bradodarb,
your post does not state if you have static or dynamic converter. is your converter adequate for the motor load? some eu motors are a little fussier than american motors are, as to the quality of power going to them. make sure that the motor is wired for low voltage. any accessories such as power feeds or lubricators should not be connected to the manufactured leg. there should be fuses as well as contactor with correct heaters in line with the motor switch. be sure that the contactor coil is supplied with the correct voltage. (this goes back to not using the manufactured leg to operate the contactor coil). be sure all connections are tight. be sure the wire is sized to handle the loads from the mill. try to get a copy of uglys electrical referances (isbn 0-9623229-2-x). this book answers most of my 3 phase questions. i am not a licenced electritian, nor do i play one on tv. please check with a local electrician familiar with 3 phase wiring.
any other members, please correct my advise to this member, if i am leading him the wrong way.
let me know how things work out for you.

i hope this helps you  |
