Maybe because the motor itself seems to be oversized for what the application needs so it never needs 100% torque. @LionelHutz If I set the VFD...

    Configure Variable Torque VFD to run a Constant Torque Motor

    I designed an MCC panel which has this 75hp VFD (Normal Duty) and after getting an Overload fault on the VFD, it just dawned on me that the application needs constant torque. What can I do to salvage this situation before giving up and replacing the VFD? If let's say I decide to operate the VFD...
