15. ABSOLUTE POSITION DETECTION SYSTEM
(f) Data set type home position return
After jogging the machine to the position where the home position (e.g. 500) is to be set, choose the
home position return mode and set the home position with the home position return start switch
(X27) ON.
After switching power on, rotate the servo motor more than 1 revolution before starting home
position return.
Do not turn ON the clear (CR) (Y35) for an operation other than home position return. Turning it
on in other circumstances will cause position shift.

Note 1. When the data of the home position address parameter is not written from GX Developer or the like before starting the data set
type home position return program, this sequence circuit is required.
When the home position address is written in the home position address parameter, change to the following circuit.
2. Changes are stored temporarily to buffer memory at this time. An additional processing is required when changes should be
reflected to memory for OS or flash ROM. For details, refer to the positioning module user's manual.
