6.3 Power-saving Modes at Standby Positions
This product provides 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.
The actuator stands by after completing the home return operation effected by the HOME input signal
When the actuator is in this condition, you can select a desired energy-saving mode from the available options
by setting an applicable 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.)
The actuator stands by after completing the positioning to the target position set in the “Position” field
for the applicable position number
When the actuator is in this condition, you can select a desired energy-saving mode from the available options
by setting an applicable value in the “Standstill mode” field of the position table.
(This setting is not affected by the value of parameter No. 53.)
Meanings of values set in the “Standstill mode” field of the position table and in parameter No. 53
Setting
All power-saving modes are disabled. (The actuator is completely stopped.) 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.
* Since the servo turns off once, some position deviation may occur. Do not use this function at standby
positions where position deviation will cause problem.
