Issue(s):
- VFD reads 125
- Spindle cannot go higher than 7500 RPM
Resolution:
This is caused by a bug when first enabling RS485 control. Turn OFF and ON the controller using the slide switch, then unplug and replug the VFD power cord.
If it 7500 is still appearing, press SHIFT on the VFD you should have an option to set the display to Hertz (Hz). Then the 7500 should disappear.
I would also recommend doing this spindle reset process, since there is a tendency for the board to revert back to the default spindle output instead of the previous chosen option.
