2.3 Setpoint /actual-value system
2.3.7 Adjustments to actual-value resolution
Calculating the ratio
The calculation of the ratio is obtained from the associated machine data and is defined for
incremental encoders as follows:
For incremental encoders with rotary axis, the following applies:
The internal pulse multiplication factor provided by the measuring system logic module is
• 2048
• 128
