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: Transmitted 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:

To check the axis dynamic, please use the "Adjustment manua HF platform".

– An additional connector on channel 4 is the actual pos.=nom.pos. signal from the axis testbox.
