Motor ON/OFF
For convenience and safety reasons, the power to the motors can be con-
trolled separately. This is done from the front panel through two buttons
labeled MOTOR E n and MOTOR IBM .
A green LED on top of the MOTOR N M provides a quick visual indication
of the motor Power ON condition.
The MOTOR ESN button is a normally closed switch wired in series with
the two Motor Interlock switch connections on the rear panel. For the
motors to turn on, the entire circuit must be closed.
Numeric Keypad
On the right hand side of the front panel there is a 12-button numeric key-
pad. Depending on the mode the controller is in, this keypad can be used
for numerical data entry or controlling the manual JOG mode.
For details on using the keypad for jog control see Section 2. Local Mode.
Function Keys / Display
The central part of the front panel is occupied by a large display and four
function keys. The display is a six-line back-lit LCD which shows both menu
and status information.
Below the display are four function keys. Their context-sensitive functions
are always given on the bottom line of the display window.
The contents of the display window are described in detail in Section 2.

Display Organization
The display has six lines with a maximum of 30 characters each. For better
visibility, the characters are bright on a dark background. Information is
highlighted using dark characters on a bright background.
On the right of the function keys, 2 screws permit to adust the contrast and
the brightness of the display.
The bottom line of the display, line number 6, is reserved exclusively for
defining the four function keys.
The next line up, line number 5, is primarily used to display messages, defi-
nitions o r other helpful information. It generally displays information in
reverse mode.
