Hi, I am trying to make the ABN3 run (testing) with DC motor, encoder, switches for OD, CD, NDG and the cams on motor shaft for DOL and DCL. I was able to make it run using MDC and MDO on board, but no with the OD CD NDG switches, I can measure OD/CD/NDG switches okay on Q2~Q4. It seems it is in inspection that blocks OD CD NDG. What I am missing? I got LEds lit DOL/DCL when the motor shaft cams switches reach DOL/DCL, but the corresponding relays K1~k4 did not click. Tested 3 boards already, same issue. Setting manual speed for open/close to 260 I was able to make the motor run nicely with MDC/MDO. Using setup for Harmonic DC motor. Using 6300HL1 LCD+4 switches for setup. This board has no RS485/CAN communication (as far as I can see). Can anyone help me ? Thanks.
