I am not sure that they are mentioned in the docs, but they exist in the code:

github.com/LinuxCNC/linuxcnc/blob/2.7/sr...tmot2/encoder.c#L509

So you need to set the "error-enable" bit in the HAL, and then you can monitor the outputs.

In case someone has similar problem wanted to report back.

After changing out the cables, CNC has not had any issues. So must have been encoder cables that I replaced. Used CNC a lot since then and been acting perfect [knock on wood].

Thanks for everyone's help as always.

I have a Precix to retrofit for a customer. Did you end up swapping out motors and/or drives? Or did everything work ok with the 7i77?

Bevins,

No, I kept using the same motors. Same motors/drivers/power supply.

I'd be glad to help however I can, if you have any specific questions ask away! Otherwise I will record a quick video of how my machine is set up, maybe can help or anyone else with a retrofit.

Used it today worked fine.

If you do use same motors, maybe we can compare notes on servo tuning :) Which model are you retrofitting?

It is a 2100 Series CNC Router DC3BR. 3 phase motor drives and 3 phase spindle inverter. thats all I know for now. The customer hasn't got back to me with more details. Its a Oct 2000 manufacture date. Delta VFD, Perske servo's.

thats all I got now. It kinda looks like your control box.
