The TRIP1 tripping command and signal are generated after N1 slips in zone 1,
providing the rotor angle is less than
TripAngle
. The TRIP2 signal is generated after
N2 slips in zone 2, providing the rotor angle is less than
TripAngle
.
All signals are reset if:
•
the direction of movement reverses
•
the rotor angle detector resets without a slip being counted or
•
no rotor relative movement was detected during the time
