Knows someone this error message

Hello,
i am retrofitting wood cnc machine with 5I25 and 7I77. I have connect the 3 encoder and when i move the axes withhand the dros are working. I test the servosystem with an analog signalgenerator, the axes are moving with a + - 10V signal, then i connect the amplifier inputs with the analog output from the 7i77 the axes move very very slow, normally i think they had to stand still. When i activate the manual working button on axis after two seconds the button is deaktivated and there is a error message: "joint 2 following error". Does someone knows what this mean?

Thanks

Hans

Have you tried tuning the PID loop in Linuxcnc?

Hello,
in what kind of way can i test the analog outputs. When the analog outputs are not to the servos connected and the servos enable there is no drift and i cannot move the axes with hand.
Means "Joint 2" that this means axes 2?

Thanks

Hans

You should expect a slow drift (or even a fast runaway, so be careful ) and following errors
when first enabling the servo loop and before things are tuned. Here is JTs velocity mode tuning guide:

If you are using Axis, the ""Machine --> Calibration" menu item can be use for tuning the PID values
