Following error

Following error

We have a customer with a MC664x that has an issue with FE in a master axis.
The machine is a printer and the axis is a rotary axis controlled by speed.
The FE_LIMIT is configured at maximum value (4.0e17).
He sends a video where we can see how FE is increasing to great values until the controller collapses and is not possible to stop, motor runs without control, and only the emergency stops are effective.

He uses a "FORWARD" function to move the axis.

It seems that some concepts are wrong in configuration mode but I don't know what.

We could see DPOS moveing + and MPOS moving -. suggest that they have the encoder connected the wrong way around. MPOS must be counting the same way as DPOS.
