(9) Acceleration/deceleration
mode
x This field is not used for this controller.
The factory setting is “0.”
(10) Incremental x This setting defines whether to use the absolute mode or incremental mode.
The factory setting is “0.”
0: Absolute mode
1: Incremental mode
(11) Command mode x This field is not used for this controller.
The factory setting is “0.”
(12) Standstill mode x This setting defines the power-saving mode to be applied when the actuator is
standing by after completing the positioning to the target position set in the
“Position” field for the applicable position number.
0: All power-saving modes are disabled. * The factory setting is “0: [Disable].”
1: Automatic servo-off mode. The delay time is defined by parameter No. 36.
2: Automatic servo-off mode. The delay time is defined by parameter No. 37.
3: Automatic servo-off mode. The delay time is defined by parameter No. 38.
4: Full servo control mode
Full servo control mode
The pulse motor is servo-controlled to reduce the holding current.
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.
Automatic servo-off mode
After positioning is completed, the servo will turn off upon elapse of a specified time.
(Since no holding current flows, the power consumption decreases.)
When the PLC issues the next movement command, the servo will turn on and the actuator will start moving.
