Å Start SITEST.
Å Turn on the compressed air.
Å Prepare the measurement setup for the star - axis according to fig 7.4 - 4.
Å Set the oscilloscope according to the table below.
Å Perform a head reference run.
NOTE
Use an RC - filter to record the current curve
Measure the end signal on the adapter board "axis control card", (the lowest BNC socket), with
the switch activated.
Measure the nominal current of the star - axis on the "measuring adapter axis control card current
measure star" (Do not connect GND).

NOTE
An adjustment of the star - axis on the servo amplifier is not possible.
Adjustment parameters are preset by board VC10 Controller. This board is on the axis control card
1, or 2, 3 or 4.

– If the dynamics of the star are correct, each signal will appear as illustrated above.
–Nominal - positioning time:PVPV.
1 cycle = 12000 dgts = 30°degrees.
NOTE
If this setting for the dynamics can not be reached, check the friction blocks on the star and the
mounting of the star while the drive is in its magnetic park position.

Å Start SITEST.
Å Turn on the compressed air supply.
Å Prepare the measurement setup for the star-axis acoording to fig 7.4 - 4.
Å Use standard nozzle 914.
Å Set the oscilloscope according to the table below.
Å 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.
