7.4 Gantry Axis Control
7.4.1 Track Signals and Zero Pulse
Track signals and zero pulse signals should be produced reliably by correct mechanical installation.
Should errors or malfunctions occur, check the machine as usual.
Previous incremental encoders show track A/B count signal amplitudes of 1.8 to 2.5 Vss.
New incremental encoders with 1 field optical systems have count signal amplitudes of 1.8 to 3.6 Vss.
7.4.2 Checking the X-Axis Dynamics
7.4.2.1 Overview
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 (trigger for position deviation)
NOTE:
For further details, refer to the service manual for the respective machine.
NOTE:
For detailed information about checking the dynamics, refer to the settings instructions.
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.

7.4.2.2 Measurement Setup with Adapter Board for A364
7-10: Measurement setup with axis test box
Additional connection at channel 4 could be the actual position = target position signal from trigger
m1/2 of the adapter board or the position deviation.
NOTE:
Measure the signals directly at the adapter board!
The position deviation issued there offers the benefit of showing the axis controller state.
ATTENTION:
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 dynamic
analysis.
