Pairing Control Units and Power Units

4.4
Prerequisite:
Control units and power units must be paired to make the system fully functional. Pairing the units establishes safe internal
communication between the units. The pairing may need to be done before starting parameterization. By default, the pairing of the
units for new drives is done at the factory.
A factory reset also resets the pairing.
After performing a factory reset, the control units and power units must be paired again to make the system fully functional.
l
The pairing is done in MyDrive® Insight.
1. In MyDrive® Insight, navigate to Setup & Service > Functional safety > Safety configuration > System module pairing.
