For simple absolute type, set how long the encoder position information is to be retained after
the power to the controller is turned OFF. The setting can be selected from 4 phases and as
the motor rotation speed gets slower, the time to retain the position information gets longer. In
the case that there is a possibility that the slide or the rod of the actuator that transports the
work may be moved by an external force, follow the table below and calculate
(Note 1)
the
number of rotation from the moved speed and set this parameter to the value faster than this
value. If the motor rotation setting value exceeds the set value, the position information will
be lost.
