(17) Display the number of pulses in this position using the PULSE command and check
that they match the values obtained in step (12) on previous page.
<Example>
>
PULSE
16000 10000
' Axes #1 and #2 pulses.
0 -10
' Axes #3 and #4 pulses.
(18) Use the SLOCK command to put the free axes back under servo control.
<Example>
>
SLOCK 1,3
' Axis #1 and #3 are under servo control.
(19) Move to another teach point and check the position.
Accurate calibration of Axis #2
For accurate calibration of Axis #2, calculation of robot working point coordinates is most
important in the following cases.
Entering coordinate values to teach a point.
Switching the arm orientation between right and left at a given point.
Using the PALET command.
During CP control (such as liner or circular interpolation).
Using the LOCAL command.
For statements using relative coordinates. < Example,
P1+X100
>
If the methods above require accuracy of Axis #2, then calibrate for both right and left arm
orientations. Note that this method cannot be used if Axis #4 has excessive run-out.
(1) Display HOFS values using the HOFS command and note values [A], [B], [C], and
[D].
<Example>
> HOFS
[A] [B]
' HOFS values for Axes #1 and #2.
[C] [D]
' HOFS values for Axes #3 and #4.
(2) Select a point for teaching that is within the region accessible to both right and left arm
and is easy to verify for accuracy. Carry out teaching and call the point P1.
<Example>
>
P1=P*
(3) Display the number of pulses at the P1 position using the PULSE command. Note the
Axis #2 value
[F1]
.
<Example>
> PULSE
[E] [F1]
' Axes #1 and #2 pulses.
[G] [H]
' Axes #3 and #4 pulses.
