Bridgeport interackt 412 -1987 Spindle running problem..

[Henrik]

Hey there..
I have this bridgeport and the backup batteries has run out of power,then i replaced them and reentered all the machine parameters,then i get it almoust running it cut get the x,y,z in reference.
But then ill try to get the spindle runnung so i go in manual mode and press the tool call button and entered spindle rpm at 200 and enter, but it just says that the spindle rpm is `invalid`??
What are im doing vrong...
The bp is from 1987 and has being standing whit no power on for about 2 years,i gat it for almoust nothing and now its standing in my new shop and it cut be fun to get it running again.
Regards
