Introduction
This Guide give basic instructions on the functionality and implementation of the MotionCore.DLL API. Only
experience developers of motion control software should attempt to use this API. A working knowledge of the
Parker/Acroloop AcroBasic language is also required to full implement a finished motion system.
Operating System
This 32 bit DLL is for use in MS Windows NT 4.0 (service pack 4.0 or above) , 2000 or XP Pro
Installation
Parker-Hannifin API Installation will prompt you to create a folder…C:\Program Files\Parker\ACR-
MotionMax. All references in this document will assume the users accepted the default folder.
When the Installation is complete, a prompt to reboot the computer will be displayed. In order for all of the
drivers to be properly activated, the computer must be rebooted before any calls to the MotionCore.DLL can be
placed.
Installation Folders and Files
The Installation will generate the Axium Folder and several sub-folders.
Docs – this folder contains this document and others
ParFiles – this folder cantains all of the storage files incuding the configuration files
Samples – this folder contains a Visual C++ and a Visual Basic sample.
The MotionCore.DLL file was installed in the Windows\System32 folder. This is done so it is accessible from
anywhere on the computer. Since the System32 folder is found in the Windows path, you do need to reference
any drive and folder information to locate it.
The ACR-MOTIONMAX.INI files is alos located in the Windows folder. This file contains the location of any
files you create as well as the file location of the configuration files. This file can be edited with any text editor
and cahnged to accommodate you specific application. The files looks like the following…
[PATHS]
Root=C:\Program Files\Parker\ACR-MotionMax
Config=C:\Program Files\ Parker\ACR-MotionMax\ParFiles

These bits [128-255] used by the DLL for communication with the VB and AcroBasic.
The MotionCore.DLL depends on these bits so don’t use them in your Vb programs for any other purpose than
as defined below. If you need to use some bits for your program logic, we have set aside some User Scratch Pad
bits at bit locations (224-248) that you may use as desired.
