Braking Module

A Braking Module and the matching braking resistor are needed by the drive when it brakes or needs to be stopped for a specific reason, e.g. for an EMERGENCY STOP. Large fans which are caused to rotate by air flow are a typical application. In such instances, it is important to consider operating states which could result in speeds in excess of the desired maximum speed but also the possibility of reversal of rotational direction during restart from standstill. A braking unit is also required if the fan must be brought to a standstill within a defined time period.

The Braking Module houses the power electronics and the associated control circuit. The supply voltage for the electronics is taken from the DC .

During operation, the DC power is converted into heat loss in an external braking resistor.

The activation threshold of the Braking Module can be adjusted by means of a switch. The braking power values indicated in the technical specifications apply to the upper activation threshold.

Braking Modules are only available for line voltages from 380 V to 480 V 3 AC:

The Braking Module is designed for installation in the control cabinet. It must always be mounted vertically.

A Braking Module is assigned its own dedicated braking resistor. The Braking Module is connected to the DC by means of flexible cables.

The Braking Module has the following interfaces as standard:

• DC connection
• Connection for braking resistor
• 1 digital input (inhibit Braking Module/reset error)
• 1 digital output (Braking Module faulty/ready)

A switch is provided for adjusting the activation threshold.
