Phase A (L1) Motor Current Scaled. Scaled by parameter "I Scale
Factor".
Phase B (L2) Motor Current Scaled. Scaled by parameter "I Scale
Factor".
Phase C (L3) Motor Current Scaled. Scaled by parameter "I Scale
Factor".
Average motor Current Scaled. Scaled by parameter "I Scale Factor".
This scale factor is applied to all current values monitored via a
communication network.
Motor Current Unbalance Percent
Motor Residual Ground Fault scaled current RMS. Scaled by parameter "I
Scale Factor".
Thermal Capacity in Percent - An overload trip occurs when the Thermal
Capacity reaches 100%.
Estimated Time for Overload to Reach Trip Threshold (100% Thermal
Memory)
Thermal Capacity (Percent) Remaining to Trip
Time for overload to reach reset threshold. The Thermal Memory must
drop below 75% (default value) before a reset is allowed.
