N700E INSTRUCTION MANUAL
Auto Tuning
Function description
The auto tuning procedure automatically sets the motor parameters related to sensorless vector control
and automatic torque boost. Since these functions are dependent upon specific motor parameters, default
motor parameters have been set at the factory.
An auto tune is recommended before running in sensorless vector or automatic torque boost mode in
order to achieve optimal performance
Auto-Tune Procedure
Follow the steps below to auto tune the inverter, finally set the parameter H01.
1. F02, F03: Set to 30 s, the default for each parameter
2. H03: Set the motor rating
3. H04: Set the motor poles
4. A01: Set to 0 (frequency command source at potentiometer)
5. A03: Set the base frequency (default is 60Hz)
6. F01: Set the target frequency to 0Hz by turning the potentiometer all the way down. Verify this
setting by looking at the value in F01.
7. A53: Select the output voltage to the motor.
8. A33: Set to 0 (disables DC injection braking).
9. H01: Set to 1 (turns auto tuning mode on).
10. After setting above parameters, press the RUN key on the standard operator.
11. The VFD will run the auto tuning procedure on the motor. During this procedure the motor may run
up to 80% of full speed. During the auto tune you will see the following messages on the screen:
12. When you see the last screen (
a. If the display shows
13. H02: Set to 1 (uses auto tune data)
, for " OK") the auto tune has successfully completed.
instead, the auto tune has failed. Verify that the motor is wired properly
