Integration
The control and feedback signal regarding the switching state of
the SBA relay is realized via terminals of the Control Interface
Module (CIM). The excitation coil of the holding brake is con-
nected directly at the SBA.
For the SINAMICS S120 units, chassis format, the brake supply
voltage must be connected externally at the SBA.
