„ Feedback Resolutions of Linear Scale
Calculate the electronic gear ratio with the values in the following table.
Note: Pn282 is not valid when the linear scale is directly connected to the SERVOPACK and a serial converter unit is not
used. Check the linear scale pitch on the Un084 and Un085 monitors.
∗1. Models for serial converter units.
∗2. When using the encoder pulse output with these linear scales, the setting range of Pn281 is restricted. For details,
refer to 4.4.5 Setting Encoder Output Pulse.
∗3. Model for sensor head with interpolator.
∗4. Model for interpolator.
∗5. Model for interface unit by Heidenhain.
∗6. For details on this linear scale, contact Mitutoyo.
Refer to the manuals for the linear scale and the serial converter unit for details on the scale pitch and the num-
ber of divisions on the linear scale.

Electronic gear ratio setting range: 0.001 ≤ Electronic gear ratio (B/A) ≤ 4000
If the electronic gear ratio is outside this range, a parameter setting error 1 (A.040) will
be output.
