b50 ~ 55 Load Balance Function
Load Balance is a feature that automatically shares the load level between two independent motors
driving the same load. The Output Frequency of each motor is independently changed by the amount of
torque it is applying. The amount of the increase/decrease is dependent on the amount of torque being
applied.
