7.6.9. Gear factor: numerator
This parameter is only taken into account when gear factor functionality is active.
When using a reduction gear (n2 < n1) the numerator of the gear factor is larger than the denominator.
Note:
For the “numerator“ the following restrictions apply:
EAL580 MT encoder ST13 MT16, optical: numerator <= 8192
EAL580 MT encoder ST18 MT13, optical: numerator <= 4096
EAM580 MT encoder ST14 MT16, magnetic: numerator <= 16384
7.6.10. Gear factor: denominator
This parameter is only taken into account when gear factor functionality is active.
When using a step-up gear (n2 > n1) the denominator is larger than the numerator.
7.6.11. Gear factor: parameterization
Valid combinations of numerator, denominator and total measuring range result from the formula noted
below. The parameter „measuring units per revolution“ must not exceed the maximum allowed values of the
encoder. These values are different depending on the type of the encoder.
