The internal structure of the velocity controller is a PID feedback structure, along with anti-windup on the
integrator and low-pass filter on the velocity feedback signal to deal with the sensor noise. It is
recommended to use this controller only as a PI controller (leave the D gain set to 0).
On top of the desired velocity input, the velocity controller also accepts an additional velocity offset and
additionaly, a torque offset can be added to the control loop to improve the control performance. This
dynamically changeable torque value will be added to the torque value generated by the velocity PI
controller.
Although the cascaded position control loop also includes a velocity feedback loop, the velocity controller
described here and especially its controller gains are not used as part of any position controller. This means
the controller gains for the velocity controller described here (objects 0x2011:1 … 0x2011:4) and the velocity
cascade being part of the position controller (objects 0x2012:5 … 0x2012:8) are set independently.
