4. OPERATION AND FUNCTIONS
To always make a home position return to the same position, perform the following operation.
Once move the rotary encoder to the stroke end opposite to the home position return direction with the JOG
operation of controller, etc. and then perform a home position return.

(4) About dog type home position return when using the rotary encoder of a serial communication servo motor
The home position for when using the rotary encoder of a serial communication servo motor for the load
side encoder is at the load side Z-phase position.

Equivalent to one load side revolution
(5) About data setting type (Common to all load side encoders)
In the data setting type home position return method, pass through a scale home position (reference mark)
and the Z-phase signal of the rotary encoder, and then make a home position return.
When the machine has no distance of one motor encoder revolution until the Z-phase of the rotary encoder
is passed through, a home position return can be made by changing the parameter No.PC17 (home
position setting condition selection) setting if the home position is not yet passed through.
