5.6.1 Outline of home position return
Home position return is performed to match the command coordinates with the machine coordinates. In the
incremental system, home position return is required every time input power is switched on. In the absolute
position detection system, once home position return is done at the time of installation, the current position is
retained if power is switched off. Hence, home position return is not required when power is switched on again.
This servo amplifier has the home position return methods given in this section. Choose the most appropriate
method for your machine structure and application.
This servo amplifier has the home position return automatic return function which executes home position
return by making an automatic return to a proper position if the machine has stopped beyond or at the
proximity dog. Manual motion by jog operation or the like is not required.
