Page 70 SY8600 High Performance Vector Control Inverter User Manual Fig. 6-8 Jump frequency and its range p2.28 FWD/REV dead time Setting range: 0.1～3600s FWD/REV dead time: the waiting and holding time before the motor changes its rotating direction after the inverter's output frequency is decreased to zero. It is the time taken by the motor to change its rotating direction when the inverter receives REV command during its running process.
Page 71 This function is mainly used to improve system performance, and reduce noise and vibration. Since SY8600 series adopts IGBT as power devices, carrier frequency can be higher. Increasing carrier frequency can bring following benefits: better current waveform, lower noise, which is especially suitable for applications that need low noise.
