* The encoder on the motor side is a built-in encoder and, therefore, does not have a
measuring gear unit.
The transmission ratio is always 1:1.
◆ For distance-coded measuring systems
● These machine data are not required for encoder matching (path evaluation).
However, they must be entered correctly for the setpoint calculation! Otherwise the
