If you use an encoder pulse output with this linear encoder, the setting range of the encoder output resolution
(Pn281) is restricted. Refer to the following section for details on the encoder output resolution (Pn281).

Resolution
You can calculate the resolution that is used inside the SERVOPACK (i.e., the travel distance per
feedback pulse) with the following formula.
Resolution (travel distance per feedback pulse) =
The SERVOPACK uses feedback pulses as the unit to control a Servomotor.
