SpletA VFD with a 480VAC input will have a DC bus of approximately 678VDC. Thus the 'pulse' refers to the switching on and off of the transistors producing a pulse of voltage with an amplitude of approximately 678VDC. The goal of the PWM control is to create a sine wave current waveform output to produce torque in the motor. SpletSetting this to a value above zero will change all frequency displays from frequency to RPM. So now the drive is nicely matched to the motor, you can think about matching it to the load and application. Parameters P-01 and P-02 (P1-01 and P1-02 on P2 and Eco) set the maximum and minimum output frequency. Default (Factory) settings are 50Hz (or ... news-herald lake county newspaper
