Opposite Rotation Deceleration Fault

What does E.11 mean?

During torque control under Real sensorless vector control, if the speed command and estimated speed directions differ when reversing, the motor may not decelerate correctly at low speeds. This leads to an overload condition, shutting off the inverter output. This protective function is specific to Real sensorless vector control and prevents motor overcurrents.

Complete Troubleshooting Guide

1. 1

   Modify the control strategy to prevent rapid switching of the motor's rotation direction from forward to reverse (or vice versa) during torque control under Real sensorless vector control.

2. 2

   If operational adjustments do not resolve the issue, contact your sales representative for further assistance.
