dead VFD?

[chunkstyle]

Hello all,

Trying to run a file tonight and went to warm up the spindle and found the VFD wasn't powering up.
Turned the bot off and checked inside the control box. Nothing looked different. Closed control box and jiggled the cables. Turned on bot and VFD fired up! Turned it off and on again and no VFD. Machine's hardly ben worked and hasnt been turned on for a couple of weeks. Anyone have a guess on what's going on or what to check? Have a call in to tech support but thought I'd try here in case someone else had a similar situation.

Thanks,
Tim

Tim...
Use a voltmeter and check both sides of the main(rotary) switch AND the contactor that the VFD power runs thru.

Tanx Gary,

Talked to Ryan at SB and we found it. The low voltage wire running to the VFD contactor, inside the control box, was loose. Back up and on the road :)
