BR 230/400-10...400 Functional description (see connection diagram) After switching on the operating voltage on L1 and L2 the main contactor interlock (terminal X5,X6) closes. The motor can be started. A starting logic makes sure that braking is not yet initiated when the plant is switched on with the master switch while the motor is still switched off. -

BR 230/400-10...400 Potentiometers With the potentiometers on the front panel of the BR-devices the following paramteters can be adjusted. „I“ Adjusting the braking current Adjust the braking current as small as possible, in order to avoid unnecessary heating ot the power semiconductors and the motor. This is especially important in the case of frequent operation. -

Page 14: Dimensioning Rules
BR 230/400-10...400 Adjusting the braking time The time, in which the braking current flows, is to be adjusted with the potentiometer "t". It should be so long that, as soon as the motor has come to rest, the braking current is switched off. When the motor has reached operating temperature, check the settings and, if necessary, readjust them. - Page 15 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.
