Causes and Fixes

In some cases, it has been observed to happen after a firmware update. To recover from this error, perform a reset to factory settings and cycle 24V supply to the drive. If the error is still on, repeat the firmware update procedure followed by a reset to factory settings and then cycle 24V supply again.

The error log and parameter file from the drive may be helpful in analyzing the problem.
