Speed Search Retries Exceeded

The speed search-related parameters are set incorrectly.

  • Decrease b3-10 [Speed Estimation Detection Gain].

  • Increase b3-17 [Speed Est Retry Current Level].

  • Increase b3-18 [Speed Est Retry Detection Time].

  • Do Auto-Tuning again.

The motor is coasting in the opposite direction of the Run command.

Set b3-14 = 1 [Bi-directional Speed Search = Enabled].
Note:

  • The drive detects this error if the number of speed search restarts is more than b3-19 [Speed Search Restart Attempts].

  • Do a Fault Reset to clear the fault.
