Connection

4.2 Connecting the Braking Module

Digital inputs/outputs X21

Table 4- 3

Terminal block X21

Terminal

Max. connectable cross-section 1.5 mm

DI: digital input; DO: Digital output

Note

When the Braking Module is installed, the individual terminals on its X21 terminal block are

positioned as follows: terminal "1" is at the rear, terminal "6" at the front.

Note

Applying a high signal to terminal X21.3 inhibits the Braking Module. With a falling edge,

pending fault codes are acknowledged.

Threshold switch

The response threshold at which the Braking Module is activated and the DC link voltage

generated during braking are specified in the following table.

The threshold switch must only be used when the Power Module is switched off and the DC

link capacitors are discharged.
