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 (PBON). After switching power on, rotate the servo motor more than 1 revolution before starting home position return.

Do not turn ON the clear signal (Y35) for an operation other than home position return. Turning it on in other circumstances will cause position shift.
