(10) Incremental command
 This field defines whether the position is specified in the absolute mode or
incremental mode.
The factory setting is “0.”
0: Absolute mode
1: Incremental mode
Warning: On the solenoid valve mode 2 [3-point type], make sure the position is specified in the absolute
mode. If it is specified in the incremental mode, the position date error (OA2) will generate.
(11) Command mode
 This field is not used for this controller.
The factory setting is “0.”
(12) Standstill mode
 Set a desired power-saving mode to be applied while the actuator stands by
after completion of positioning. To save energy when the actuator stands by
for a long period of time, this controller provides a mode in which to reduce
the power consumption while the actuator is at standstill.
The factory setting is “0” (disabled).
0: Power-saving mode is disabled
1: Automatic servo-off mode, with the delay time defined by parameter No. 36
2: Automatic servo-off mode, with the delay time defined by parameter No. 37
3: Automatic servo-off mode, with the delay time defined by parameter No. 38
Automatic servo-off mode
After positioning is completed, the servo will turn off automatically upon elapse of a
specified time.
(Power is not consumed because holding current does not flow.)
When the next movement command is received from the PLC, the servo will turn on and
the actuator will start moving.

Green LED (SV) blinks.
T: Delay time (seconds) after positioning is completed until the servo turns off

When the setting is 1: T corresponds to the value set in parameter No. 36.
When the setting is 2: T corresponds to the value set in parameter No. 37.
When the setting is 3: T corresponds to the value set in parameter No. 38.
