20.3 ’SAT’ Machine Testing Menus

20.3.1 Exit

This menu saves the current settings and deactivates the system.

If the SIPLACE Axis Tester ’SAT’ is just unplugged, current settings won’t be saved for rebooting

but other problems will not occur.

If the ’SAT’ is disconnected from one axis controller and plugged into another, the SAT program

will remember the menu last used for a short time and will display it again after rebooting. To dis-

play the main menu, simply hit one of the keys!

20.3.2 Testing Track Signals

20.3.2.1 Displaying the Track Signals at the Axis Controller Input

This can be manually performed over the whole traversing range with the track signal tester for

the incremental encoder analog output signals. Representation of the digital track signals, to-

gether with manual axis displacement for fault analysis purposes, is not optimal, as it is difficult to

differentiate between slow displacement and track signal failure. However, the ’SAT’ can be re-

configured so that track signals can be tested at the axis controller input. This method shows the

BNC outputs with LNA ’Line A’ for track A or LNB for track B; a zero pulse index for the relevant

axis and, synchronously, the end signal (ENDE) at BNC 4.

The track sig-

nals can be

shown by:

- manual axis

displacement

(oscilloscope

set to trigger

mode ’Auto’)

- with an axis

positioning and

trigger signal at

the end signal

or zero pulse.

20.3.2.2 Testing Track Signals/Zero Pulse after a Gantry Axis Reference Run

As well as displaying track signals at the axis controller input, counting pulses can be tested along

the entire traversing range of the linear scale (even without oscilloscope representation).

Connect the SIPLACE Axis Tester SAT to the

respective Axis controller board

Boot the SAT and press ' ' to activate main menu

Select 'configuration'

Select 'Panel'

choose the desired 'Signals'

Selection 1 for Positioning quality/ Selection 2 for

Track signals/Selection 3 for actual pos.=nom.pos.-

End signal comparison/Selection 4 internal Signals

with Cursor up/down and confirm

with 'return' <-

Select menu 'Activate Panel'

Back to the menu 'Positioning quality'

Here you get the position deviation signal

to the SAT screen incl. time analysis.

The menu 'Back' returns back to

the previous menu level

This switches the signal to the SAT BNC-

output connectors

Default Signal combinations:

Selection 1Vnom/Vreg/ISoll/End

Selection 2 LNA/LNB/Index/End

Selection 3 LNA/LNB/Trigger/End

Appendix

The ’line fault’ menu can

be used to test the count-

ing pulses and traversing

time between the re-

peated zero pulse win-

dows. Zero pulses de-

tected as

counting errors

will be "

underlined’. Zero

pulses read as

time er-

rors

will receive an ’over-

line

’.

The first zero pulse always

has an overline and under-

line, as might the last one,

if it has been passed sev-

eral times due to multiple

overshoots. Therefore,

before beginning mea-

surement, teach the gan-

try axis so that it is placed

next to the 0 pulse (see

oscillogram Fig. 20.3 - 3.)

This menu is not designed

for use with head axes.

Fig. 20.3 - 2 Sequence of steps for line errors

Alternatively to the manuell movement of the axis and the automatic scrolling back for the mea-

surement you can also run a continous run for a Tracksignal check between the zero pulses. The-

refore run a positioning over the full travel range with more then 2 seconds waiting time at each

position. So you are able to ’start for reference’ at one position and arriving at the other position

the measurement is stopped and the result is displayed.
