homing internal driver AC servo?

Hi,

I'm using a HC-KFS13 motor with MR-J2S-10A driver, i want to control this motor by step/dir pulse system. as i see i can setup home position for driver but dont know how to return home for motor, there is only one signal "INP" to know when motor is in home position.I suppose i should use this signal like a home button, right?

If anyone has experience about Mitsubishi AC servo can help me?
Here is the driver's manual:
dl.mitsubishielectric.com/dl/fa/document...030006/sh030006j.pdf

actuatly i want to use absolute encoder of Mitsubishi driver. The home return is describe in section 15.7.3 but i dont really understand it.

If it possible i would like to use abs encoder and homing inside driver and then i can use a simple controller instead of linuxcnc also SSCII protocol

no experience with MR-J2S-A drives, but as far as i understand all the "15.7.3 Home position setting" operations are really doing is writing current motor position counters (which are named "LS" - full rev count and "1X" - with 1-rev pos on picture 15.1.1) into parameter EEPROM as "LS0" and "1X0". after that when the controller requests absolute position data (15.7.1) the drive returns current motor position subtracted with home position (LS-LS0, 1X-1X0).

so if you want to use absolute position you'll need to use that cumbersome protocol 15.7.1 to request the motor position and pass it to linuxcnc
