Hello all,

I've got a 6040 PRT-E1500w from ebay.

My VFD is non responsive. It is stuck displaying an error code which I cant seem to move past. All VFD buttons are unresponsive. I don't know what the error code means. The error code reads: "E CH".

I can still control the machine through Mach3. I can jog every axis, and I can run some gcode...everything goes except the spindle, and the control box showing "E CH" incessantly. When I try to start the spindle throuch Mach3 the VFD emits a faint but clearly audible kind of electronic clicking sound. A single click when I try to turn the spindle on, and another click when I try to turn the spindle off (through Mach3).

I'm a bit worried. Is something fried? Yikes! I'm very worried.

Any help would be much appreciated.

Thanks
