5.2.5.2 TwinHead Axis Track Signals
TwinHead Axis Track Signals
The track signals play a greater role with the new drive concept for HF machines. They are responsible
for the exactly and precise positioning of the axes and are used as the only feedback signal in the closed-
loop control system, meaning that they have an important influence on the axis dynamics.
Measurement Setup
Measurement setup for the analog track signals of the Twin head Z axis
The analog track signals of the TwinHead Z axes are counted by the incremental encoder.
NOTICE
Measurement only with Axis Test Box
The digital track signals for the TwinHead can only be measured at the Axis Test Box. The track
signals for the TwinHead D axis can only be measured as digital signals at the Axis Test Box.

NOTICE
Inverted zero pulse
The zero pulse measured at the axis test box has been reversed to become the zero pulse of
the Schmitt trigger circuit.

5.2.5.3 Axis Control of TwinHead Z Axis
Axis Control of TwinHead Z Axis
The Z axis is driven by a 3-phase AC linear motor. The intermediate circuit voltage is 60 V (for high force
TwinHead 120 V). Axis control is via two control signals from the VC3 controller (phase shift 120°) I nom
"W" and I nom "U". The third phase is generated at the servo amplifier.
Checking the TwinHead Z Axis Dynamics
Axis control of TwinHead Z axis
1. Axis controller board A363 with VC3 controller (VC =
Velocity Commutation)
2. Control signals
3. Servo amplifier
4. LEDs on servo amplifier:
5. 3-phase AC linear motor with integrated temperature
sensor.
6. Between the motor and the incremental scale there is
a fixed mechanical connection. The incremental en-
coder is fixed to the TwinHead housing.
7. Read unit: transmits the exact position of the axis
(track signals).
8. Force sensor
The servo board controls the 3-phase AC motor directly.
CAUTION
Switch machine on 30 mins before start
Before adjusting the axes, make sure that the machine has reached its operating temperature.
Switch the machine on at least 30 minutes before you begin work.
