotor encoder's phase-Z signal as the origin input signal.)
• Origin Search at Limit Input: 0
(Sets reverse mode 0. Reverses direction when the limit input signal is input in the origin search
direction.)
• Origin Detected after Prox Input: 0
(Reads the origin input signal after the origin input signal goes OFF→ON→OFF.)
• Search Direction: CW
