Thank you for help. I will reroute IO modules "FG" wires tomorrow and test. I also use left side channel for most VFD power wires but there is couple of drives supplied from the right side channel. Signal and control wires are in the right channel but there is also in the left. I mixed them because of space which probably make problem with noise coupling. I will try to separate them as much as possible and see if this fix the problem. Regarding ferrite beads (rings), maybe this can help but I can not get them soon. I could also try to install metal plate between drives and upper part with IO modules as proposed by @Gabriel Franco just I am not sure how to install it? At the end, I could change switching frequency of the drives. Now is 8 KHz if I remember correctly. I can put it to 6 or 4 KHz if this could help? Tommorow I will test this things and see what happens. Thank you again for help. -
Could you please put up screenshots of your ComInits, for both 1 & 2. And in doing this, you might find a teensy weeny little thing that is the issue! That's what I find when I'm finally asking about a frustrating question...the typo suddenly stares me in the face, saying "Here I am...I've been waving at you all day!" I am suspecting that perhaps your timeouts on 1 are shorter than on 2. What do the status bits on using both ports say when trying things? As well, you say yet you are doing 485 on the plc, which at the speed you have is not a fast process and allowances have to be made accordingly. But also please explain the "232" setup. cheers, Aus -
I am trying to change your setup... I had a similar design with 9 frequency converters (unfortunately, there is no photo). V1210 is used with expansion modules on the backplaine. There were no problems. But all grounding is done in one bus at the bottom. I placed the power wires to the left, and the signal wires to the right of the frequency converters.
