Happy "I bought a 3 phase motor and a VFD!" day Playing with the shiny stuff on the kitchen table, and it's all going reasonable well: But I can't figure out whether the YL600/YL620 (this is a 600) can use momentary switches for stop and start. I've been fiddling with P00.16, P00.17 and P00.18 but can't get it to do anything other than run when the buttons are latched. Here's a link to one of many manuals (all slightly contradictory!): YL620-A-Inverter-Manual.pdf (bulkman3d.com) P00.16 reads: 0: FWD(X5)yes,Positive run the command ,REV(X6)yes,reverse run the command 0 1: REV(X6)Determine direction:Open Yes FWD,Shut Yes REV;FWD(X5)Start command:FWD Stop,REV Boot 2:X_EF=EF,X_REV(X5)_DIR=DIR,FWD(X6)= RUN.Three wire control motor operation 3: Stop，FWD(X5) turn off Instantaneous ， positive start motor;run，REV(X6) shut down immediately Stop Stop，REV(X6)Turn off the reverse start motor；run，FWD(X5)Closing action，Stop 4: FWD(X5) turn off Instantaneous ， positive start motor;；REV(X6)Closing 15 action，Stop 5: FWD(X5) turn off Instantaneous ， positive start motor;；REV(X6) shut down immediately Stop 6: Stop，FWD(X5) turn off Instantaneous ， positive start motor;；run，FWD(X5) shut down immediately Stop.run REV(X6)turn off the motor immediately， Reversing 7: REV(X6)When open，FWD(X5)Start-up instant, Positive direction start motor； REV(X6)When closed, the motor is not allowed to start；Runtime REV(X6) Closing action Instantaneous stop P00.17 (input X1) to P00.20 (X4) reads: 0: Retain 1: Multi-segment speed instruction 5: as forward turn point input 6: as reverse point input 7: as point action input / rev x4 to determine direction 8: closing action instant top 9: disconnect action instant stop 11 & 12: speed increase / decrease 12-17: fault indicator inputs Any ideas?
