I'm fairly certain the braking resistors are burnt out on my 1999 Hurco VMC. I get a spindle load alarm fault anytime the the spindle brakes for a tool change from speeds above 2800 to 3000. If you manually reduce RPM slowly the spindle load increases but does not fault. Anyhow, we've changed resistors on Allen Bradley drives before and it isn't all that difficult, where are they located in the Yaskawa? I was wondering if anyone could give me some advice or photos. I can't tear the machine apart and leave it sit while I explore the drive and order parts. It HAS to run, even crippled. The drive is a Yaskawa Varispeed 626VM3, Model# CIMR-VMW27P5
