6.1.1 Setting of periods taken until automatic servo OFF
Three periods from completion of positioning to automatic servo OFF can be set in the
following parameters in seconds [sec].
Parameter
No.
Name Unit Input range
Initial
value
36 Automatic servo-off delay time 1 sec 0 to 9999 0
37 Automatic servo-off delay time 2 sec 0 to 9999 0
38 Automatic servo-off delay time 3 sec 0 to 9999 0
6.1.2 Set of power-saving mode
Select a proper power-saving mode from the conditions below. Set the corresponding value
in the stop mode or parameter No.53 of the position table.
Selection is available from 0 to 3 for RCP6S, RCM-P6AC and RCM-P6DC.
Selection is available from 0 to 7 for RCM-P6PC.
However, selection should be made from 0 to 3 in case an actuator equipped with the
high-resolution battery-less absolute encoder is connected.
[Refer to 14) Stop mode in 3.3 Set of Position Table.]

Caution:
y
No retaining torque is provided in automatic servo OFF. Pay sufficient
attention to the setting because the actuator may be moved by external force
applied to it.
y
Do not use the automatic servo OFF if the next moving command is relative
distance specification (pitch feed). Failure to follow it may cause position shift
to occur.
y
Do not use the automatic servo OFF in pressing. If used, the pressing force is
lost.
y
Automatic Servo OFF would not function in the operation with teaching mode
of PC software.
