LEDs Signalling

Overview

Onboard LEDs can be used to retrieve information on each drive’s operational state. Even if the LEDs are hidden from sight in the final application, their inclusion still provides valuable visual help during the development stage and troubleshooting or debugging afterward.

The following diagram represents the physical location of each LED on the TOP side of the proposed design:

LED	Type	Color	Description
EtherCAT Link IN/OUT	Single	Green	EtherCAT input and output link LEDs: IN: Axis A Port 0 Link LED OUT: Axis B Port 1 Link LED
Axis A/B RUN/ERROR	Bi-color	Green / Red	EtherCAT status (ECAT Status) Green: RUN LED. Red: ERROR LED.
Axis A/B FAULT	Single	Red	Drive FAULT State (Drive status) LED is on when an error event has occurred and the drive is trapped in the Fault state.
Axis A/B Logic Supply	Single	Orange	Drive’s +3.3 V internal supply (CAP-NET pin 14. Indicates the logic circuits of the drive are supplied.
