Cautions on the motor position upon power-ON
The motor working range is determined depending on the motor position upon power-ON.
(Operation example with a 23 bit absolute encoder)
(1) When the power-ON position is as shown in the figure below, the motor working range is the single-turn
data range from the power-ON position.
(2) When the power is turned off at the position in Figure (1) and then turned on again after the motor is
moved to the position in the figure below, the motor working range will be changed.
(3) If the power is turned on when the power-ON position is near the limit of the motor working range, the
motor working range is exceeded if the motor operates even if only slightly, causing Err34.1 "Single-turn
absolute working range error protection".
