1.8.6 Speed Zero Control Block (Spd 0 Logic)
The Function of the Speed 0 Block is active only in a Sensorless and Field oriented mode.
The Function generates the Speed 0 signal, Spd is zero, and the Reference 0 signal, Ref is zero.
In the
configurations it is possible to set: with Spd 0 speed thr and Spd 0 spd delay the Speed 0 threshold and
delay; with Spd 0 ref thr and Spd 0 ref delay the threshold and the delay of the reference 0. Furthermore
with Spd 0 enable it is possible to enable the gain adaptive function with a
Speed 0 value and with Spd 0 P gain
and Spd 0 I gain to adapt the Proportional and Integral gain to a Speed 0 value.
The gains become active when both conditions Spd is zero and Ref is zero are true. They are not active when
Ref is zero is false.
