Chap. 3 OPERATION USING THE KEYPAD
Setting up the set frequency with / keys under the PID control
To set the set frequency with / keys under the PID control, you need to specify the following
conditions:
- Set function code F01 to "0: Keypad operation."
- Select frequency setting-1 (Frequency settings from communications link: Disabled, and Multistep
frequency settings: Disabled) as manual speed command.
- Set the LED monitor to the speed monitor in Running mode.
The above setting is impossible in any operation mode except Running mode.
The setting procedure is the same as that for usual frequency setting.
If you press
/ keys in any conditions other than those described above, the following will appear:

• When setting the frequency and others with
/
keys, the lowest digit on the display
will blink. Change the setting, starting from the lowest digit and the cursor will move
gradually to the next digit to be changed.
• When the data is to be changed rapidly, hold down the
key for 1 second or longer, and
the blinking cursor will move to the next digit where the data can be changed (curso
movement).
3.2.3 Monitor the running status
In Running mode, the seven items listed below can be monitored. Immediately after the inverter is
turned ON, the monitor item specified by function code E43 is displayed. Press the key to switch
between monitor items.

Note: The PID process command and PID feedback value are displayed only under the PID control using a process
command (J01 = 1 or 2). Further, the timer (for timer operation) is only displayed when timer is enabled (C21 = 1).
