Transfer of encoder data
Data is transferred via bi-directional communication in a normal condition while power is supplied. When the driver
control power supply is turned OFF and the driver enters the battery backup mode, communication stops.
Output shaft single revolution absolute model (Option)
With the standard actuator, when it continues to rotate in just one direction, the absolute encoder eventually
exceeds the number of revolutions that can be detected with multi-revolution detection and it becomes impossible
to manage position information accurately.
With the output shaft single revolution absolute model, each time the output shaft turns through single revolution,
the cumulative multi revolution counter is cleared to 0. This is how position information is accurately managed
when the shaft continuously turns in just one direction.
