Description: The power unit data set is assigned to a power unit using this parameter.
This unique component number is assigned when parameterizing the topology.
Only component numbers can be entered into this parameter that correspond to a power unit.

Description: Setting to activate/de-activate a power unit component.
Value: 0:

Recommendation: After inserting a component, before activating, first wait for Alarm A01317.
Caution: For a parallel connection, the following applies:
When deactivating individual power units using p0125, it is not permissible that the power units of the parallel
connection involved are connected. Infeed units should be disconnected from the line supply (for example, using a
contactor). Motor feeder cables should be disconnected. In addition, defective power units should be disconnected
from the DC link.
Notice: It is not permissible to de-activate drive objects with safety functions enabled.
Note: The activation of a component can be rejected if the component was inserted for the first time. In this case, it is only
possible to activate the component when the pulses for all of the drive objects are inhibited.
For units connected in parallel, when one of the power units is de-activated, then the enable in p7001 is withdrawn.
Re value = 0, 2:
When a component is deactivated it no longer outputs any errors.
If value = 0:
The component was completely commissioned and is deactivated using this value. It can be removed from the
DRIVE-CLiQ without any error.
If value = 1:
The component must be available for error-free operation.
If value = 2:
A component in a project generated offline and set to this value must never be inserted in the actual topology from
the very start. This means that the component is marked to be bypassed in the DRIVE-CLiQ line.
For components that comprise several individual components (e.g. Double Motor Modules), it is not permissible to
set just one subset to this value.
