• It is used in a system where the proximity dog signal cannot be used
and only external limit switch can be used.
• The travel direction is reversed at the proximity dog ON, and home
position is encoder zero point after reversal.
• This method is valid to make the home position for the load side at the
linear motors or direct drive motors use.
• It is used in a system where proximity dog signal cannot be used and
stops at the zero point of servo motor.
• Home position return operation differs by servo amplifier.
• The driver performs home position return operation autonomously
according to the settings on the driver-side.
