12.6 Absolute position restoration function
!
CAUTION
An absolute position restoration by the positioning function may turn off the servo-on signal (servo off) for
approximately 60ms + scan time, and the motor may run unexpectedly. If this causes a problem, provide an
electromagnetic brake to lock the motor during absolute position restoration.
The "absolute position restoration function" is a function to restore the absolute position
of the designated axis by the absolute position detection system. By this function, the
OPR after power OFF such as instantaneous power interruption and emergency stop
is not required, and the restoration operation at site can be carried out easily.
The details of the "absolute position restoration function" are described below.
