Activating the Braking Module

To activate the braking module and set the operation threshold as well as hysteresis for the

braking module, proceed as follows:

1. Configure the Control Unit and the infeed unit as usual (see SINAMICS S120

Commissioning Manual with STARTER).

2. Select "VECTOR" as drive object type.

3. "U/f control" should be selected as controller structure.

4. In the parameter p1300 (open loop/closed loop control mode of operation), output the value

"15" (operation with braking resistor).

5. Select the supply voltage in the configuration dialog box.

6. Pre-allocate the supply voltage p0210 according to the infeed unit being used (e.g. for a

Basic Line Module with approx. 600 V at 400 V of supply voltage).

7. In the configuration dialog box, select "Chassis" as format.

8. Enter the value "1" in parameter p0864 (infeed unit operation) if the drive line-up is not

equipped with a Basic Line Module.

9. Select the required power unit in the configuration dialog box.

10.Terminate the configuration for the Motor Module and the resistors. Parameter input for

p1360 (Braking Module braking resistance, cold) using the expert list.
