For quite a while I've been having a challenge with the variable frequency drives I use to run vibrating motors on some equipment here. The challenge is the drives keep failing every time. I've used different brands of Inverters (Toshiba, ABB and Omron) so I believe the problem does not have to do with the brand of inverters but probably there's something I may be missing.
For the Toshiba and ABB inverters I lost all the IGBTs, but with the Omron (Part ID : 3G3MX2-A4015-E)which I'm currently using trips off with an error code E30 (Drive Error). This error does not permit me to reset even after I cycle power without the load connected.
The motors are new and their insulation resistances are good. Insulation resistance of the cables are also good.
I have 4 A Circuit breaker between the main 3-phase supply and the inverter and and output reactor (rated for this specific Omron vfd) between the vibrating motor due to the length of my cable (about 60 meters) to reduce the harmonics on the output lines. Each motor is connected to an Inverter.
Please I'm open to all Ideas. Kindly help.
