Chap. 3 OPERATION USING THE KEYPAD
3.2 Running Mode
If the inverter is turned ON, it automatically enters Running mode in which you may:
(1) Run/stop the motor
(2) Set up the reference frequency and PID process command
(3) Monitor the running status (e.g., output frequency, output current)
(4) Jog (inch) the motor
3.2.1 Run/stop the motor
By factory default, pressing the key starts running the motor in the forward direction and pressing
the
key brings the motor to a decelerated stop. The key is enabled only in Running mode.
Changing function code F02 data makes it possible to run the motor in the reverse direction by
pressing the
key, determine the motor rotational direction by entering input signals to the terminals,
and control the motor by pressing
/
keys.
3.2.2 Set up the reference frequency and PID process command
By using the potentiometer and
/
keys on the keypad, you may set up the desired reference
frequency and PID process command. It is also possible to set up the reference frequency as frequency,
load shaft speed, line speed, and constant feeding rate time by setting function code E48.
Setting up the reference frequency
With the potentiometer on the keypad (factory default)
If you set function code F01 to "4: Potentiometer on the keypad" (factory default) and select frequency
setting-1 with function codes E01 through E03 (Hz2/Hz1 = OFF), then the potentiometer becomes
enabled to set up the reference frequency. Setting function code C30 to "4: Potentiometer on the
keypad" and selecting frequency setting-2 (Hz2/Hz1 = ON) also produce the same effect.
With
/ keys
If you set function code F01 to "0: Keypad operation" and select frequency setting-1, then
/
keys become enabled to set up the reference frequency in Running mode. In any other operation
modes, those keys remain disabled.
Pressing
/
keys calls up the reference frequency with the lowest digit blinking. Pressing
/
keys again makes it possible to change the reference frequency. The new setting will be saved
internally. Even if the inverter is switched to any other frequency entry method and then returned to
the keypad entry method, the setting will be retained.
Further, even turning OFF the inverter will automatically save the setting into the non-volatile
memory. At the next time when the inverter is turned ON, the setting will become the default
frequency.
If you set function code F01 to "0: Keypad operation" but do not select frequency setting-1, then
/
keys cannot be used for setting up the reference frequency. Pressing those keys will just display the
currently selected reference frequency.
To set up the reference frequency from any other displayed items, it is dependent on function code E48
data (= 4, 5, or 6) "LED monitor details (Select speed monitor)" as listed in the following table.
