Test Motion Parameters - MachMotion Apollo III Manual

P a g e | 59
By selecting the AutoReverse check box, the system can make the axis reverse direction automatically for the
next motion command and thus avoid the axis continuing on in one direction during testing. The Ready LED shows
if the Apollo III is ready to accept a motion command. If the Ready LED is green, it implies that the controller is
ready to accept new motion commands. While executing a motion profile, the Ready LED turns to red and
Apollo III cannot accept a new motion command until the current motion sequence is completed or cancelled.
Once the test motion command has completed, the accuracy of the commanded motion profile can be seen on the
on the Motor/Drive Response graph. The acceleration and velocity can be optimized to get the machine's
following error to a minimum.
FIGURE 70 MOTOR/DRIVE RESPONSE GRAPH
The blue line represents the actual position, the red line shows the commanded position, and the green line
displays the actual speed. Therefore the distance between the blue line and the red line is the following error.
Below is a review of all the test motion parameters. Read this section for more information.

10.3.1 Test Motion Parameters

Position – Test motion final position or displacement in terms of Position Units, e.g. 1.5, 10.093, mm or inches etc.
Acceleration – Test motion acceleration value in terms of Units per second squared, e.g. inches/second , mm/sec etc.
2 2
Velocity – Test motion velocity value in terms of Units per minute, e.g. inches/minute, mm/minute etc.
Relative and Absolute – These check boxes indicate whether the value in the Position field is the distance to travel (relative) or the
final position (absolute).
Execute Button – Transmits Execute Motion command to Apollo III. In addition, it also downloads control parameters before
starting the motion. User can press the CANCEL button to cancel the motion execution anytime during the machine operation.
Make sure that the axis control settings have been downloaded by clicking UPDATE HICON before clicking on EXECUTE. Motion
commands can be run by pressing the EXECUTE button when the Ready LED is green.
DRIVE ON Button – By clicking this button, the plugin downloads the parameters and enables the drives. If DRIVE ON is active, the
LED below this button will turn to green. Otherwise it will be red.
