USP (Unattended Start Protection) Error

What does E13 mean?

This fault occurs when the Unattended Start Protection (USP) function is enabled and a Run command is present simultaneously with the application of power. It prevents the motor from unexpectedly starting upon power-up, requiring deliberate action to clear the fault and resume operation, enhancing safety.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If the USP function is not desired for your application, consider disabling it via the relevant parameter.

2. 4
