Fig. 13.35 Configuration of absolute position system
[1] Setting for absolute positions
When constructing an absolute position system, use a servomotor with absolute
position detector.
It is also necessary to install a battery for retaining the location of the OPR in the
servo amplifier. When an absolute position detector is installed, the "Absolute
position detection system (PA03)" is selected "1: Valid" in the amplifier setting for
the servo parameters (basic setting).
