S1 - Threshold Switch - Siemens SINAMICS S120 Manual

The signals of terminal block -X21 are factory-routed to customer interface -X55 (maximum
connectable cross section: 2.5 mm
● Jumper from -X21:2 to -X55-X132:14 (ground)
● Jumper from -X21:3 to -X55-X132:12 (DI/DO14)
● Jumper from -X21:5 to -X55-X132:1 (DI4)
● Jumper from -X21:6 to -X55-X132:9 (DI/DO12)
Note
Applying a high signal level to "DI inhibit input" inhibits the Braking Module. On a falling
edge, pending error messages are acknowledged.
The "DO fault output" signal can be used for evaluation in the Control Unit.
On the "+24 V" signal, 24 V DC must be provided by the customer to supply the Braking
Module.
Commissioning/parameterization
If a Control Unit is not being used (option K90/K95), then the four signals of terminal block -
X55-X132 must be wired to the corresponding Control Unit or to the customer interface -X55.

S1 - Threshold switch

The response threshold at which the Braking Module is activated and the DC link voltage
generated during braking is specified in the following table.
Only actuate the threshold switch when the device is switched off
The threshold switch position may be changed only when the Basic Line, Smart Line,
Active Line, or Motor Module are switched off and the DC link capacitors are discharged.
