Now the referencing direction of the axis has to be adjusted.
Make sure the axis is not in
a limit switch position.
To do this you have to go to the adjusting field “referencing”.
The hardware limit switches of each axis are fixed and should not be changed by means of
the configuration program. Please take a look at the window for the inputs and outputs.
Entry no. 5 and 6 is:
Both limit switches are plugged in correctly if the left LED next to the entry is blue
in inactive condition.
3) Move the Z-axis by pushing
Alt + Ctrl + page up slowly
up in the direction of the
limit
switch. +
. While moving, watch the display of the inputs, in particular
input no. 6 limit
switch Z+
.
Now
move
until
the
blue LED
for
limit switch Z+ goes out
.
Should this not be the case and the LED for limit switch Z- goes out instead, you have to
exchange the wiring of the signal cables for the limit switches on the circuit board. This
means you have to exchange limit switch Z- and Z+ for the Z axis.
As soon as the LED for limit switch Z+ is out, please move to the opposite direction away
from the limit switch. Now the LED has to be blue again.
Repeat
this step
again for the
other limit switch
. Move the axis by pushing
Alt + Ctrl +
page down.
Also check the functioning of the limit switch.
4) After you have checked both hardware limit switches, you have to adjust the referencing
direction. For this purpose you have to move the axis to the middle of the traverse range.
Click on “Test“ all the way on the right within the entry field of the according axis. Watch
the movement of the axis. If the axis moves
up in direction of limit switch Z+
, the
referencing direction is adjusted correctly
. Now you have to check the reference input,
that is to be used for
referencing
. In this case
input no. 6 limit switch Z+
serves as
reference switch
. (see picture above)
If the axis does not move in the right direction, please cancel the referencing of axis by
pushing F9 or the button
. Now invert the referencing direction by pushing the
button
. Save the adjustments.
Repeat the referencing to check the adjustments again.
5) If the referencing was successfully completed, save all adjustments. Activate the hardware
limit switch monitoring for the axis within the entry field I/O-activities by checking the
first check box. (see also chapter: 3.5.2.5 I/O- Actions). Save the adjustments again.
