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.

those terminals OFF and then change the F0

1 data.

(2) Connect an external potentiometer to terminals [11] through [13] of the inverter.
