6.4.2 Checking the X Axis Dynamics
Checking the X Axis Dynamics
The inspection of dynamics occurs with the following signals:
▪ Deviation of position
▪ Uncommutated target current value
▪ Vnom. – speed signal
▪ End signal (adapter board, axis in target position)
▪ Actual position = target position signal (upstream end position signal)
"Axis control" assemblies
The control loop for the X and Y axis consists of the fol-
lowing parts:
▪ Axis board A364
▪ Servo board (TDS)
▪ 3 phase AC linear motor
▪ Measurement system (incremental scale and encod-
er (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, overtempera-
ture longer than 2.5 sec.
5. 3-phase AC linear motor for X and Y axes with inte-
grated 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 sig-
nals for the axis control.
The servo board directly controls the linear motor, the in-
termediate circuit voltage is 250 V.
NOTICE
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.

NOTICE
Measure the signals directly on the adapter board!
The position deviation emitted there offers the advantage of showing the actual axis controller
function.
CAUTION
When checking the dynamics, it may be sufficient if you check the travel times and overshoot
behavior of the axis with the SIPLACE axis tester (SAT) display and the values in the settings
tables.
However, when checking for errors, you will need to use a suitable oscilloscope for the dynam-
ics analysis.
