Speed limit exceeded

What does 49 mean?

The motor's actual speed is outside the range defined by parameter 4-11 (Motor Speed Low Limit [RPM]) and parameter 4-13 (Motor Speed High Limit [RPM]). If the speed drops below parameter 1-86 (Trip Speed Low [RPM]) (excluding start/stop conditions), the frequency converter will trip, indicating a potential control issue or an abnormal operating condition.

Complete Troubleshooting Guide

1. 1

   Review and adjust parameters 4-11 (Motor Speed Low Limit [RPM]) and 4-13 (Motor Speed High Limit [RPM]) to match the application's required speed range.

2. 2

   Verify that the motor's operating speed is consistent with the commanded speed.

3. 3

   Check for mechanical issues on the motor or load that could cause speed deviations.

4. 4

   Adjust parameter 1-86 (Trip Speed Low [RPM]) if the low speed trip is unwanted for certain operating states.
