1. Safety notes
The described devices are electrical equipment for use in industrial electrical power
installations. An impermissible removal of the covers during operation can cause
serious damage to your health, since these devices contain live parts with high
voltages.
Adjustment work may only be performed by trained staff observing the safety regulations.
Assembly and mounting work may only be carried out with the equipment deenergized.
Make sure that all drive components are properly earthed.
Please read these commissioning instructions carefully before putting the device into operation.
Besides, the user must ensure that the devices and associated components are fitted and
connected in accordance with the appliable local, legal and technical regulations. The VDE-
regulations VDE 0100, VDE 0110 (EN 60664), VDE 0160 (EN 50178) , VDE 0113 (EN 60204,
EN 61310),VDE 0660 (EN 50274) plus the appropriate regulations of the TÜV (Technical Control
Association) and the trade associations apply in Germany.
The user must ensure that the drive turns into a safe operating state following a device failure, in
the event of maloperation, or if the control unit has failed etc..
Caution: Even if the motor is at rest, it is not physically separated from the mains.
2. Conformity
In industrial linguistic usage the electronic brakes with motor contactor of the type series VBMS...
are called "devices", however, in the sense of the "device-safety-law", the "EMC-law" or the "EC
machinery directive" they are not devices or machines ready for use or connection but they are
components. It is only possible to define their final function, when these components are
integrated into the design and construction of the user.
To be able to use the devices to their intended purpose, it requires power supply networks
according to DIN EN 50160 (IEC38).
The user takes the responsibility that the user’s design and construction comply with the appli-
cable legal provision.
The commissioning is strictly forbidden as long as the conformity of the final product with the
guidelines 2006/42/EC (Machinery directive) and 2006/95/EC (Low voltage directive) is not
proved.

3. 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
4. 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

7. Functional description
The terminals for the „ON“ or „OFF“-buttons are connected to a 24V extra-low voltage that is
physically separated from the mains potential.
When actuating the „ON“-button connected with the terminals X1-X2, the integrated motor
contactor switches the motor on.
If one of the contacts on the terminals X3-X4, X5-X6 or X7-X8 is opened, the integrated motor
contactor switches off and initiates braking. During braking, the integrated motor contactor is
interlocked against switching-on. After a delay time which, dependent on the amount of the
remanent voltage of the motor, optimizes itself, the integrated braking relay pulls in. After the
contact bounce time has been waited out, a controlled d.c. current is fed into the motor winding.
The magnetic field resulting from this has a braking effect on the still rotating rotor. The d.c.
current is generated by a thyristor phase control. Special suppressor circuits protect the power
semiconductors against overvoltage.
With the potentiometer I, the braking current (and thus the braking torque) can be adjusted within
a range of 10 … 100% of the rated device current. The integrated motor standstill detection,
which functions via the amount of the remanent voltage, switches the braking current off approx.
1,5s after a motor standstill has been detected. To be able to adapt the device to a variety of
motors, it is possible to adjust the standstill threshold via the potentiometer n0).
Faults that occur during operation of the device are indicated via the „ON“ LED.
A motor protecting switch may additionally be wired in series before VBMS... device.
For this purpose, the wire jumper between 5L3 and 5L3’ has to be removed. The wiring is then to
be effected as illustrated in the connection diagram.
Warning notices:
To ensure a reliable standstill detection function, it is necessary to comply
with the following:The braking current must not exceed (3) three times the
amount of the rated motor current. If the VB-L is operated without the 6T3
(T3)-terminal beeing connected, which always applies in the case of single-
phase applications, it is to be ensured that braking current flows at least for a
period of 1.5 s before the motor comes to a standstill, as no motor standstill
is detected within this period of 1.5s and the braking current would then flow
over the total maximum braking time. This could cause destruction of the
motor and fault indications of the braking device.
Note: If the braking time at rated device current is too short, due to the fact that the
centrifugal masses to be slowed down are too large, either a device with a
longer braking time can be inquired of the producer or a device featuring a
higher rated current has to be used.

9. Control inputs
Warning
Please note, the total contact resistance on terminals X3 - X8 of the
connected contacts must not exceed 50 Ohm. If the limit of the total contact
resistance is exceeded, a reliable operation of the motor relays at 90% of the
mains supply (230V or 400V depending on device model) is no longer
ensured. In this case the motor could start on 2 phases.
10. Potentiometers
With the potentiometers it is possible to adjust the following parameters.
Note! If the potentiometer is adjusted to a position too far in clockwise or counter-
clockwise direction (e.g., end stop position), it may happen that no standstills
are detected. In this case, braking current flows until the end of the max.
braking time. The LED indicates „no standstill during the max. braking time“.

Braking contact Connection of an „OFF“-button (normally closed
contact)
„I“ Adjusting the braking current:
The braking current can be adjusted in the range from approx. 10% - 100% of the rated
device current. The adjustment is roughly linear.
„t“ Adapting the standstill threshold and braking behavior at motor standstill.
With this potentiometer it is possible to adapt the motor standstill threshold to various
motor types and applications and to influence the behavior of the braking current at
motor standstill.
In „left stop“ (full counter-clockwise) position, the standstill detection function is most
sensitive, and the braking behavior, upon reaching the motor standstill, is most soft.
Possibly, the braking current is switched off even before the motor has come to a
standstill. The potentiometer has to be adjusted so that the braking current is switched
off approx. 1-1.5s after the motor has come to a standstill.
Factory-setting: approx. 40%.
