6.2.3 Last Trip Data
These messages describe the motor status at any given point in time. If the motor has
been tripped and the 469 has not yet been reset, the MOTOR STATUS value will be “Tripped”.
The MOTOR THERMAL CAPACITY USED reflects an integrated value of both the Stator and
Rotor Thermal Capacity Used. The values for ESTIMATED TRIP TIME ON OVERLOAD appear
whenever the 469 picks up on the overload curve.
