nelukow Posted May 16 Share Posted May 16 I currently have a 48V brushless motor connected and I'm supplying 1-phase 220V. The amplifier accepts inputs of 240V 3-phase, 110-240 1-phase, or 48V DC. When I select the amplifier, it requests the input voltage in "VDC". #1: Do I actually have to calculate VDC from VAC? The manuals were unclear about this. I used VDC= VAC*.636 = 220*.636 =139.92VDC or ~140V as seen below. #2: Is my understanding of this amplifier correct...am I outputting 48V DC to my motor as long as I set PwmSf correctly? Motor1.PwmSf = 0.95 * 16384 * 48V / 140V = 5336.5 Quote Link to comment Share on other sites More sharing options...
