Parameter 171
There are four possible values for parameter 171 which select which hand wheel and touch probe system is connected:
0 = HR150 or HR250 and TS510
1 = HE310 and TS510
2 = HR150 or HR250 and TS110
3 = HE310 and TS110
TS110 is a cable connected touch probe
TS510 is optically connected to a remote unit that then is cable connected
So you need to decide which handwheel you have and select for it. I think the fact that the touch probe is not connected is irrelevent to this parameter
