I work for an oem manufacturer. We make hundreds of units per year. These machines go in schools and damp environments. The customers need the machines to run on 110v. Yes I am referring to dynamic braking resistor outputs. My company buys hundreds of vfds per year so I get them cheap. I have...
Rhatcher,
I have tried turning the carrier frequency down with no luck, but it did reduce the leakage current.
Mikekilroy,
I spoke with an engineer at marathon, he told me to connect it with the negative side of the DC brake output and that's the only thing that will work
Itsmoked,
I have...
Mikekilroy,
I have attached documentation from marathon explaining what they have done. Thank your for the suggestions, I will play with them a bit.http://files.engineering.com/getfile.aspx?folder=031d97ae-2396-4750-9230-1366234ba337&file=LCS_QMI_9-28-2009.doc
I am trying to run a 1hp, 3p motor with a vfd. I need the motor to run on a gfi. I have tried several different brand of motors as well as drives. Every configuration has caused the gfi to trip. With some testing we determined the trip was caused by current leakage from the motor. I contacted...
