①
Set “3”in function parameter 03
．
04 and press key.
②
Enter a run command. (Set key on keypad as forward running. If it takes reverse running,
Change the data of function parameter 00
．
02).
③
Enter a run command, Tuning starts with the motor stopped. (Tuning time: max. 40~75 s.)
④
The motor is 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 +20~75s + deceleration time)
⑤
After the motor decelerates to a stop, tuning continues with the motor stopped. (Tuning time: max.
20~35s.)
