Motor and V/f Pattern Setup
After the completion of autotuning, set E1-04 (Max. output frequency) to the base frequency from the motor’s
nameplate.

Fig 5.52 Motor Base Frequency and Inverter Input Voltage Setting
When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03 (Motor
rated voltage) to the input power supply voltage × 0.9. In this case at high speeds the output current will
increase as the input power supply voltage is reduced. Be sure to provide sufficient margin in the Inverter current.

•Precautions after Rotating and Non-rotating Autotuning
If the maximum output frequency and base frequency are different, set the maximum output frequency
(E1-04) after autotuning.
