Control of a <strong>motor</strong> with<br />
an electromechanical<br />
brake<br />
An electromechanical brake with infeed from the main voltage (L1/L2/L3)<br />
should not be connected directly to the output of the <strong>soft</strong> <strong>starter</strong>. An electromechanical<br />
brake should be <strong>control</strong>led by means of a separate contactor (K1<br />
in the circuit diagram below):<br />
