• If the free V/f setting is enabled, the functions of torque boost A041/A241, base frequency A003/
A203/A303, and maximum frequency A004/A204/A304 are disabled. (Free V/f frequency 7 is
regarded as the maximum frequency.)
* Even if free V/f voltages 1 to 7 are set to 800 V, the Inverter cannot output voltage higher than
the input voltage or the value of the motor voltage selection.
Use thorough caution to verify that the output characteristic setting is proper. An improper setting
causes overcurrent during acceleration or deceleration, or vibration of the motor and/or machine.
