Follwing error

I have the 5i25 with the 7i77. I have verified the direction and that the encoders work. I have tested the drive amplifiers with a battery to make sure that that system works. I didn't know the encoder scale so we stuck a dial indicator on it and figure it out. Every time that we try to jog an axis it gives an immediate follower error. We don't I or D to anyting and we have tried different values of Pgain 1,10,100,1000 with the same error. Not sure what we are doing wrong or need to do.

Thanks,

I would first make sure the you can enable and disable the drives under linuxcnc control,
then increase the FERROR and MIN_FERROR to about 1 inch so you can see the
servo motor behavior without immediately faulting.

With the default (small) values of FERROR and MIN_FERROR, immediate faulting is expected
on a untuned system.

You may also find that you feedback is backwards so you will get an immediate run-away,
or the drives are not enabled so dont move, or you have large oscillations because the tuning is not right.

In any case you need to widen the following error limits(FERROR and MIN_FERROR) so that you can see whats going on.

How you tune depends on the drive type (velocity or torque)
