Electronic Operator Interface
The G7 Electronic Operator Interface (EOI) is comprised of an LCD display, two LEDs, a rotary encoder, and eight keys. These items are described below and their locations are provided in Figure 19 on pg. 37.
The EOI can be mounted remotely from the ASD as described in the section titled EOI Remote Mounting on pg. 190. The dimensional requirements for remote mounting may also be found in this section. Using a screw length that exceeds the specified dimensions may cause deformation of the outer surface of the bezel as shown in Figure 31 on pg. 192 and should be avoided.
The interface can operate up to distances of 15 feet from the ASD via the Common Serial (TTL) Port. For distances beyond 15 feet, the RS232/RS485 port is recommended.
EOI Features
LCD Display — Displays configuration information, performance data (e.g., motor frequency, bus voltage, torque, etc.), and diagnostic information.
LocalRemote Key — Toggles the system to and from the Local and Remote modes. The LED is on when the system is in the Local Command mode. The Local mode allows the Command and Frequency control functions to be carried out via the EOI.
The Remote mode enables the Command and Frequency control functions to be carried out via the Control Terminal Strip, LED Keypad, RS232/RS485, Communication Card, or Pulse Input. The selection may be made via Program ⇒ Fundamental Parameters ⇒ Standard Mode Settings ⇒ Command
Mode.
Note: The LED Keypad is under development and is unavailable at the time of the release of this manual.
The availability of the Local mode of operation (Command and Frequency control) may be disabled via Program ⇒ EOI Option Setups ⇒ Local/Remote Key. The availability of the Local mode of operation may be reinstated by changing this setting or performing a Reset (see F007).
Enter Key — Selects a menu item to be changed or accepts and records the changed data of the selected field (same as pressing the Rotary Encoder).
Esc Key — Returns to the previous level of the menu tree, toggles between the Panel and the Frequency Command screens, or cancels changes made to a field if pressed while still in the reverse video mode (dark background/light text). The 3 functions are
Run Key — Issues the Run command while in the Local mode.
Run Key Status LED — Illuminates green while stopped or red while running.
Stop Key — Issues the Off command (decelerates to Stop at the programmed rate) if pressed once while in the Local mode or initiates an Emergency Off (terminates the ASD output and applies the brake if so configured) if pressed twice quickly from the Local or Remote modes.
Up Key — Increases the value of the selected parameter or scrolls up the menu listing (continues during
Down Key — Decreases the value of the selected parameter or scrolls down the menu listing (continues during
