<1> This controller increases (boosts) the DC link voltage when the modulation depth limit has been reached (p3480).
<2> When the pulses are enabled, the DC link voltage is ramped (p3566) from the actual value to the setpoint p3510.
<3> Applies only if the "Master/slave" function module is activated (r0108.19 = 1).
<4> Applies only if the "Additional Control" function module is activated (r0108.3 = 1).
