LEDs
Diagram 5: Organisation of the robot control and LED signal lights of the individual modules.
After the power supply is established, the green LEDs of all modules light up. Approximately
20-30s later, the green LEDs of the motor and IO modules start flashing, which means that the
control computer has established communication with the modules. The control system is now
ready to receive commands.
Since the motors are not yet activated, the red LEDs of the motor modules light up.
The yellow LED on the motor modules lights up when the axis' reference switch is triggered.
As soon as the emergency stop is activated (pulled out), the red LED on the support module
goes out.
After "Reset" followed by "Enable" have been pressed using display control, the red LEDs on
the motor modules also go out.
The yellow LEDs of the Digital In/Out modules light up briefly when the status of an input or
output changes.
For the detailed meaning of the LEDs, see the table in the section 11.
