Possible error codes
For this function block, the following values, among others, are possible for the ErrorId output:
Error(Hex) | Error(Dec) | Error type | Description |
|---|---|---|---|
0x8145 | 33093 | Function Block | Mapping of cyclic interface between NC and PLC is missing (e.g., AXIS_REF, AXES_GROUP_REF, ...). A reference used by the function block (e.g., to an axis, group, mover or other motion object) is not linked to the corresponding NC object, or its cyclic mapping is incomplete. |
0x8151 | 33105 | State | Command is not allowed in current axis state. If the axis has no controller enable, is in error or has been added to a group, some commands are not permitted. |
