Hi!
Up until an hour ago, I had an Isel ISA 750 spindle. I tried to run this using an Omron JX (3G3JX-AB002-EF) VFD.
I mostly followed the "test run" instructions from the Omron JX inverter handbook:
- Configured the spindle power to 0.75 kW
- Configured the output current to 220V
- Configured number of poles of the motor to 2
In addition, I also configured the frequency settings, but here I was unsure, because the spindle doesn't specify them in the same way as they need to be entered in the VFD. It only lists the "cut-off frequency", which the specs explain as "frequency to which the motor effect is designed". So I thought I would be safe by staying close to those values and made the following settings in the VFD:
- "Base frequency" I set to 295 Hz
- "maximum frequency" I set to 305 Hz
And then I tried to run it. The spindle went up in smoke after approx. 3 seconds, and now has a short between phases.
Now before I try to buy a new spindle and try again, I would like to understand what I did wrong.
Any hints?
