Calculation of the position encoder gearbox factor C02522

and C02523

Please note that, when the number of encoder increments in the numerator of the following

formula is indicated, the value with decimal places must be given whereas, in the numerator, the

integer (INT = integer) is used for purposes of calculation:

[6-5] Determination of the position encoder gearbox factor of linear distance measuring devices

Example: Position encoder feedback with a laser distance measuring device

The current position of a positioning unit is detected with a laser distance measuring device (e.g.

»DME5000«) with a Hiperface® interface. A graduation of 0.1 mm has been parameterised in the

distance measuring device.

The positioning unit is moved by 848.23 mm in an axial direction for each revolution of the slip-free

drive roll. The current motor speed is detected by a resolver.
