Fig. 3-121: Phase current stage.
The three phase currents are monitored by the P634 to detect when they exceed
the set thresholds. Alternatively, two different thresholds can be active. The
“dynamic” threshold is active for the set hold time of the “dynamic parameters”
(see Section 3.12.8, (p. 3-88)); the “normal” threshold is active when no hold
time is running.
