  • Page 39: Time Dependent Overload Curve

    Overload Curves 2.11. Time dependent overload curve If the load current exceeds the rated current but is below the overcurrent level, an overload timer begins counting. The rate at which the timer increments is a function of load current. The higher the current the faster the increments. When the counter reaches the limit the Error Overload (E.OL) fault is triggered and the output to the motor is shut off.

    PWM. As a result, the continuous output current must be limited at low speeds to prevent the power transistors from overheating. The Torqmax F5 will drop the carrier frequency to 4kHz if necessary to be able to continue to provide current to the motor. Once the output frequency rises above low frequency or the current drops below the levels listed below, the carrier frequency will be returned to the higher value.
