We have six Allen Bradley PowerFlex 1336 PLUS II VFDs/Inverters installed at our plant connected through ControlNet using 1203-CN1 Scanport. The problem is that sometimes the fault light on the Scanport module starts blinking of fault and the HIM on the VFD display F 10 which is serial fault. The problem occurs randomly and has happened on all the six drives. The frequency of occurrence is also random. It came recently after a couple of months.
What could be the possible reasons for this? I’ve gone through the manual and none of the Actions the manual says are really applicable to my case.
Thanks
