z Note that the actuator moves in the negative direction with a forward pulse (forward for the motor) and
in the positive direction with a reverse pulse (reverse for the motor). (Opposite applies to folded motor
type actuators).
z When considering the forward/reverse direction, pay attention to the settings of the host controller or
connection of PP and /PP as well as NP and /NP.
* The rotation direction of the motor is indicated by setting CCW to forward, as seen from the axis edge
of the load side.

It is possible to set six types of command pulse modes by the command pulse input mode, a position
control parameter.

A forward pulse train indicates motor revolutions in the forward direction, while a reverse pulse
train indicates motor revolutions in the reverse direction.

A command pulse indicates motor revolutions and its sign indicates the rotating direction of the
motor.
