Switching assembly

摘要

The circuit arrangement (1) has assembly (6) for controlled delivery of clocked power supply voltage for freewheeling operation of holding brake (2). The assembly has free-wheeling diode (14) and suppressor diode (18) connected parallel to an inductor (10) of the brake, where the free-wheeling diode is operated in free-running mode and the suppressor diode is operated in braking operation mode.
