B809 ~ B816 M variable compensation table
When carrying out constant output operation, the fluctuation compensation for the excitation
inductance is adjusted in this mode, however, the motor will rotate to the maximum speed during
automatic tuning, so special attention must be paid to safety.
Abnormal completion of automatic tuning
- If automatic tuning ends abnormally, the "FLT" LED will turn ON and the display will blink with the
message “Auto Tune Abnormal”.
- Investigate and check according to the error codes.
- In case of error, the error code will be displayed in addition to the progress at the time of error. For
example, if the error comes at 50% progress with an error code 12, then M303 will display 125. The
first two digits display the auto tune error code.
Error code during automatic tuning
Error Code Significance of error code
01
Problem in current sensor circuit, may be loose connection, faulty current sensors,
wrong sensors used.
03
04 Over current condition has occurred during the auto tuning process.
12 Under voltage condition has been detected during the auto tuning process.
The other error codes are for internal diagnosis and debugging purpose.
4-4 Test operations
When finished with automatic tuning, test run the isolated motor, and make sure that there are no
errors.
Use Digital Operation Panel mode to test run the motor. Initially set 10.0Hz and press “RUN” key to
start the motor.
