ST300 Series | E34, what does this message mean, and what can be done?

If the error message E34 appears on the frequency converter display, it indicates an error due to excessive speed deviation.

Causes:
The load is too high or the motor is blocked, causing excessive slip.
The stall protection has been activated.

Solutions:
Check whether the load is appropriate and, if necessary, increase the deviation limit in P11.14 or the detection time in P11.15.
Check whether the control parameters in P11.17 – P11.24 are set correctly.

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