10 Encoder Configuration
The maximum encoder frequency is defined with 750 kHz (at 1x edge analysis). This
corresponds to a maximum counter frequency or 1.5 MHz (at 4x edge analysis).
When selecting the encoder to install, this must be taken into consideration accordingly.
In the following table, the permissible speed in the rotary encoder for the respective
resolution based on the maximum encoder frequency can be seen.

This is only a sample of possible encoder resolutions.
With the following formulas, the highest permissible rotation speed (revolutions/min) can be
determined for an encoder with a resolution that is not listed in the table above.
