4.10 Selecting a Frequency Command Source
The frequency command source by factory default is the keypad ( / keys). This section provides the frequency
command setting procedures using the frequency command sources of the keypad, external potentiometer, and
frequency selection terminal commands.
4.10.1 Setting up a frequency command from the keypad
Follow the procedure given below.
(1) Configure the function codes as listed below.
Function
code
Name Function code data Factory default
F01 Frequency Command 1 0: Keypad ( / keys) 0
• When the inverter is in Programming or Alarm mode, frequency command setting with / keys
is disabled. To enable it, switch to Running mode.
• 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.
When you start specifying the frequency command with the / key, the least significant digit on the
display blinks; that it, the cursor is located in the least significant digit. Holding down the / key changes
data in the least significant digit and generates a carry, while the cursor remains in the least significant digit.
(4) To save the new setting into the inverter's memory, press the key.
