The function library “SINAMICS DriveLib” supports the relevant functions for controlling the SINAMICS S120. The “SINA_INFEED” function block in the function library supports the control of the SINAMICS S120 power supply module.

Before you can control the related SINAMICS S120 device through the motion control function of the SIMATIC S1500(T), the power supply module of the SINAMICS S120 must have been started, and the current drive must have received the “Supply mode” signal. If this is not the case, the drive or the technology object will have an error state and, in the worst case, the power supply module may be damaged.

How the power supply module is started and how the driver receives the “Supply mode” signal depends on the type of power supply module used:

●SINAMICS S120 power modules without DRIVE-CLIQ interface:

The power module is activated through the terminal, and the operation of the power module is through the EP terminal. The “run” signal of the power supply module is output through the RDY terminal, and this signal must be connected to the “Supply mode” signal when configuring the relevant drive.

●SINAMICS S120 power supply module with DRIVE-CLIQ interface:

The start and stop of the power supply module is configured via the 370 telegram for communication with the SIMATIC S7-1500(T). The BICO interconnection required by the 370 telegram is automatically generated in the power supply module of the drive. The “SINA_INFEED” function block in the “SINAMICS DriveLib” function library can be used to start, stop and diagnose SINAMIC S120 power modules connected via DRIVE-CLIQ.
