SI-F/G Communication Error

What does E-15 mean?

This fault may occur when using the SI-F or SI-G communication options if communication is lost after being established. It signifies a disruption in data exchange with the specific option card (SI-F or SI-G), which can halt control functions or data exchange, leading to operational stoppage and loss of control.

• Damaged or loose communication cable connected to the SI-F/G option card (e.g., EtherCAT, PROFINET, DeviceNet).
• Incorrect network configuration (e.g., IP address, subnet mask, device name, scan time) for the SI-F/G card.
• Faulty SI-F or SI-G communication option card itself.
• Interference on the communication network (e.g., electromagnetic noise, incorrect grounding).
• Mismatched firmware versions between the inverter and the SI-F/G card or the master controller.

Click steps to track your progress.

1. 1

   Inspect physical connections of the communication cable (e.g., RJ45 for EtherCAT/PROFINET) at the SI-F/G card and the network switch/PLC.

2. 2

   Verify network parameters (e.g., IP address, DeviceNet MAC ID, EtherCAT Node Address) on the SI-F/G card and the master controller.

3. 3

   Check LED indicators on the SI-F/G card for network status (e.g., LINK/ACT, MS, NS LEDs).

4. 4

   Temporarily connect the SI-F/G card directly to a configured master controller (PLC/PC) to bypass network infrastructure issues.

5. 5

   Confirm the firmware version compatibility of the SI-F/G card with the inverter firmware using the inverter's display.
