ST300 Series | E92, what does this message mean, and what can be done?

If the error message E92 appears on the frequency converter display, it indicates that the threshold for the input voltage at analog input AI1 has been undershot.

Causes:
The input voltage or current at AI1 is too low.
Nothing is connected to AI1.

Solutions:
Check the wiring of AI1.
Check whether the threshold voltage value in parameter P08.59 is set too high.
Check whether the position of the V/I switch matches the setting in P05.52.
Set parameter P05.52 to 0 and connect AI1 directly to the +10V source for testing.

If none of these issues apply, please contact technical support.
