Speed Search Retry Error

What does 3021 mean?

The speed search function has attempted to retry more times than allowed by the b3-19 parameter. This typically indicates that the speed search settings in b3-17 and b3-18 are not correctly configured for the application, preventing successful speed identification within the set limits.

Complete Troubleshooting Guide

1. 1

   Review and adjust the parameters b3-17 (Speed Search Acceleration Time) and b3-18 (Speed Search Deceleration Time) to appropriate values for the motor and load characteristics.

2. 2

   Check parameter b3-19 (Number of speed search retrials) to ensure it's not set too restrictively, allowing for sufficient attempts.

3. 3

   Verify that the motor and load conditions are suitable for speed search operation, ensuring no mechanical issues or unexpected resistances.
