Z Axis Stage Behind the Limits
NOTE: This condition usually occurs when the
machine goes into the lube cycle and the cycle
is interrupted before it has completed its run.
SYMPTOM: When the machine is powered-up
and the “Check” icon is pressed, the Z axis tries
to go to its home position by moving in the –Z
direction. Under normal conditions the axis
moves back until it trips the sensor and then
steps forward into the home position. When the
stage is already behind the sensor it will con-
tinue to follow the same program. It will now
move all the way back and eventually into a
hard stop and sit there with the motor stalled.
Usually there is a squealing noise and the X axis
error will usually appear. To verify this is the
problem measure the front of the chuck Jaws to
the face to MT01. With the chuck in the sharp-
ening position, the distance between the 2
should be no more than 1” . The procedure to
recover from this is as follows:
1. Remove drill from chuck
2. Open the chuck all the way
3. On the initialization screen, touch the screen
just to the left of the D in “DAREX”
4. Press
icon located at the end of
the third row on the maintenance screen.
Immediately, the Z axis stage will move in the
+ direction about 1 inch.
5. Power off the machine, wait 5 seconds then
power it back on.
6. Press the “Check” icon, another limit error
may appear. Press :“Ok” and the machine will
initialize and move into the home position.
If the above procedure does not correct the
Problem repeat steps 3-6.
IMPORTANT: The stage will not stop until it has
moved the entire 1” regardless of what is in its
path. If you see interference between the chuck
and any other part of the unit, press the E-Stop
button right away.
If the above procedure does not correct the
problem, contact Darex. 800-547-0222.
