6. SERVO MOTOR DRIVING
6 - 25
(d) Method -4 and -36 (stopper type home position return)
POINT
Since the workpiece collides with the mechanical stopper, the home position
return speed must be low enough.
The following figure shows the operation of Homing method -4. The operation direction of Homing
method -36 is opposite to that of Homing method -4.

Note 1. When Method -4 is set, the torque limit value of Positive torque limit value (60E0h) is applied. When Method -36 is set, the
torque limit value of Negative torque limit value (60E1h) is applied.
2. If the torque limit value is reached, TLC remains on after the home position return is completed.
