CHAPTER 3 Installation
(4) After the Z-axis absolute reset is complete, press the F10 (UPPER+F5) key
to display the adjustment machine reference value (%).
When the machine reference is within the allowable range (between 26%
and 74%), proceed to step 16). If the machine reference is outside the al-
lowable range, adjust it as described in step 11) onward.
11) Turn off the controller and enter the safeguard enclosure.
12) Put a mark at the added stopper position and loosen the bolt for the added
stopper.
To adjust the machine reference value, move the added stopper as follows:
Machine reference value < 26% : Move the added stopper in the plus direc-
tion.
Machine reference value > 74% : Move the added stopper in the minus direc-
tion.
As an approximate guide, a 3mm movement equals 100%.
13) Repeat the same procedure from step 6) until the machine reference is
within the allowable range.
14) When the machine reference is set within the allowable range, go out of the
safeguard enclosure.
15) Check that no one is inside the safeguard enclosure and then turn on the
controller.
16) Set the soft limits as shown in Table 3-6.
The soft limit in the minus direction is already set by default to the value
shown in Table 3-6.
17) Stay outside the safeguard enclosure and check that the soft limits work to
stop the Z-axis unit at a point before the stopper position. Depending on
the accuracy and position of the stopper parts, the Z-axis unit may not stop
until it reaches the stopper. In this case, set the soft limits larger than the
values shown in Table 3-6.
18) Check that the movement range is limited by the stoppers as desired.
19) Turn off the controller and enter the safeguard enclosure.
20) Reattach the Y-axis arm cover.
