Stall prevention

What does Stll Prev STP mean?

The running frequency has fallen to 0 due to the activation of the stall prevention function (Overload during stall prevention). This occurs when the motor is under an overload condition, causing the inverter to reduce frequency to prevent tripping.

• Motor is operating under a continuous overload condition, exceeding its rated torque.
• Mechanical binding or excessive friction in the driven equipment, leading to increased motor torque requirements.

Click steps to track your progress.

1. 1

   Reduce the mechanical load weight or process demand on the motor.

2. 2

   Verify that the motor is sized appropriately for the application's torque requirements.

3. 3

   Check mechanical components for proper lubrication and alignment to reduce friction.
