Based on the pole-zero cancellation technique, the controller gains are evaluated by:

Where A and B are the internal digital controller scaling (A*B = .006016) and T is the controller
sampling time introduced for sampling compensation.
The following gain calculation illustrates a drive application setup with Parameter configurator

The current controller in the Sensorless FOC block module directly uses these gains.
MCE designer provides current loop diagnostic test function. This test provides the response of
the current control loop and also the steady state accuracy.
