Position Control
Position control is used to input a pulse train reference from the host controller to the SERVO-
PACK to move to a target position. The position is controlled with the number of input pulses,
and the speed is controlled with the input pulse frequency. Use position control when position-
ing is required.
You set the control method to position control in Pn000 = n.
X
(Control Method Selection).
