5.3 Power-saving Modes at Standby Positions
One general feature of pulse motors is that their holding current in standstill state is greater than AC servo motors.
Therefore, we provide energy-saving modes to reduce power consumption in situations where the actuator remains
standstill for a long period at a standby position.
Use these modes after confirming that they will not present problems to any part of your system.
Each mode produces a different level of power-saving effect. Follow the instructions provided below and select an
optimal mode appropriate for the specific standstill condition of your actuator.
z PIO pattern = Other than 0 [8 points]
The actuator stands by with the servo on after the power has been turned on
In this condition, you can select full servo control using parameter No. 53 (Default standstill mode).
Automatic servo-off control cannot be selected. If you have set 1, 2 or 3 by mistake, the setting will be ignored.
(This setting is not affected by the value in the “Standstill mode” field of the position table.)
The actuator stands by after completing the positioning to the target position set in the “Position” field for the
applicable position number
In this condition, you can select one of two modes based on the value in the “Standstill mode” field of the position
table.
(This setting is not affected by the value of parameter No. 53.)
[1] Full servo control
[2] Automatic servo-off control
z PIO pattern = 0 [8 points]
The actuator stands by after completing the home return effected by the HOME input signal
In this condition, you can select one of two modes based on the value in parameter No. 53 (Default standstill mode).
(This setting is not affected by the value in the “Standstill mode” field of the position table.)
[1] Full servo control
[2] Automatic servo-off control
The actuator stands by after completing the positioning to the target position set in the “Position” field for the
applicable position number
In this condition, you can select one of two modes based on the value in the “Standstill mode” field of the position
table.
(This setting is not affected by the value of parameter No. 53.)
[1] Full servo control
[2] Automatic servo-off control
