4.11 Selecting a Frequency Command Source
Factory default run commands are set from the keypad. A setting example for frequency command input methods
other than this is shown below.
4.11.1 Setting the frequency from the keypad
Follow the procedure given below.
(1) Configure the function codes as listed below.
Table 4.11-1
0: Keypad operation ( / keys)
• When the keypad is set to Programming or Alarm mode, the / keys are disabled to modify the
reference frequency. You need to switch to Running mode to enable frequency setting with the /
keys.
• If any of higher priority frequency command sources (multistep frequency commands and frequency
commands via communications link) is specified, the inverter may run at an unexpected frequency.
(2) Press the / key to display the current frequency command on the LED monitor. The least significant
digit blinks.
(3) To change the frequency command, press the / key again.
If the frequency command is set with the / keys, the least significant digit displayed flashes and the
data is changed from the least significant digit and the changing digit gradually shifts to the upper digit.
• In order to specify settings such as the reference frequency, press the / key once, and when
the rightmost digit flashes, press the key. The flashing digit will then move, making it easy to
change large values.
(4) To save the new setting into the inverter's memory, press the key.
For details on how to modify the function code data, see Chapter 3 “3.4.1 Setting up function codes “Data
Setting””.
