The hottest measured inverter IGBT module temperature is displayed as
x.x degrees C.
Accumulated percentage of drive overload. Continuously operating the drive
over 100% of its rating increases this value to 100% and causes a Drive OverLoad
fault (fault 64).
Accumulated percentage of motor overload. Continuously operating the motor
over 100% of Motor OL Amps (48) increases this value to 100% and causes a
Motor OverLoad fault (fault 7).
Displays the imbalance in current between motor phases.
If the imbalance count remains over inverter Imbalance Limit (49) for more than
inverter Imbalance Time (50), the Motor I Imbalance fault (fault 37) occurs.
The imbalance in amps is calculated as the larger of:
(largest phase current) – (average phase current), or
(average phase current) – (smallest phase current).
