<1> During referencing, only the position setpoint and actual value are corrected by the
same amount in each case. No compensation movement takes place.
<2> Referencing on the fly is enabled dynamically with "Enable referencing"
(binector input U675.1).
The interrupt-generating digital inputs of terminal 6 or 7 are parameterized via
MD46. Referencing is activated by the signal "Measured position value valid".
