6.3.3 Axis control Star axis
The Star axis is driven with a 3 phase AC stepping motor with an intermediate circuit voltage of
120V. The control of the axis occurred with two control signals of the VC3 (dephasing 120°) con-
troller I
nom "W" and I nom "U". The third phase is calculated automatically.

6.3.3.1 Check the dynamic Star axis
Please Note:
For detailed notes to check the axis dynamic, please use the "Adjustment manual".
Please Note:
Before adjusting the axes, ensure that the machine has reached its operating temperature.
Switch the machine on at least 30 minutes before you begin work.
Axis card A363 with VC 3 Controller (VC = Velocity Commutation)
Control signals I
nom "W" and I nom "U"
LED‘s on the Servo amplifier:
– Power supply ON
– Servo enable, if the the enable signal from the axis board available.
– Display R.M.S. current limiter shorter than 2,5 s.
– Error: Overvoltage, -current, -temperature or Nominal current-overstep-
ping longer than 2,5 sec.
Servo board control directly the 3 phase AC motor.
3 Phasen AC Motor.
Between the motor and the incremental encoder exist a fixed mechanical
combination.
Incremental encoder: transmit the exact position of the axis via the track
signals.

6.3.3.3 Test setup with SAT-Box
Please Note:
-> for dynamic check it may be enough to check positioning time and overshoots of the
axis with the display at SIPLACE Axis Tester and the values from adjustment tables.
-> for troubleshoting the dynamic analysis have to be done with a appropriate oscilloscope
->For further hints checking the dynamics with the aid of the SAT-Box please use the official Ad-
justment manual. 6
