Q: What does Mazak parameter J251 do?

J251 is a Machine parameter in the CALL MACRO group of the MAZATROL SmoothX control (INTEGREX e-670H). Software limit relative position check – Limit distance in the separating direction J251: 1st set of axes J252: 2nd set of axes J253: 3rd set of axes J254: 4th set of axes. For any two axes that run on the same slideway, the maximum distance that those axes can be separated from each other is set to prevent damage to the way covers. If the two axes are going to be separated beyond the value set for this parameter, a software limit alarm is output to stop the axis movement. Using parameters J251 to J254, the maximum separating distances can be set for up to four axes. Set the machine coordinate of the check target axis, set at parameters L117 to L120, existing at the permissible most separated position from the check reference axis, set at parameters L113 to L116, which is located at the home position. Example : In the example shown below, if the W-axis and the Z2-axis are defined as the check reference axis and the check target axis, respectively, set the machine coordinate of the Z2-axis existing at the permissible most separated position from the W-axis, which is located at the home position. If zero is entered, the checking function in the separating direction will be invalid. Note that the check is possible only for the combination of NC axes. machine zero point machine zero point

Machine-specific. This parameter list is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (manual HA64HA0035E). Other Mazak models and control generations use different addresses, ranges and meanings — verify on your own control before changing anything.
