I have a 1994 Fadal 4020HT with the 88HS control.

As far as I can tell this machine left the factory with rigid tapping installed or it was installed later. It has the right puzzle pieces, wiring is there, encoder is there, rigid tapping spindle drive. The only missing piece is that there was a 1010-1 card installed which doesn't support rigid tapping.

I purchased and installed a 1010-4 spindle control card with the rigid tapping e-proms installed, plugged in the encoder feedback cable but upon trying to start the spindle I get a error #10 spindle overload message. I have checked the jumpers are correct on the 1010-4 card and the red light is flashing when the machine is turned on.

Spindle drive is a yaskawa cimr-f7u2011

Any ideas?

Thanks
