3.2.3 Additional hardware wiring for Smart Line Modules without DRIVE-CLiQ

For Smart Line Modules without a DRIVE-CLiQ interface, the signals of these modules must

be connected through hardware wiring with the CU320 control unit.

The following signals must be wired between the Smart Line Module (SLM) and the

CU320 control unit.

Signal SLM TB30 Comment

SLM Ready DO: X21.1 ⇨ DI: X481.1 SLM operational

Overtemperature

Prewarning

DO: X21.2 ⇨ DI: X481.3 Overtemperature

prewarning

Reset DI: X22.3 ⇦ DO: X481.5 Reset faults

The wiring using the TB30 Terminal Board on the SINAMICS S120 was realized in the table.

As an alternative to the wiring using the digital inputs of the TB30 Terminal Board, the wiring

can also be made directly at the digital inputs of the CU320 control unit.

CAUTION

Damage to the infeed.

If the operational signal of the Smart Line Module (SLM) is not wired to the control unit and

evaluated there, this can cause damage to the infeed.

Detailed information on the wiring is available in the documentation on the

SINAMICS S120 drive system available on the Internet
