W7 ASD Installation and Operation Manual 25
Electronic Operator Interface
The W7 ASD 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 18 on pg. 26.
The EOI can be mounted remotely from the ASD as described in the section titled EOI Remote Mounting
on pg. 27. The dimensional requirements for remote mounting may also be found there. Using a screw
length that exceeds the specified dimensions may cause deformation of the outer surface of the bezel as
shown in
Figure 21 on pg. 29 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, output power, etc.), and diagnostic information.
Local|Remote 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|Remote Key may be switched between the
Local and Remote modes while at the Frequency Command screen only.
The Local Command mode enables 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 any
one of the following methods:
• Pulse Input,
•Motorized Pot,
• Communication Card,
• RS232/RS485,
• Common TTL,
• Binary/BCD,
• LED Keypad,
• Option Card RX2,
•RX,
•RR, or
• VI/II.
The input channel selection may be made via Program Utilities Command and Frequency
Settings.
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 Communication
Command 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 menu-specific.
Run Key — Issues the Run command while in the Local mode. A Run command issued from the EOI
while in the Remote mode will be activated once the Local mode is selected and the motor will run at the
commanded speed.
Run Key Status LED — Illuminates green while stopped or red while running.
Stop Key — If pressed once while in the Local mode issues the Off command and decelerates the motor
at the programmed rate until it stops. If pressed twice in rapid succession initiates an Emergency Off
(terminates the ASD output and applies the brake if so configured) from the Local or Remote modes.
