Analog Track Signals
6.4.2.1 Analog Track Signals
To check the track signals, connect the track signal tester and the oscilloscope. (see "6.4.1.1 Measuring
the Analog Zero Pulse Signal" [ ➙ 197])
► Switch the machine on.
► Switch the track signal tester to Calibrate oscilloscope.
► Switch the oscilloscope to DC, Refr., Non Store, Auto (20 ms).
► Voltages V/Division decrease up to 0.5 V/Div.
► Switch the oscilloscope to X/Y --> Illuminated point will appear!
► Move the point into the middle of the display.
► Measurement system to position Sinus amplifier output.
► Manually move the selected axis back and forth.

6.5.2 Checking the X Axis Dynamics
The inspection of dynamics occurs with the following signals:
▪ Deviation of position
▪ Uncommutated target current value
▪ End signal (adapter board, axis in target position)
▪ Actual position = target position signal (axis test box output end position signal)
"Axis control" assemblies
The control loop for the X and Y axis consists of the
following parts:
▪ Axis card A363 with VC3 controller or A364
▪ Servo board (TDS)
▪ 3 phase AC linear motor
▪ Measurement system (incremental scale and
encoder (read unit))
To protect the linear motors from overtemperature, all
these motors have an internal temperature sensor.

GREEN: power supply ON
GREEN: Servo enable, if the enable signal has been
received from the axis board.
ORANGE: Display R.M.S. current limiter shorter than
2.5 s.
RED: Error: overvoltage, overcurrent,
overtemperature longer than 2.5 sec.
5. 3-phase AC linear motor for X and Y axes with
integrated temperature sensor.
6. Between the motor and incremental encoder there is
a fixed mechanical connection.
7. Incremental encoder: transmits the exact position of
the axis. The track signals are the only feedback
signals for the axis control.
The servo board directly controls the linear motor, the
intermediate circuit voltage is 250 V.
NOTICE
Before checking the axis dynamics, make sure that the machine has reached its operating
temperature. Switch the machine on at least 30 minutes before you begin work.
