3.5 LEDs and signalling
Four status LEDs in the cover indicate the various states of the encoder and support
diagnosis and troubleshooting in the field (see Table 3.2). The two Link Activity LEDs
(L/A) light up or flash green if the encoder is connected to another EtherCAT node
(SPS, switch, other field device, etc.) and data is being exchanged. The MOD LED
indicates operation, always lighting up green when the supply voltage is connected.
The STAT LED indicates the EtherCAT status. Red signals in the STAT LED indicate
errors, while green ones indicate the bus status. The green signals are always
displayed in the pause between the red signals. This means that, in the event of
uncertainty, the red signals take priority.
