• MD37140 GANTRY_BREAK_UP (For each axis)
Meaning: Gantry axis synchronization release
Setting value: 0---Synchronization
1---Synchronization released
Note: Never transfer the synchronization-released axes in the conditions
that the gantry master axis and gantry slave axis are mechanically
coupled. This may cause machinery damage.
Below is the setup process of origin setting for the gantry axis
Setup process for origin setting for the gantry axis absolute value
detection function
1. The servo drive is not supplied with power. Specify "0" with MD34210 :
ENC_REEP_STATE (origin setting status) for the both master and slave axes in order to
disable the origin setting function mode.
2. Supply the servo drive with power. On JOG mode, position the axis at a proper position.
3. Enable REF (return to reference point) mode.
Here, on NC screen, display START UP screen to show AXIS MD (machine data of
axis) so that you can check the setting values with MD34210 : ENC_REEP_STATE
(origin setting status) for the both of master and slave axes.
Specify "1" for the setting value with MD34210 : ENC_REEP_STATE (origin setting
status) of the both of master and slave axes in order to enable the origin setting function
mode.
When you want to position the axis at a certain coordinate position, follow the proce-
dure for the setting of step 4 and then step 5. Otherwise, go on to step 5.
4. Input the coordinate value to specify with MD34100 [0] : REEP_SET_POS (coordinate
value after origin setting) for the master and slave axes.
5. Set the axis feed (key) for the direction specified with MD34010 :
REEP_CAM_DIR_IS_MINUS (return to reference point direction); "0" for the positive
direction and "1" for the negative direction. (However, the axes does not move actually.)
6. When step 5 has completed, there automatically displays "2" for the status value of the
master and slave axes with MD34210 : ENC_REEP_STATE.
When a certain coordinate value is specified on step 3, the origin setting process has
completed when NC screen (coordinate value display: MCS) displays the value equal to
the value with MD34090 : REEP_MOVE_DIST_CORR.
7. Check the gantry axis for synchronized motion. The process is completed.
