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:
EtherCAT Link IN/OUT
EtherCAT input and output link LEDs:
Axis A/B RUN/ERROR
Green / Red
EtherCAT status (ECAT Status)
Axis A/B FAULT
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
Drive’s +3.3 V internal supply (CAP-NET pin 14. Indicates the logic circuits of the drive are supplied.
