) The overload capability refers to the rated output currents of the MICROMASTER and MICROMASTER Vector drives as well as

the rated output currents for constant torque operation (CT) of the MIDIMASTER Vector. It is valid for a 5 minute load duty cycle.

This means that the drive units can have an overload condition of 50% for a total of 1 minute within a 5 minute period.
