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

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.

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“.

„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%.

12 VBMS ....
12.3 Parameter settings
Sequence of steps during commissioning:
(the designations/details indicated in brackets refer to the circuit-board version)
1. Disconnect the plant/system from the supply mains.
2. Adjust the requested braking current with the potentiometer „I“, „(P2)“.
Since the potentiometer reacts roughly linear, it is possible to infer the braking current from
the potentiometer setting.
Left stop (counter-clockwise direction) roughly equals 10% of the rated device current
(20A).
Mid-position roughly equals 50% of the rated device current.
Right stop (clockwise direction) equals 100% of the rated device current.
3. Adjust potentiometer „n0“, „(P1)“ to approx. 40%.
4. Switch on the plant.
5. Initiate braking by switching the motor ON/OFF.
Note: When putting the device into operation for the first time, the braking current
can be checked with a true r.m.s. measuring instrument.
Adjusting the braking current
The braking current is to be adjusted to a value as small as possible, in order to avoid
unnecessary heating of the power semiconductors and motor. This is especially important in the
case of high switching frequencies. We recommend to limit the max. braking current to 2.5 times
the rated motor current.
The requested braking torque can be adjusted with the potentiometer „I“, „(P2)".
Adjusting the braking time
No adjustments are required, since the braking current is automatically switched off approx. 1.5s
after a motor standstill has been detected.
If no standstill is detected during the max. braking time (10s in the case of standard devices), the
braking current is switched off when this time is over. This case is indicated by the LED „ready“,
„(V9)“ (flashing 1x).
Adjusting the standstill threshold
In most applications, the factory-setting (40%) produces good results.
If the braking current is switched off before the motor has come to a rest, or if the braking current
is not switched off approx. 1.5s after the motor has come to a rest, it is possible to make an
adjustment with this potentiometer. The optimum setting has to be found by carrying out several
braking operations. The potentiometer should be changed only in little steps (10%). For a more
detailed functional description please refer to page 9.

13. Dimensioning rules
Note! All data sheets and commissioning instructions are avaialble on our
homepage at www.peter-electronic.com.
13.1 Dimensioning of braking device
For most applications, it is relatively easy to select a suitable braking device.
In most cases, an acceptable braking torque is achieved, if. during braking, the motor is
connected in Y (star) and the braking current is 2 times as high as the rated motor current. If,
during braking, the motor winding can only be connected in Δ (delta), the braking current has to
be at least 2.5 times as high as the rated motor current in order to achieve a sufficiently high
braking torque.
If special applications require more precise calculations, the following formula can be used.
Calculating the braking current (IB))
Table 1
IB = Braking current in A
fB = Braking factor acc. to table 1
tB = Braking time required (in s)
IN = Nominal/rated motor current (in A)
tA = Time until nominal speed is reached
(in the case of motors with star-delta start - approx.
switch-over time)
Values usual for tA:

VBMS .... 15
Calculating the cyclic duration factor (ED):
If the required cyclic duration factor (c.d.f.) exceeds the permissible values indicated on the data
sheet, the permissible maximum braking current is to be accordingly reduced. The data required
in this connection can be found in the device-specific commissioning instructions.
If it is not possible to reduce the braking current, a braking device with a higher braking current
has to be used.
Example: If the required c.d.f. is twice as high as the value indicated on the data sheet, a
braking device of twice the nominal/rated device durrent has to be used.
13.2 Dimensioning of pre-fuses
Basically, two types of fuse protection are available for the user:
1. Fusing according to allocation type „1“, DIN EN 60947-4-2.
After a short circuit, the braking device is allowed to be inoperative.
2. Fusing according to allocation type „2“, DIN EN 60947-4-2.
After a short circuit, the braking device must be suitable for further use. However, there is
the danger that the contacts of the braking relay (braking contactor) weld. Therefore, if
possible, these contacts are to be checked prior to applying again mains voltage to the
device. If this check cannot be carried out by the user, the device has to be returned to the
producer in order to have it checked.
The following dimensioning information refers to the below operating conditions:
• Use of standard asynchronous motors
• Braking time not exceeding 20s, for braking devices up to 36A
• Braking time not exceeding 40s, for braking devices from 40A up
• Braking current not exceeding 2.5x INOM of the motor.
• Cyclic duration factor (c.d.f.) not exceeding the value indicated in the data sheet.

16 VBMS ....
Fusing according to allocation type „1“:
As pre-fuses, we recommend to use line protection fuses (utilization category gL) or automatic
circuit breakers with tripping characteristic B, C, D or K.
Taking into account the maximum braking currents that occur (normally the rated device current),
we recommend fuses according to table 2, column 3.
Note: Wiring cross-sectional area according to DIN VDE 0100-430,
DIN EN 57100-430.
Fusing according to allocation type „2“:
The power semiconductors are to be protected by fuses of the utilization category gR (semicon-
ductor fuses, high-speed fuses). However, since these fuses do not ensure line protection, it is
necessary to use additionally line protection fuses (utilization category gL).
As for the dimensioning of the line protection fuse (gL), please refer to table 2, column 3.
To protect the semiconductors it is necessary to select gR-fuses featuring cutoff-I²t-values of the
ranges indicated in table 2, column 4. In this connection, the fuse rating of the selected fuse
should not be smaller than the braking current to be expected (rated device current).
Note 1: On the basis of the recommended I²t-value, braking current, and possibly the
c.d.f., the fuse supplier is able to select a suitable type. Due to the great
variety of producers, sizes, and types, PETER electronic does not
recommend any particular fuses.
Note 2: If the fuse or cutoff-I²t-value is selected too small, it may happen that the
semiconductor fuse reacts during braking.

13.3 Permissible braking frequency
The braking frequency depends on the adjusted braking current:
Warning:
When setting up a machine or during commissioning, it is possible to carry
out 5 braking operations in succession, i.e., with rated device current and at
a braking time of 10s. After such operating conditions, however, the device
needs a recovery time of 15 minutes.
