Digital Operator Display (optional)

The key names and functions of the Digital Operator are described below 

„

Digital Operator Keys 

Note: Except in diagrams, Keys are referred to the key names listed in the above table. 

Key

Name

Function

LOCAL/REMOTE Key

Switches between operation via the Digital Operator (LOCAL) and the settings in 
b1-01 and b1-02 (REMOTE).
This key can be enabled or disabled by setting parameter o2-01.

MENU Key

Selects menu items (modes).

ESC Key

Returns to the status before the DATA/ENTER key was pressed.

JOG Key

Starts jog operation when the inverter is operated by the Digital Operator and d1-18 
is set to 0.

FWD/REV Key

Selects the rotation direction of the motor when the Inverter is operated by the Digi-
tal Operator.

Shift/RESET Key

Sets the active digit when programming parameters.
Also acts as the Reset key when a fault has occurred.

Increment Key

Selects menu items, sets parameter numbers, and increments set values. 
Used to move to the next item or data.

Decrement Key

Selects menu items, sets parameter numbers, and decrements set values. 
Used to move to the previous item or data.

DATA/ENTER Key

Enters menus and parameters, and set validates parameter changes.

RUN Key

Starts the Inverter operation when the Inverter is controlled by the Digital Operator.

STOP Key

Stops Inverter operation.
This key can be enabled or disabled using parameter o2-02 when operating from a 
source different than the operator.
