Stall Prevention (Overcurrent)

What does Stall prevention (overcurrent) mean?

The overcurrent stall prevention function has been activated. This warning indicates that the motor is encountering excessive current, possibly due to overload, insufficient acceleration time, improper torque boost settings, or mechanical binding. While a warning, prolonged activation can lead to motor or inverter damage.

Complete Troubleshooting Guide

1. 1

   Increase or decrease the Pr. 0 Torque boost setting by 1% and observe the motor's operational status.

2. 2

   Set a larger value in Pr. 7 Acceleration time and Pr. 8 Deceleration time to allow for smoother, less current-intensive transitions.

3. 3

   Reduce the mechanical load weight on the motor or consider switching to General-purpose magnetic flux vector control if applicable.

4. 4

   Adjust the Pr. 13 Starting frequency setting and change the Pr. 14 Load pattern selection setting.

5. 5

   Set an appropriate stall prevention operation current in Pr. 22 Stall prevention operation level, or increase the level, or disable stall prevention using Pr. 156 Stall prevention operation selection (use with caution).
