What to do if EtherCAT communications do not start on Omron G5 Servo Drives?
- D
  Deborah MartinezJul 28, 2025
  If EtherCAT communications do not start, several factors could be at play. First, verify that ECAT[0].Enable is set to 1 by running the ECAT[0].Enable=1 command from the Terminal pane. Also, ensure that the EtherCAT network configuration in the Controller matches the physical network configuration. Check that the Ethernet cable is correctly connected. Finally, examine the ECAT[0].error value for any error indications.

  If the link is not established, check the following: * Replace the Ethernet cable if it is broken or not the specified type. * Reconnect any disconnected connectors on the Ethernet cable used for EtherCAT communications and ensure they are correctly mated. * If a slave within the EtherCAT network configuration has failed, replace it.

Why does a synchronization error occur at a slave in Omron G5?
- G
  gwashingtonAug 17, 2025
  A synchronization error at a slave may occur if the distribution clock is not set correctly, so review the settings. Another potential cause is the servo task processing time exceeding the set period; in this case, review the program or servo frequency to adjust it, ensuring the servo task processing time does not exceed the period.
