SI-F/G Communication Error Detected

What does E-15 mean?

A communication error has occurred when the SI-F/G Option Card is designated as the source for run commands or frequency reference (b1-01=3 and/or b1-02=3), and communication with it is lost. This implies a failure in the communication link or configuration with the SI-F/G card. Without proper communication, the Drive cannot receive critical commands or references, leading to a stop.

• Loss of physical connection to the SI-F/G option card or damage to the communication cable.
• Incorrect communication protocol or address settings (e.g., P5-01, P5-02 for network address) on the SI-F/G card or the master device.
• Excessive network traffic or electromagnetic interference causing data corruption or timeouts on the communication bus.
• The master device (e.g., PLC) stops sending commands or reference signals to the SI-F/G card.
• Hardware malfunction of the SI-F/G option card, preventing it from processing communication.

Click steps to track your progress.

1. 1

   Inspect the communication cable (e.g., Ethernet, DeviceNet, Profibus) connected to the SI-F/G option card for secure connections and physical damage.

2. 2

   Verify the communication parameters (e.g., P5-01, P5-02, P5-03) on the Drive's SI-F/G card match the settings on the master controller.

3. 3

   Confirm the master controller (e.g., PLC) is active and sending run commands/frequency references as expected to the SI-F/G card.

4. 4

   Temporarily cycle power to the Drive and the master controller to reset communication modules.

5. 5

   Check for network activity lights (e.g., Link/Act LEDs) on the SI-F/G card itself to confirm physical layer communication.
