7) Energy-Saving Function…If the energy saving function is turned active, the motor power
supply (servo) will turn off automatically to save electricity in a
certain while after a positioning is complete.
Set the time in the parameter in advance.
Parameter No. Parameter Name Initial Value Setting range
10 Auto Servo OFF Delay Time [sec] 1 0 to 9999
[Automatic Servo off]
The servo automatically turns off after a specified time once the position is complete. When the
next position is commanded, the servo will automatically turn on and execute the position. It
will save power consumption since the no current is used during servo off.
[Position Detection Output Signal Condition When Pressing Function Not used]
As long as the actuator position is in the range of the positioning width (Parameter No. 1) even
if the motor power supply (servo) is off, either of the forward position detection signal (LS0),
backward position detection signal (LS1) or intermediate detection signal (LS2) turns on in
accordance with the current position as the sensor does. Thus, if the actuator does not move
after the positioning is complete, the position detection signal is kept on.
[Positioning Complete Signal Condition When Pressing Function is used]
The motor power supply (servo) does not turn off automatically while in the pressing condition
during the pressing operation.
The servo will automatically turn off if a miss-pressing is occurred.
Turning the motor power supply (servo) off makes the positioning not completed. Thus, all of
the pressing completion signal 0 (PE0), pressing completion signal 1 (PE1) and pressing
completion signal 2 (PE2) turn off no matter where the stopped position is.
There is no holding torque during the automatic servo off. The actuator could move with an
external force. Pay attention to the interference and safety to the surroundings.
