If the “fms” value depends on spindle speeds, specify the gradient.
Example:
If “fms” is 90000 for an “S” value of 5000 and 140000 for S10000:
Gradient = b/a
a
b
S100005000
90000
140000
fms
Since “cms” = (140000 – 90000) / (10000 – 5000) = 10, set “10” in the
above example.
Note:
Set the spindle viscous friction coefficient “cms” when SA45 bit 0 = 1.
(Enter, moreover, 1000 times the respective calculation results in this
case.)
