EXPERT SERVO DRIVE COMMUNICATION ERROR REPAIR SERVICES

Servo drives must communicate reliably with a PLC or other motion controller to receive commands and transmit status information. Communication errors can disrupt your entire automation system. ROC Industrial provides expert repair services for servo drives experiencing communication problems, supporting a wide range of industrial communication protocols.

Common Causes of Motor Feedback Problems

  • Wiring Problems: Loose connections, damaged cables, incorrect wiring, or wiring interference.

  • Network Configuration Issues: Incorrect IP addresses, subnet masks, gateway settings, or other network configuration errors (for Ethernet-based protocols).

  • Protocol Mismatches: The drive and controller are not using the same communication protocol or settings.

  • Driver Problems: Missing, outdated, or corrupted communication drivers on the controller.

  • Hardware Failures: Faulty communication ports on the drive or controller.

  • Software/Firmware Bugs: Glitches in the drive's or controller's communication software.

  • Interference: Electrical noise or electromagnetic interference (EMI) disrupting communication.
