Target position
T: Delay time (seconds) after
positioning is completed until the
servo turns off
 Automatic servo-off delay time
This parameter defines the delay time after the positioning is completed until the servo turns off automatically,
when the “Standstill mode” field of the position table is set to “1,” “2” or “3” (automatic servo-off control enabled)
or parameter No. 53 (Default standstill mode) is set to “1,” “2” or “3”(automatic servo-off control enabled).
Meaning of settings: 1: T becomes the value set by parameter No. 36.
2: T becomes the value set by parameter No. 37.
3: T becomes the value set by parameter No. 38.
The factory setting is “0 [sec].”
 Default standstill mode
[1] If the PIO pattern is 0, 1, 2, 3 or 4, the automatic servo-off mode can be selected to save current
consumption when the actuator is standing by for a long time after completing the home return effected by
the HOME input signal.
[2] If the PIO pattern is 5, this value is treated as the setting in the “Standstill mode” field corresponding to the
applicable position number when a target position has been written to the unregistered position table.
A value of “1,” “2” or “3” must be set in parameter No. 53 in order to enable the automatic servo-off function.
The factory setting is “0 [Disable].”
Setting
All power-saving modes are disabled. 0
Automatic servo-off mode. The delay time is defined by parameter No. 36. 1
Automatic servo-off mode. The delay time is defined by parameter No. 37. 2
Automatic servo-off mode. The delay time is defined by parameter No. 38. 3
Automatic servo-off mode
After positioning is completed, the servo will turn off automatically upon elapse of a specified time.
(Since no holding current flows, power consumption will decrease.)
When the next movement command is received from the PLC, the servo will turn on and the actuator will start
moving.
Refer to the above timing chart.
