FB error: order not allowed, because axis is in unallowed state.
Description | Before a job for an axis is sent to the motion controller, it is checked if the job is allowed. If this error message is output, the axis is in a state that is unknown and therefore not allowed. Note: The PLCopen specification defines an axis state graph that defines states for an axis controlled by PLCopen function blocks. Furthermore the diagram there defines which PLCopen commands change the actual axis state and which PLCopen commands are allowed for the actual state of the axis.
Response | Class | - | The "Error" and "ErrorID" outputs of the function block indicate the error situation. Function block is able to command a new job in the next PLC cycle.
Solution | Class | - | Please contact your motion control supplier and mention the error number.
Error type | -
