[Cause]
The tracking time exceeds the specified time and the soft floating function has been disconnected. (When $SFLT_ERRTYP=0 is used) The number in parentheses indicates the action group number.
[Countermeasure]
1. Check whether external force has been applied before soft float starts.
2. Check whether an action that changes the posture significantly is performed while soft float is enabled.
3. Increase the value of system variable $SFLT_FUPTIM as needed.
