CE3 Communication error at process data input object CAN3_IN

¿Qué significa x064 ?

A communication error has occurred with the process data input object CAN3_IN. This can be due to issues with the CAN bus, wiring, or incorrect data configuration. The monitoring time for this communication channel can be set with parameter C0357/3.

• Loose connections or corrosion at the CAN bus terminals (CAN_H, CAN_L) for CAN3_IN on the drive or peripheral devices.
• Electrical interference affecting the CAN3 bus due to improper cable routing near power cables or lack of shielding.
• Incorrect CAN node ID (P5-08) configuration, resulting in an address conflict on the CAN3 network.
• Mismatch in CAN bus baud rate (P5-09) between the drive and other devices connected to CAN3.
• Faulty transceiver chip on the drive's CAN3 interface or on a connected CAN device causing communication errors.

1. 1

   1. Power down the drive, re-torque all connections at the CAN3_IN terminals on the drive and at connected devices.

2. 2

   2. Relocate CAN3 bus cables away from high-current power cables and ensure proper shielding is terminated to ground.

3. 3

   3. Verify the CAN node ID (P5-08) for the drive and all devices on the CAN3 network are set uniquely.

4. 4

   4. Confirm the CAN bus baud rate (P5-09) setting on the drive matches the master controller for CAN3.

5. 5

   5. Test communication with a minimum number of devices on CAN3, systematically adding devices to identify the problematic node.
