Uncoordinated Axis was created by RLA
Hi...need help..on 5 axis setup...A Axis now is not coordinated..also gives false warnings about going beyond a limits in file at line 72...
I have used this machine before in a similar way but not rotating more that 90 degrees either way...seems like it keeps looking to end of file and then starts moving continuous ahead of other axis??

Thanks for any help!!

Rick

Not sure about the other errors but P should be 1000
(for all joints at a 1 ms servo thread rate) A P value
of 0 will work for a while but the joint will drift because
there is no position feedback.

[JOINT_3]
TYPE = ANGULAR
HOME = 0.0
FERROR = .5
MIN_FERROR = 0.05
MAX_VELOCITY = 40.0
MAX_ACCELERATION = 12.0
# The values below should be 25% larger than MAX_VELOCITY and MAX_ACCELERATION
# If using BACKLASH compensation STEPGEN_MAXACCEL should be 100% larger.
STEPGEN_MAXVEL = 100
STEPGEN_MAXACCEL = 50
P = 0
I = 0
D = 0
FF0 = 0
FF1 = 1
FF2 = 0
BIAS = 0
