5.2.1.1 Description

A Braking Module (and an external braking resistor) is required in certain cases when the drive is to be

braked or brought to a standstill (e.g. EMERGENCY SWITCHING-OFF Category 1). The Braking Module

contains the power electronics and the associated control.

The supply voltage for the electronics is taken from the DC link.

During operation, the DC link energy is converted to heat loss in an external braking resistor.

A mounting slot is provided in the Power Module.

Design

The Braking Module in chassis format is installed in a slot within the Power Module and force-cooled by its

fan. The Braking Module is connected to the DC link by means of flexible cables, which are supplied as

standard.
