The Position Loop Bandwidth attribute determines the proportional gain, Kpp, of
the position loop that multiplies the Position Error signal. This value represents
the unity gain bandwidth of the position loop beyond which the position loop is
ineffective.

The Position Integrator Bandwidth attribute determines the position loop
integral gain, Kpi, which together with the Kpp, multiplies the integrated Position
Error signal. This value represents the bandwidth of the position integrator
beyond which the integrator is ineffective. A value of 0 for this attribute disables
the integrator.

Position Units
The Position Lock Tolerance attribute establishes a window around the current
command position. When the actual position is within this window the Position
Lock status bit is set. When actual position falls outside this window, the Position
Lock status bit is cleared.

The Position Error Tolerance attribute determines the absolute maximum
Position Error value that can be tolerated without causing an Excessive Position
Error exception.
