Hi. I'm installing a PRSStandard 96-48. But I'm used to operate a PRSAlpha.

The machine has a 4hp 3phase HSD spindle.

Every thing is wired correctly. The vfd is working correctly and I can change the RPM from the control software.

But I can't get the spindle to turn

My question is:
In a PRSStandrd, do I have to connect the two wire brown cable to somewhere in the control box?
In the alpha I use alt-1 alt-4 and push Start. In the standard I don't have the button box, so how do I start the spindle?

Thank you
