➠ Start SITEST.
➠ Make sure that all friction surfaces are clean.
➠ Prepare the measurement setup for the y-axis. (See Fig. 8.9 - 3).
➠ Perform a head reference run.
➠ Perform a gantry reference run.
NOTE
Use an RC - filter to record the current curve
Measure the end signal on the adapter board "axis test box", with the switch pressed down.

NOTE
Adjustments of the gantry axes on the servo amplifier are not possible.
Adjustment parameters are preset through board VC10.
This board is positioned on the axis control cards 1, 2, 3 and 4.
Measure the nominal current of the y-axis at the "measuring adapter axis control card, measuring
pin, axis 1".
(Do not connect GND).

➠ Select "Gantry" ==> ==> "Select gantry" ==>
"Axis functions" ==> "Select y-axis" ==> "Adjust P-gain" ==>
"Select travel range with the help of the ÇÆ arrow buttons".
– If you adjusted the dynamics of the y-axis correctly, each individual signal will be
displayed as shown in Fig. 8.9 - 4
and Fig. 8.9 - 5.
➠ To end the procedure, select "Abort".
