Hi
I have been trying to tune my ac drives using the method in the
intergrators manual--Increase the p till oscillate then increase I
till it stops
Oscillation starts at 400 P and I cant get rid of it with a 3000 I
D is zero
The axis will run good with 100 P 5 I 1.2 D with no following errors
at 500ipm Accell is 25 min follow .002 maxfollow .05
There is a slight high pitch buzz in the motors at these settings
The drives are Fanuc, motors are also
There are 3 adjustment pots on the drives themselves could
these adjustments on the drives be keeping me from tuning properly?
I have no documentation on the drives
anyone had any luck tuning Fanuc drives?
Also in an unrelated question-I tried to use G64.1 exact stop mode
and I get an improper code alarm The reason I tried this is
a G0 x5.0 then G0y5.0 will get me a radius in the tool path instead of
a square corner A fast feed move( 120 ipm) of the same locations will
get a smaller radius but still not square.
Thanks
Terry
