Quadrant 1 operation is defined as motoring in the forward direction, speed and torque both having positive values.
Operation in quadrant 2 is defined as regenerating in the reverse direction, where speed will be negative and torque positive.
Quadrant 3 operation is defined as motoring in the reverse direction, speed and torque both having negative values.
Operation in quadrant 4 is defined as regenerating in the forward direction, where speed will be positive and torque negative.
When adaptive control is enabled, which is the default status, the current loop employs two different algorithms, one of which applies high gain in the
discontinuous current region. This is unsuitable for some applications, such as non-motor loads, for which adaptive control should be disabled.
When set, enables the continuous auto tune which continuously monitors the motor ripple and adjusts Motor constant (Pr 5.15), Continuous
proportional gain (Pr 4.13) and Discontinuous integral gain (Pr 4.34) for optimum performance. The commissioning / start-up autotune should still be
carried out because Continuous integral gain (Pr 4.14) is not set by the continuous autotune.
Calculation of the gains is suspended when the voltage field weakening voltage loop becomes active so that the gains are not increased when the
field is weakened.
