5.4.2.2 Digital Track signals
To check the track signals use the same test setup which is descriped under point 5.4.1.2 .
The measurement procedure is the same as descriped under point 5.4.2.1 .

5.5 Axis control
5.5.1 Parts for the axis control
The control loop for control the X- and Y-axis in general consist of the following parts:
– Axis board with VC 3 Controller
– Servo board (TDS)
– 3 Phase AC linear motor
– Measurement system (Incremental scale and encoder)
All linear motors have temperature sensor to protect it against high temperature.
Fig. 5.5 - 1 Parts "Axis control"
Axis board A363 with VC 3 Controller (VC = Velocity Commutation)
Control signals I
soll "W" and I soll "U"
Servo board control directly the linear motor, Intermediate (DC) voltage cir-
cuit is 250V.
LED‘s on Servo board:
– Power supply ON
– Servo enable, it the enable signal from the axis board.
–Display I
RMS limit shorter than 2,5 s.
– Error: Over voltage, -current, -temperature longer than 2,5 sec.
3 Phase AC linear motor X-and Y-axis with integreted temperatur sensor.
Between motor and incremental encoder exist a fixed mechanically connec-
tion.
Incremental encoder: Transmitte the correct position to the axis board and
is the only feedback signal to control the motor (Track signals).

5.5.2 Check dynamic X-axis
The inspection of dynamics occurs with the following signals:
– Deviation of position
– Nominal current
– End signal ( Adapter board Axis in target position)
– Actual position = nominal position ( Axis testbox Output end signal)
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.
