5.4.4 Electronic Gear
5-44
The electronic gear ratio to be set can be calculated by the following equation:
Feedback Resolutions of Linear Scale
Calculate the electronic gear ratio with the values in the following table.
Models for serial converter units.
Models for heads with interpolators.
Models for interpolators.
When using the encoder pulse output with these linear scales, the setting range of Pn281 is restricted. For details,
refer to
5.3.7 Setting Encoder Output Pulse
.
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.
