A66

A66 indicates .

Cause analysis:

1. Communication cable problem;

2. A problem with the drive communication parameter settings (Pn703, Pn704);

3. Master station communication parameter setting problem;

4. External interference;

5. Drive problem;

6. The controller IP has been lost, but the intime IP has not.

Remedy:

1. Check whether the drive communication cable is securely connected and whether the ports are correct (CN3 input, CN4 output);

2. Confirm that the robot controller starts normally and that the communication parameters are set correctly;

3. Check whether drive communication baud rate parameter Pn703 and communication node parameter Pn704 are set correctly;

4. The PE conductor of the robot power cable must be safely and reliably grounded;

5. Check whether CN4 on the last drive has a network plug with a terminating resistor connected. Ensure the connection to prevent interference;

6. Confirm whether there is a drive problem by swapping drives.

7. Use VNC to change the controller IP.
