12.3 Drive objects
A drive object is a self-contained software function with its own parameters and, if
necessary, its own faults and alarms. Drive objects can be provided as standard (e.g. I/O
evaluation), or you can add single (e.g. terminal board) or multiple objects (e.g. drive
control).

The drive control handles closed-loop control of the motor. At least 1 Motor Module and
at least 1 motor and up to 3 sensors are assigned to the drive control.
Various types of drive control can be configured (e.g. servo control, vector control, etc.).
Several drive controls can be configured, depending on the performance of the Control
Unit and the demands made on the drive control system.
The I/Os on the Control Unit are evaluated within a drive object. High-speed inputs for
probes are processed here in addition to bidirectional digital I/Os.
