Full servo control mode

The pulse motor is servo-controlled to reduce the holding current (standstill current that flows after completion

of positioning).

Although the exact degree of current reduction varies depending on the actuator model, load condition, etc.,

the holding current decreases to approx. one-half to one-fourth.

Since the servo remains on, no position deviation occurs.

The actual holding current can be checked in the current monitor screen of the PC software.

To enable this mode, set “4” in this field.
