2-2. Macro variable for measuring cycles
The following variables are necessary to control the movement of a probe. Please be sure
to set these variables before using measuring cycles.
Note) If the following data is empty or zero, the alarm is occurred.
#210
: Feed-rate for the first measurement (f)
#211
: Approach distance for the first measurement (
α
)
#212
: Escaping distance for the first measurement (
β
)
= Approach distance for the second measurement
#213
: Overlap distance for measurement (
γ
)
The offset amounts between stylus ball center and spindle center
#214
: Feed-rate for approaching start point (fa)
If the probe collide with work-piece (fa), the alarm will occur and stop
immediately.
#215
: Escaping distance for the second measurement (

)
