4.8 Configuring Function Codes for Drive Controls
4-23
■ Tuning procedure
1) Set function code P04* to “1”, “2”, or “5”, and press the key.
(The 1, 2, or 5 indicator will blink slowly.)
2) Enter a run command.
(The factory default is forward rotation with the keypad key.)
To switch to reverse rotation or to select the terminal signal FWD or REV as a run
command using the keypad, change the data of function code F02.
3) By entering a run command, tuning is started, and the progress status is displayed
as a percentage (%).
4) In the case of function code P04* = 2 (rotation tuning), after the tuning in 3) above
is complete, the motor is accelerated to approximately 50% of the base frequency
and then tuning starts. After measurement, the motor decelerates to stop.
5) If the terminal signal FWD or REV is selected as a run command (F02 = 1), “end”
appears upon completion of measurement. Turning the run command OFF
completes the tuning.
If the run command has been given through the keypad or the communications
link, it automatically turns OFF upon completion of the measurements, which
completes the tuning.
6) Upon completion of the tuning, the subsequent function code appears on the
keypad.
The initial setting for the speed regulator (ASR) is rather low to prevent hunting. However, hunting may
occur during tuning due to mechanical conditions. If so, a tuning error (Er7) or speed mismatch (ErE)
may occur. When Er7 occurs, lower the speed control gain, and when ErE occurs, cancel the speed
mismatch detection (d23 = 0), and then perform tuning again.
(The subsequent function
code appears)
