ST300 Series | E14, what does this message mean, and what can be done?

If the error message E14 appears on the frequency converter display, it indicates a phase loss on the output side.

Causes:
Phase loss at the U/V/W output or asymmetry in the motor’s three phases.
The output cables are disconnected or shorted to ground.

Solutions:
Check the motor for phase symmetry and test the cables for continuity.
Inspect the output wiring and the motor for ground faults and check the terminal screw torque.

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