6.3.2 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. option board) or multiple objects (e.g. drive control).

Standard drive objects
● Infeed: Infeed control for Active Line Module
If an Active Line Module is used for the infeed in a drive system, open-loop/closed-loop
control is implemented on the Control Unit within a corresponding drive object.
● Drive control
Drive control handles closed-loop control of the motor. 1 Motor Module and at least 1
motor and up to 3 sensors are assigned to the drive control.
● Control Unit, inputs/outputs
The inputs/outputs 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.
Properties of a drive object
● Separate parameter space
● Separate window in STARTER
● Separate fault/alarm system (for CU, VECTOR, A_INF)
● Separate PROFIdrive telegram for process data (for CU, VECTOR, A_INF)
