The Velocity Integrator Control attribute controls the behavior of the velocity
loop integrator while commanding motion through the controller. When the
integrator hold enable bit is set, the integrator is held while motion is being
commanded with a non-zero velocity. When clear, the integrator runs without
qualification. When the auto-preset bit is set, the integrator preload value is
automatically loaded with the current torque command when there is a control
mode change between torque control and velocity control. If clear, the integrator
is loaded with the configured velocity integrator preload value.

The Velocity Integrator Preload attribute is a value assigned to the velocity
integrator when the velocity control loop is enabled.

The Velocity Low Pass Filter Bandwidth attribute controls the bandwidth of the
Low Pass Filter applied to the Velocity Error signal. Recommended
implementation is a two pole IIR filter. A value of 0 for this attribute disables this
feature.
