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.

Complete Troubleshooting Guide

1. 1

   Inspect the physical communication signals and wiring to the SI-F/G option card for proper connection and integrity.

2. 2

   Verify that parameters b1-01 (Run Command Source) and b1-02 (Frequency Reference Source) are correctly set to use the SI-F/G option card.

3. 3

   Check the setting of parameter F6-01 (Communication Option Selection) to ensure it matches the installed SI-F/G card type.

4. 4

   Review and confirm the communication configuration on the host side (master controller) for compatibility and correct protocol settings.
