Note: 1. The maximum speed is 1) 0.4kW to 7.5kW: 3600r/min, 2) 11kW to 30kW: 3000r/min, 3) 37kW to 55kW: 1950r/min.
2.Continuous, repetitive operation of 50%ED can be performed in cycle time of 10 minutes. Note that the maximum continuous operation time is 5 minutes.

5.To provide 150% torque from 0Hz to the rated speed of the motor the inverter should be one rank higher than the motor.
6.Cyclic operation when the inverter and motor have the same capacity is possible but typically only 50% torque can
be produced.
7.Continuous operation when the inverter capacity is one rank higher than the motor will produce the same results as when the inverter and motor capacity are the same (as shown above).
