PWM Voltage Wrong After Random Disconnect – No Company Support

Hi Josiah, did you write down your VFD parameters before the reset? Please refer to VFD Parameters (Huanyang model) it has a good discussion on setting up the inverter. I think between PD010 and PD011 you can set a minimum operating speed higher than the “command” generated by the PWM offset from the controller. this would prevent operation at that low a speed but get the spindle to stop with just the offset voltage.
