4.1.5 Finding Best Acceleration
Especially for odd shape components, but also for standard components, users often reduce the
acceleration of the axis to a low value just to ensure that the board is placed correctly and no com-
ponents are lost. However, by doing so the current acceleration is usually below the optimum.
A new teaching function supports finding the optimal acceleration or speed values for a component
shape directly on the station. The dialog for teaching component shapes has been enhanced by
the new Teach acceleration values function.
The selected component is picked up with the selected nozzle and moved around within the
machine with increasing acceleration values for each axis. Based on the Vision measurement, the
optimal acceleration is determined. The value can be tested again and uploaded to SIPLACE Pro
afterwards.
Prerequisites
●
Activity level: Machine service
4.1.5.1 Procedure
The following overview lists the single work steps that have to be performed in the specified order
to find the best acceleration.
Finding best acceleration
Step Action SIPLACE program
1) Enabling OSC package SIPLACE Pro
2) Selecting the component from the list in the dialog for teaching
component shapes and starting the Teaching acceleration val-
ues function
Station Software
3) If necessary, changing the configuration (other nozzle, disabling
automatic removal of components)
Station Software
4) Starting the execution Station Software
5) Checking the result Station Software
6) Testing the recommended acceleration Station Software
7) Uploading the acceleration values to SIPLACE Pro Station Software
4.1.5.2 Application Example
Step 1: SIPLACE Pro
► In the Station Editor under Placement Station,
enable the OSC Package option under Installed
options.

Step 2: Station software
► Switch to the Machine service activity level.
► In the dialog for teaching component shapes,
select the component from the list.
► Click on Teach acceleration values.
The Configuration teach dialog is displayed.
The following decisions can be made in this dialog:
●
Used nozzle
If you want to perform the teaching with another nozzle, the nozzle can be selected from a list.
Only available nozzles will be displayed.
●
Option for disabling the rejection of components
The default value is set to reject the components automatically. But if the Components must
be removed manually option is set, you will be prompted to remove the component manually
from the placement head as soon as the check fails. The option is only available for place-
ment heads for which components can be removed manually (please refer to the Online Help
of the station software). Once set, the value is saved for the next run.
Step 3: Station software
► If necessary, select a nozzle from the list for the
teaching.
► If necessary, enable the Components must be
removed manually option.
► Click on Start.
The function is performed automatically for the X-/Y-, star und DP axes. The Execution teach dia-
log is displayed.

Step 4: Station software
The execution steps are displayed together with the reference Vision image and the last Vision
image done by the camera. Additionally, the current acceleration values of the axes and the
measured deviations are displayed. If you have to remove a component from the placement head
manually or if the component is lost, a hint will be displayed and you must confirm the action to
continue.
If an error occurs during execution, the error causes are displayed on the last page in an error list.
Otherwise, the results are displayed in the Results dialog.
Step 5: Station software
► Check the results. The recommended values can
be compared with the values of the programming
system.
► Click on Test recommended acceleration values
to test the values.
The teach dialog is closed and the Configuration test dialog is opened.
