For Simple Absolute Type, establish the setting to define how long the position information of
the encoder is to be remained for after the power to the controller is turned OFF. Setting can be
done from four grades. Maximum number of the motor revolution due to external force during
the power is OFF is controlled by the set days. Establish the setting assuming the speed when
the work transporting parts, slider or rod, on the actuator is moved by external force during the
power being OFF. The position information will lose if the number of motor revolution exceeds
the set value. Consider safety margin when establishing the setting.
