3.2.4.1 Defined measuring units
Basic units are defined measuring units in the servo drive controller that typically characterise physic-
al properties. These units cannot be changed by the user.

3.2.4.2 Configurable measuring units ("user unit")
Configurable units adapted to the respective application by the user are typically required for motion
variables. They generally refer to the output-side motion variables. The conversion of these user units
can be performed only in the "Pre-operational" state and requires a reinitialisation of the servo drive.
As a result, all pertinent parameters in the servo drive are converted to the new user unit. The control-
