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.
