Check the network distortion, maybe the capacitance of the capacitors was reduced by aging
processes and with that the resonance point of the system got closer to the dominant harmonic
(fifth by example).
If the problem is in capacitors loosing capacitance, replacing ALL the capacitors should solve the
problem.
After replacing the capacitors
or higher values which indicate resonance symptoms.
-L
Voltage and after Line current, pay attention to what you see when all the groups are
disconnected and when you start to connecting them one by one only one big group at a time
should be connected.
(2)
If you need further assistance take notes of all of those values.
Check if there is signal of capacitor/s blown, if the network distortion is very strong or in rare
occasions when capacitor has an imperfection even one voltage peak could affect the capacitors.
After this event, the total capacitance of the capacitors module is reduced and the resonance
point if closer to the dominant harmonic.

were transmitted. Since each packet that was received correctly to this unit initiates one transmit packet, this
counts the total received ok to this unit. Frame Errors indicate either wrong baud rate or bad link and CRC
Errors are usually indication for bad link.
