Issue Details

When using an SDI plugin to connect to my EtherCAT motor drive, I receive error -77028.  What can I do to troubleshoot this?

Solution

  1. Make sure you have followed the steps in for Getting Started with SoftMotion Drive Interface (SDI).  
  2. Check to make sure your EtherCAT Master is configured to use EtherCAT on its port, instead of Ethernet.
  3. Make sure your EtherCAT cable is plugged into the specified EtherCAT port.
  4. Open the motor drive manufacturer's software.  Be sure the drive is set in position mode, and is set to accept commands over EtherCAT or CANopen over EtherCAT (CoE).
  5. Try running the SDI plugin example once more.
