General description
The electronic braking devices of the VersiBrake type enable a non-wearing braking of three-
phase and a.c. asynchronous motors. The braking devices are used for drives that due to safety
and functional reasons have to be reliably slowed down. After the motor has come to a standstill,
an integrated standstill detection switches the braking current off. A potential-free relay contact
indicates if the motor has not come to a standstill within the maximum braking time.
Special features
•
controlled by microcontroller
•
wear-resistant and maintenance-free
•
retrofitting into existing plants possible
•
also available for special voltages
•
for all asynchronous motors
•
integrated braking contactor (devices up to 60A)
•
automatic remanence time optimization
•
overcurrent detection
•
motor PTC monitoring
with option „P“
•
start-delta starting control
with option „D“
•
standstill signaling relay
with option „S“
•
wide-voltage-range-capable
with option „B“
Warning note:
Prior to using the standstill signaling contact for safety-directed purposes, it
is necessary to subject the application to a risk assessment according to
EN 1050 (ISO 14121).

Usage to the intended purpose
The devices of the VersiBrake series are electrical equipment that is used in industrial electrical
power installations. They are designed for the application in machines, in order to slow down
rotating masses on drives with three-phase induction motors.
Typical applications
•
sawing machines
•
centrifuges
•
wood working machines
•
conveying machines
•
textile machinery
