<1> For p1462 = 0.0, the I component is disabled (integral time
<2> For torque control, the I component is set to the value of r1515 (total supplementary torque).
<3> This parameter is set to 0 when pulses are canceled.
<4> The integrator of the speed controller is re-parameterized to become a PT1 filter through a feedback element (p1494).
