Braking Module in booksize format

A Braking Module and the matching external braking resistor are required to bring drives to a controlled standstill in the event of a power failure (e.g. emergency retraction or EMERGENCY STOP category 1) or limit the DC link voltage for brief periods of generator operation, e.g. when the regenerative feedback capability of the Line Module is deactivated. The Braking Module includes the power electronics and the associated control circuit. During operation, the DC link energy is converted into heat loss in an external braking resistor. Braking Modules function autonomously.

Braking Modules in booksize format can also be used for rapid discharge of the DC link.

Дизайн



The Braking Module in booksize format features the following connections and interfaces as standard:

  • 2 DC link connections via integrated DC link busbars
  • 2 electronics power supply connections via integrated 24 V DC bars
  • Terminals for connecting the braking resistor
  • 2 digital inputs (disable Braking Module/acknowledge faults and rapid discharge of DC link)
  • 2 digital outputs (Braking Module disabled and prewarning – I × t monitoring)
  • 2 PE (protective earth) connections

The status of the Braking Module is indicated via two 2‑color LEDs.
