➠ Start SITEST.
➠ Turn on the compressed air supply.
➠ Prepare the measurement setup for the star-axis acoording to .
➠ Set the oscilloscope according to the table below.
➠ Perform a head reference run.
NOTE
Use an RC - filter to record the current curve
In order to measure the actual current on the servo amplifier, connect only the actual current and
no *1'.
Measure the end signal on the measuring adapter of the axis control card, with the switch
activated.

NOTE
If the P-gain is set too low, the deviation of position will sag and the end signal will be prolonged.
If the actual current is set too high, the end signal will be prolonged as well, the actual current and
the deviation of position will oscillate however.

➠ Select "C&P Heads" ==> "Select head ==>
"Axis functions" ==> "Select dp - axis" ==> "Tacho adjustment".
➠ Use the potentiometer "Tacho" on the servo board to adjust the displayed value on the station
monitor to 0V +/- 10 mV.
