Brand new machine and having trouble getting the VFD activated. Not having any Errors showing, but when initiating the warm up nothing happens. I have selected to Redline VFD in the spindle configuration. Any ideas?

What is on the VFD display when you start the warmup? Flashing zeros?

Ensure your vfd is in automatics mode not manual mode (covered in manual)
