6.4 MEANING OF THE LEDS
Function of the LEDs
There are four LEDs on the front panel of the CU310-2 PN's housing (see CU310-2 PN Interface Overview,
Figure 13).

Encoder current supply > 5 V (TTL/HTL)
MOD
Operating mode (reserved)
The various LEDs are switched on and off as the control unit is powered up (depending on the phase the
system is currently in). When switched on, the color of the LEDs shows the status of the corresponding
power-up phase (see Behavior of the LEDs during booting).
In the event of a fault, power up will be ended in the corresponding phase. The LEDs that are switched on,
retain their color at this particular instant in time, so that the fault can be determined based on the
combination of LEDs that are switched on (bright) and switched off (dark).
All the LEDs go out briefly if the CU310-2 PN has powered up without error. The system is ready for
operation when the LED "RDY" is permanently green.
All the LEDs are controlled by the software loaded during operation (see Behavior of the LEDs in the
operating state).
