7.2.2 Full-scale Operation
We provide energy-saving modes to reduce power consumption in situations where the actuator remains standstill for
a long period at a standby position.
You can also select the status of position complete signal to be applied if the servo turns off or “position deviation”
occurs while the actuator is standing still after completing positioning.
Use these functions after confirming that they will not present problems to any part of your system.
z PIO pattern = 2 or 3 [16 points]
Saving energy when the actuator stands by for a long time after the power has been turned on
In this condition, you can select full servo control using parameter No. 53 (Default standstill mode). (This setting is not
affected by the value in the “Standstill mode” field of the position table.)
o For details, refer to 5.3, “Power-saving Modes at Standby Positions” and 8.2.2, “Parameters Relating to the
Actuator Operating Characteristics.”
z PIO pattern = 0 [8 points]
Power saving when the actuator stands by for a long time after the home return effected by the HOME
input signal
In this condition, you can select one of two modes based on the value of 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
o For details, refer to 5.3, “Power-saving Modes at Standby Positions” and 8.2.2, “Parameters Relating to the
Actuator Operating Characteristics.”
z Common to all PIO patterns
Saving energy when the actuator stands by for a long time at the target position
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
o For details, refer to 5.3, “Power-saving Modes at Standby Positions” and 8.2.2, “Parameters Relating to the
Actuator Operating Characteristics.”
Output mode of position complete signal
You can select the status of position complete signal to be applied if the servo turns off or “position deviation” occurs
while the actuator is standing still after completing positioning.
This setting uses parameter No. 39. Consider the characteristics of the control you need and select an appropriate
mode.
o For details, refer to 8.2.3, “Parameters Relating to the External Interface.”
