LA104: What does the error message Err 096 mean ?

What should I do if the error message "Err 096" appears on the KONSTANTER?

Encoder blocked, error message "Err 096" appears.

This behavior occurs in conjunction with a set "lower" soft limit UL_L> 0 or IL_L> 0. Since the value "0" for USET or ISET is nevertheless permitted as a special case, however, from "0", the desired setting range can no longer be reached via incremental keys [] or incremental encoders. The lower soft limit limits can be temporarily moved or deleted. However, the simpler way is to enter numeric values ​​directly (numeric keys) with a jump to a permissible value> UL_L or > IL_L.
