Precautions for Correct UsePrecautions for Correct Use
Even if the Free V/f Voltage 1 to 7 are set to 800 V, the inverter cannot produce output voltage
higher than the input voltage or the value of the Motor Rated Voltage Selection (A082).
Be sure to check that the output characteristic setting is proper. An improper setting causes
overcurrent during acceleration or deceleration, or vibration of the motor and/or machine.
