Setting up the set frequency with the and keys under the PID control
To set the set frequency with the and 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 the or key in any conditions other than those described above, the following will
appear:

• When setting the frequency and others with the / 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
