LEDs Description of the LED function
GREEN Identical to the READY output.
OFF: No power supply or ENABLE is not activated.
ON: System is ready for operation.
Flashing: Error discovered
(depending on the SENS command)
YELLOW A
Identical to the status bit "POSWIN:S”
OFF: The axis in not inside the monitoring window
ON: Target position within the monitoring window
YELLOW B
Identical to the status bit "POSWIN:D”
OFF: The axis in not inside the monitoring window
ON: Following distance within the monitoring window
GREEN +
YELLOW 1. Chasing light (over all LEDs): The bootloader is active. No normal functions are
possible.
2. All LEDs flash shortly every 6 s: An internal data error was detected and corrected
automatically! The module still works regularly. To acknowledge the error the module
has to be cycle powered.
YELLOW A +
YELLOW B Both yellow LEDs flash oppositely every 1 s: The nonvolatile stored parameters are in-
consistent! To acknowledge the error, data has to be saved with the SAVE command or
the corresponding button in the WPC.
