MCS communication error
An error occurred during handshake communication between the NC and the MCS drive controllers. The character string shows the handshake error number, error data and the command/channel/network address involved.
Common Causes
- Faulty application software
- Faulty MCS software
Troubleshooting Steps
- 1Record the full character string: the 2-digit handshake communication error number, 8-digit error data, and the command name, channel number and network address of the controller involved.
- 2Check which MCS unit sits at the network address shown and inspect its LEDs for abnormal status.
- 3The manual lists faulty application software or faulty MCS software as the causes, so after noting versions, reload or update the application software first.
- 4If the error continues, update or replace the MCS software on the affected controller as the manual directs.
- 5If it returns after these checks, record the alarm number, code and object and contact Okuma service.
