Hi all,

I am trying to use a haas servo controller and haas indexer (HA5C) to make a semi-fourth axis on a mini-mill. I plugged the servo controller into the mill via straight through RS232 cable. Tried changing setting 38 (Aux axis number) on the mill to 1 and it gave an error saying that there was no aux axis connected. I know I can wire the servo controller via the relay and use M-codes to index, but I would like to be able to program it more in depth through the code. I am not sure what to do....
