Braking Devices AC-VersiBrake 230/400-6/25/30L (LP)

Function:

  • start braking via detection of motor voltage and via motor contactor (double safety)
  • overload protection
  • braking current cutoff after motor standstill
  • braking current control
  • automatic remanence time optimization
  • braking current infinitely adjustable 10-100%
  • potential-free output for motor contactor interlocking during braking; also usable to energize the star contactor during braking
  • standstill threshold adjustable; individual adaptable to different motor types

Features:

  • DC braking with one-way rectification
  • suitable for all asynchronous motors and for mono phase motors
  • controlled by microcontroller
  • easy mounting, also for retrofitting into existing plants
  • wear-resistant and maintenance-free
  • integrated braking contactor
  • printed circuit-board version with fault signalling contact
  • for snap-on mounting onto 35mm DIN rail
  • degree of protection: case version IP 20, printed circuit-board version (LP) IP 00
  • meets trade assoc. requirements for category 2 acc. to EN 954-1 acc. to the test principles of woodworking machines GS-HO-01

Typical Applications:

  • sawing machines
  • centrifuges
  • wood working machines
  • textile machines
  • conveying systems

Connection Diagram:


Functional description:

* Connection of X3, X4 will only be needed if double security for the start of braking is required.
** Connection of 6T3 is only necessary with very short standstill times of motor (<3s). If 6T3 is not connected and a motor standstill is detected within 3s, the braking current is switched off after the security time. Therefore a failure is monitored.
