Parameter Descriptions Chapter 9
Motor overload fault percent trip is visible in inverter parameter Motor OL
Count (220). The fault occurs when this parameter reaches 100%. This
parameter does not increase unless the drive output current is greater than 102%
of Motor OL Amps.
Sets the fault threshold for motor current imbalance.
If inverter Imbalance Count (221) exceeds inverter Imbalance Limit (49) for
longer than the time in inverter Imbalance Time (50), the drive faults with the
Motor I Imbalance fault (fault 37).
Sets the time delay in generating a motor current imbalance fault.
If inverter Imbalance Count (221) exceeds inverter Imbalance Limit (49) for
longer than the time in inverter Imbalance Time (50), the drive faults with the
Motor I Imbalance fault (fault 37).
Also sets the time delay in generating a Current Feedback Lost Fault (fault 35). If
this parameter is set to exactly 10.0 seconds, then the Current Feedback Lost
Fault does not occur.
Sets the method of motor torque production.
