The bridge-half-wave rectifiers are used to supply electromagnetic DC spring-applied brakes which are ap-
proved for use with such rectifiers. Other use is only permitted with the approval of INTORQ.
Once a set overexcitation period has elapsed, the bridge-half-wave rectifiers switch over from bridge recti-
fication to half-wave rectification.
Terminals 3 and 4 are in the DC circuit of the brake. The induction voltage peak for DC switching (refer to
the circuit diagram DC switching at the motor – fast engagement) is limited by an integrated overvoltage
protection at terminals 5 and 6.
