Q: What does Mazak parameter L121-L124 do?

L121-L124 is a Machine parameter in the TABLE group of the MAZATROL SmoothX control (INTEGREX e-670H). Software limit relative position check – Limit distance in the approaching direction L121 1st set of axes L122 2nd set of axes L123 3rd set of axes L124 4th set of axes. For arbitrary two axes that move on the same slideway, the limit of distance those axes can approach with each other is set to prevent interference. If they are going to move closer beyond the distance set at this parameter, software limit alarm is output and they stop moving. Using parameters L121 to L124, the limit distance in the approaching direction 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 closest 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, move the Z2-axis close to the W-axis, which is located at the home position, up to the position just before they interfere with each other, and set the machine coordinate of the Z2-axis located at that position. If zero is entered, the checking function in the approaching direction will be invalid. Note that the check is possible only for the combination of NC axes.

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.

What it does

For arbitrary two axes that move on the same slideway, the limit of distance those axes can approach with each other is set to prevent interference. If they are going to move closer beyond the distance set at this parameter, software limit alarm is output and they stop moving. Using parameters L121 to L124, the limit distance in the approaching direction 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 closest 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, move the Z2-axis close to the W-axis, which is located at the home position, up to the position just before they interfere with each other, and set the machine coordinate of the Z2-axis located at that position. If zero is entered, the checking function in the approaching direction will be invalid. Note that the check is possible only for the combination of NC axes.
