Error handling
Error handling for gantry systems
In case of an error an intelligent drive executes an error reaction by itself in most cases and reports this to the CNC. Then the CNC can stop the other related axis.
With gantry axes, it is not permitted for one axis in the gantry combination to stop independently. This is why the CNC can stop the entire gantry combination in a controlled operation if an error occurs in one axis.
The functions for master and slave axes are set using the parameter P-AXIS-00254 (cnc_controlled_stop_after_error). A check is made whether the settings for master and slave axes are identical and this is corrected in the slave axes if necessary.
Attention
The parameter P-AXIS-00254 is currently used for SERCOS axes only.
In addition, the drive must be parameterised so that no or possibly a delayed error response is executed (see EcoDrive P-0-0117).
Notice
In a CNC-controlled error reaction the system is stopped at the defined emergency deceleration P-AXIS-00003 (a_emergency).
