10028

Encoder not ready to operate (_ecENCODER_NOT_READY)

ABB · ACS850 Standard Program Firmware

What does 10028 mean?

This fault indicates the drive's serial encoder is not providing position data, either because it's still initializing, or its configured resolution doesn't match the drive. This will prevent axis operation, leading to a crash stop and disabling of the axis, posing a risk of uncontrolled motion if not addressed.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Connect to the drive with Mint Workbench, navigate to "Parameters > Encoder > Channel 0 > Encoder Parameter(Encoder0, Fault Register)" and check the value. If not 0, refer to the help file for ENCODERPARAMETER for specific guidance.
