Hi All,
I'm quite familiar with the powerflex 525 and very familiar with VFDs in general, I've got a problem where on a conveyor where a product transfers from one conveyor (one VFD) to another conveyor (another VFD) the drive which is receiving the load will get an overvoltage fault.
I've checked that the speeds are the same, disabled the bus reg and checked for slip but everything seems to be OK.
The fault occurs when both drives are at full speed when the product is transferring from one to the other, which to me would indicate that the previous drive is pushing the downstream drive...but this isn't the case
Does anyone have any ideas?
Thanks,
