12.10 Rules for wiring with DRIVE-CLiQ
General DRIVE-CLiQ rules
The following generally binding DRIVE-CLiQ rules must be observed to ensure safe
operation of the drive.
1. A maximum of 14 DRIVE-CLiQ nodes can be connected to one DRIVE-CLiQ line at a
2. A maximum of 8 Motor Modules may be connected to one Control Unit. For multi-axis
3. With vector U/f control, it is only permissible to connect more than 4 participants to one
4. Ring wiring of components is not permitted.
5. Double wiring of components is not permitted.
6. DRIVE-CLiQ components of unknown type within a topology are functionally not
7. In a DRIVE-CLiQ topology with a CU link and DRIVE-CLiQ connections, precisely one
8. If a CU link connection is detected, the DRIVE-CLiQ basic clock cycle 0 (r0110[0]) is set

The following criteria denote the unknown type:
– Characteristics of the component are not available.
– A deputy drive object is not defined.
– An assignment of the component to a known drive object (DO) is not defined.
