摘要: A method for dynamically braking a motor, the motor having plurality of terminals and receiving an input alternating current voltage waveform, by detecting zero crossing waveform position waveform: sampling appearing at terminal to develop sampled value position, comparing reference setting flag if matches introducing delay period generating gating pulse fire silicon controlled rectifier provide then halting flags each positions are set. Also electronic dynamic brake assembly operable in SLAVE mode, PRE-STOP HOLDING mode MASTER mode.
