– If the dynamics of the star are correct, each signal will appear as illustrated above.
–Nominal - positioning time:PVPV.
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.
