UL approved for solid state motor overload protection Therefore a separate thermal overload relay is not required for single motor applications The MOTOR OVERLOAD circuit is used to protect the motor from overheating due to excessive current draw The trip time forthe MOTOR OVERLOAD setting is based on what is known as an inverse t function This function allows the drive to deliver 150 of the rated output current for one minute and even higher current levels for shorter periods of time Once the overload circuit times out the drive will trip into an OVERLOAD fault The MOTOR OVERLOAD should be set to a value which is equal to the ratio in percentage of the motor full load current rating to the drive output current rating This will result in an overload capacity of 150 of the MOTOR current rating for one minute If this parameter is set to 100 the motor will be allowed to draw 150 of the DRIVE output current rating for one minute This distinction is important in cases where the motor full load current rating is significantly less than the drive output current rating such as applications where the drive is oversized to meet torque requirements Example 1 A 5 Hp 480 Vac drive is operating a 3 HP motor with a full load current rating of 4 8 amps Divide the motor current rating by the drive output current rating 4 8 7 6 63 Entering this value will allow continuous operation at 4 8 amps and will also allow the motor to draw
