General description
The type VBMS ... is a compact motor control unit which includes both a motor contactor with a
contact gap
≥
3mm and an electronic braking device.
Because of the integrated motor contactor it is with a modest amount of wiring work possible to
implement the functions „Motor On“ and „Motor Braking“.
The braking current is controlled and can be adjusted within a range of 10-100% of the rated
device current. An integrated standstill detection function switches the braking current off after the
motor has come to a standstill. The control inputs are metallically separated from the load (24V
extral-low voltage).
Various fault conditions are indicated via LED „on“. .
Special features:
•
simple motor control with only a few elements
•
motor contactor and DC-brake in a single device
•
suitable for all asynchronous motors
•
controlled bei microcontroller
•
easy mounting, also for retrofitting into existing plants
•
motor contactor with contact gap
≥
3mm, utilization category AC-3
•
operator’s controls physically separated from load (24V extra-low voltage)
•
connection of several „OFF“-buttons possible (e.g., motor temperature switch)
•
for snap-on mounting on 35mm DIN rail
•
degree of protection IP 20
•
meets trade assoc. requirements for category 2 acc. to EN 954-1 according to the test
principies of GS-HO-01
•
intermateable with BRMS

Usage to the intended purpose
The devices of the VBMS series are electrical equipment that is used in industrial power installa-
tions. They are designed for an application in machines, in order to switch on and to decelerate
drives with three-phase a.c. motors.
Typical applications:
•
sawing machines
•
centrifuges
•
vibrators
