LED and 7-segment LED

LED and 7-segment LED Display

The Controller has 4 LEDs and a 4-digit, 7-segment LED

• LED
  The LED (TEST, TEACH, AUTO, PROGRAM) corresponding to the current operation mode (TEST, TEACH, AUTO, PROGRAM) lights up.
• 7-segment LED
  This displays line numbers and the Controller status (error number, warning number, emergency stop, and safeguard status).

From immediately after power-on until Controller startup

• LED
  All four LEDs blink.
• 7-segment LED
  All 4-digit 7 segments are turned off.

After Controller startup

• LED
  The LEDs (TEST, TEACH, AUTO, PROGRAM) corresponding to the current operation mode (TEST, TEACH, AUTO, PROGRAM) turn on.

• 7-segment LED
  The displayed information changes depending on the Controller status.
  If several Controller conditions occur at the same time, the displayed information on the top row takes precedence. For example, if an "emergency stop state" and a "safeguard open state" occur at the same time, the following display will appear.
