8. OF OPERATION Harmonic Compensation The MX motor overload calculation automatically compensates for the additional motor heating that can result from the presence of harmonics Harmonics can be generated by other loads connected to the supply such as DC drives AC variable frequency drives arc lighting uninterruptible power supplies and other similar loads Hot Cold Motor Overload Compensation If a motor has been in operation for some time it will have heated up to some point Therefore there is typically less overload content available in the case where a motor is restarted immediately after it has been running when compared to the situation where a motor has been allowed to cool down before restarting The MX provides adjustable hot motor overload compensation to fully protect the motor in these cases If the hot and cold maximum locked rotor times are provided the MX Hot Cold Ratio parameter value can be calculated as follows If no motor information is available a Hot Cold ratio value of 60 is usually a good starting point OL H C Ratio 1 Max Hot Locked Rotor Time x 10094 Max Cold Locked Rotor Time The adjusts the actual motor overload content based on the programmed Hot Cold Ratio set point and the present running current of the motor so that the accumulated motor overload content accurately tracks the thermal condition of the motor If the motor current is constant the overload content eventuall

TE When setting a current limit the motor must be monitored to ensure that the current is high enough to allow the motor to reach full speed under worst case load conditions Ramp Time 7 THEORY OF OPERATION The ramp time is the time it takes for the current to go from the initial current to the maximum current To make the motor accelerate faster decrease the ramp time To make the motor accelerate slower increase the ramp time If the ramp time expires before the motor reaches full speed the starter maintains the maximum current level until either the motor reaches full speed the Up to Speed time expires or the motor thermal overload trips 3 NOTE Setting the ramp time to a specific value does not necessarily mean that the motor will take this time to accelerate to full speed The motor and load may achieve full speed before the ramp time expires if the application does not require the set ramp time and maximum current to reach full speed Alternatively the motor and load may take longer than the set ramp time to achieve full speed 7 3 2 Programming A Kick Current General Kick Level Kick Time The kick current sets a constant current level that is applied to the motor before the ramp begins The kick current is only useful on motor loads that are hard to get rotating but then are much easier to move once they are rotating An example of a load that is hard to get rotating is a ball mill The ball mill requires a high torque
