11.2 Connection
The braking device is to be installed according to the attached connection diagram. For other
connections please consult PETER electronic GmbH & Co. KG.
Note: Further connection proposals for special circuit arrangements are available
via our homepage at
www.peter-electronic.com .
Note: Prior to putting the motor brake into operation the wiring is to be checked.
To ensure reliable function is it necessary to comply with the interlocking conditions:
The interlocking contact of the braking device, terminal X5 (X5), X6 (X6), has to be looped into the
control circuit of the motor contactor, in order to
prevent the motor contactor from pulling in during
braking.
11.3 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.
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)".
The braking current can be measured with a clamp-on ammeter (True RMS) or a corresponding
moving iron amperemeter at the output terminal "4T2" of the braking device
