
Select “5” (stopper) for the home position shift amount reference signal (PA2_11). Be sure to
enter the output torque generated upon contact with the stopper, as a torque limit for
contact-stopper (PA2_23), and enter the time between contact with the stopper and completion
of homing as a Detection time for contact-stopper (PA2_22).
(i) If the home position sift amount (PA2_14) is zero, homing is finished at the stopping
position after the detection time for contact-stopper.
(ii) If the home position shift amount (PA2_14) is other than zero, the motor moves by the
home position shift amount from the stopping position after the detection time for
contact-stopper in the reverse direction to the contact stop, and homing is finished
there.
