Fatal Error (Safety Technology Initialization)

What does F8203 mean?

This is a fatal error specifically tied to the drive's safety technology during initialization. When F8203 occurs, the closed-loop or open-loop U/f control of the drive is no longer guaranteed. The drive immediately switches off, becoming torque-free, overriding settings in P-0-0119 and P-0-0117. This error requires a complete recommissioning of the safety technology.

• An error condition detected within the drive's safety technology system during initialization.
• Safety technology requires complete recommissioning.

Click steps to track your progress.

1. 1

   Switch the drive off completely.

2. 2

   Recommission the safety technology completely.

3. 3

   Clear the error message using command S-0-0099 (C0500 Reset class 1 diagnostics). This may require switching to parameter mode or a complete drive power cycle.

4. 4

   Ensure the drive is in operating mode and power is switched on ("Ab").

5. 5

   Switch on drive enable again (0-1 edge).

6. 6

   If this fatal error recurs repeatedly, replacement of an entire component (e.g. motor or drive controller) may be necessary.
