*1. These are reference values for setting SERVOPACK parameters. Contact the manufacturer for actual linear
encoder scale pitches.
*2. This is the model of the Serial Converter Unit.
*3. This is the model of the Head with Interpolator.
*4. This is the model of the Interpolator.
*5. 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.
The SERVOPACK uses feedback pulses as the unit to control a Servomotor.
Resolution (travel distance per feedback pulse) =
Linear encoder pitch
Resolution of Serial Converter Unit or linear encoder
Linear encoder pitch
=Distance for one cycle of the analog voltage
feedback signal from the linear encoder
