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).
Figure 6-3 Drive objects
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.
Optionally installed drive objects
● Option board evaluation
A further drive object handles evaluation of an installed option board. The specific method
of operation depends on the type of option board installed.
● Terminal Module evaluation
A separate drive object handles evaluation of the respective optional Terminal Modules.
