Before performing the home position return, make sure that the limit switch
operates.
Check the home position return direction. An incorrect setting will cause a
reverse running.
Check the input polarity of the proximity dog. Otherwise, it may cause an
unexpected operation.
16.7.1 Outline of home position return
A home position return is performed to match the command coordinates with the machine coordinates.
Under the incremental method, every time switching on the input power supply, you have to perform the
home position return. Contrastingly, in the absolute position detection system, once you have performed the
home position return at machine installation, the current position will be retained even if the power supply is
shut off. Thereafter, the home position return is unnecessary when the power supply is switched on.
This section shows the home position return methods of the driver. Select the optimum method according to
the configuration and uses of the machine.
This driver has a home position return automatic retract function. When the machine stops on or beyond the
proximity dog, this function automatically backs the machine to the proper position and then performs the
home position return. Manually moving the machine by the JOG operation or others is unnecessary.
