6.6.3 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.

6.6.3.1 Check the dynamic Star axis

Please Note:

For check the dynamic please use the official Adjustment manual.

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.
