These are the settings I changed from factory after initial reset on the YL620-A 110V VFD to run a 1.5kw spindle using the BlackBox 0-10v to control spindle speed via openbuilds control software. factory reset P00.13 = 10 Cycle power and change the following settings: P00.00 = 400 ; Main Frequency P00.01 = 1 ; Start Stop Source: 1=External P00.03 = 1 ; Stop Mode: 1=Coasting Stop P00.04 = 400 ; VFD Highest output frequency P00.05 = 400 ; VFD Maximum Voltage Output Frequency P00.06 = 110 ; VFD Highest output Voltage P00.07 = 140; VFD Middle Frequency P00.08 = 35 ; VFD:Middle Voltage P00.09 = 120 ; VFD Minimum Frequency P00.10 = 30 ; VFD Minimum Voltage P00.11 = 110 ; not sure P00.16 = 1 ; 1= REV(X6) Determine direction:Open Yes FWD,Shut Yes REV;FWD(X5)Start command:FWD Stop,REV Boot P01.04 = 110 ; Overcurrent Setup P01.16 = 100 ; Direct start Initial frequency(Improve start Torque) P02.00 = 105; When speed up torque will increased P02.01 = 100; Deceleration time - Torque Boost P03.08 = 120; Panel potentiometer, frequency given of lower limit P03.09 = 400; Panel potentiometer, frequency given of Upper limit P03.12 = 30 ; Analog lnput 1 frequency given lower limit P03.13 = 400 Analog lnput 1 frequency given upper limit; P04.11 = 1 ; Stopping Mode: 1=Coasting stop P06.00 = 0 ; Acceleration Time P06.01 = 8 ; Accel.Time 1 P06.02 = 8 ; Decel. Time 1 P07.00 = 400 ; Frequency 1 P07.08 = 3 ; Frequency source selection 1 (3=Analog Input.：P03.10~P03.13) P11.01 = 2 ; Output Voltage (V) P11.02 = 7 ; Output Current (A) P11.03 = 400 ; Output Frequency (Hz) P12.00 = 7 ; Rated Motor Current P12.01 = 110 ; Rated Motor Voltage P12.03 = 5 ; Motor no-load current P12.05 = 14 ; Converter rated current(A) P12.06 = 110 ; Converter rated Voltage(V) I’ve been running these settings for 6 months with no issues. Spindle only runs about 10 degrees warmer than ambient, even after running for hours. The following is a link to settings for 2.2kw 220v vfd, however, I have not verified these settings. Test at own risk. Vfd YL620-a initial setup they do discuss one setting that I can’t find any info on. It’s P11.01. I have mine set to 2 since I think it’s motor horsepower (1.5kw = 2hp).
