Sinamics_SLM_Config

"The Smart Line Module (5/10kW) is controlled using the -X21, -X22 terminal block.
A connection to the Control Unit using DRIVE-CLiQ is not present. A detailed function description for the individual signals and control/status words is contained in the SINAMICSS S120/S150 List Manual.

A control of the line contactor by the Smart Line Module or in conjunction with the Control Unit is not provided. If, however, a line contactor is used, it must be switched with a PLC or hardware control, for example. See also Section Safety Integrated and Section Line Contactor Control.

If the Smart Line Module has been switched on, the DC link has been precharged and no faults are present, the unit uses the "Ready" digital output to signal the "infeed ready" status.

This signal must then be fed appropriately to the Control Unit using an external interconnection.

The Control Unit forwards the "infeed ready" signal to the Motor Modules to enable them (see above). This ensures that the Motor Modules can be started only when the DC link is operating correctly. The Motor Modules will be disabled immediately in case of faults, etc."
