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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

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

2. 4
