⑥
The motor is again accelerated to approximately 50% of the base frequency and then tuning
starts. Upon completion of measurements, the motor decelerates to a stop. (Estimated tuning time:
acceleration time +20~160 + deceleration time)
⑦
After the motor decelerates to a stop, tuning continues with the motor stopped. (Tuning time: max.
20~30s.)
⑧
After measurement is completed, a run command is changed into OFF automatically. tuning is
ended.
■
If tuning while the motor is rotating cannot be selected
If the "tuning while the motor is rotating under vector control (03.04*=3)" cannot be selected due to
restrictions on the machinery, perform the "tuning with the motor stops (03.04*=1)" by following the
procedure below. Compared to the former tuning, the latter may show rather inferior performance in
the speed control accuracy or stability, perform sufficient tests beforehand by connecting the motor
with the machinery.
(1) Under the condition of motor parameters are not clear.
①
Specify the 00.04*, 00.05*, 03.02*, and 03.03* data according to the motor rated values printed on
the motor 's nameplate.
②
Specify motor parameters by obtaining the appropriate values on the datasheet issued from the
motor manufacturer. (03

③
Execute “the "tuning with the motor stops” (03
．
04* = 1)”
(2) Execution procedures to stop auto-tuning
①
Set “1”in function code 03
．
04 and press key.
②
Enter a run command. (Set key on keypad as forward running. If it takes reverse running,
please modify function code 00
．
02).
③
Enter a run command, it starts tuning with the motor stopped (Tuning time: max. 40s)
④
Automatically turns the run command OFF to complete tuning.

Auto-tuning errors
Remove the error cause, Refer to the basic function parameters of V/f Control / Common Dynamic
Torque Vector Control to set and auto-tuning. ■ <1> Auto-tuning errors
Note: The default value of the speed regulator is set low to prevent your system from oscillation
(hunting). However, hunting may occur during tuning due to machinery-related conditions, causing a
tuning error

or a speed mismatch error(ErE). If a tuning error (Er7) happens, reduce the gain
for the speed regulator; if a speed mismatch error (ere) occurs, cancel the speed mismatch detection
function (09.23=0). After that, perform tuning again.
