Variables
The Variables menu may be used to set the values of the nonvolatile variables G1 through G64. If values
are changed in the program while this dialog box is open the new value will not be displayed. The value
is updated whenever you open the dialog box or change from one G variable to another G variable. To
continuously monitor the value of a variable continuously, refer to the Monitor menu, Monitor Variables
on page 69.
To set a variable, select Variables from the Parameter menu, then select the variable you want to change
from the drop down list box. TAB to the Value box and enter the new value in the Value box. If not
using a mouse, press ALT+DOWN ARROW to open the drop down box. Once the box is opened, use
the UP and DOWN ARROWS to scroll through the selections. As a variable is highlighted, the value of
the variable will be shown in the Value box. To make a selection, press the ALT+UP ARROW or
ALT+DOWN ARROW to select the highlighted item.
Choose Cancel to leave the dialog box without saving any changes. After changing a variable value,
choose OK to store the new value and close the dialog box. Choose Update to store the new value, but
still leave the Variables dialog box displayed
Edit Parameter File
New
Select New from the Edit Parameter File menu item under the Parameter menu to create a new Parame-
ter hex file on the PC. The file will contain default values for the parameters independent of motor size.
Once the file has been opened, you may print or edit the file just like any other text file. However, when
the file is saved, it will be converted back to a Parameter hex file--not a text file. Only minimum range
checking is performed on the parameters (because there is no personality module data to compare
against) so use caution when editing the file. Do NOT edit the parameter labels on the left side of the
equal sign – only edit the values on the right side of the equal sign. If any parameters are missing (or IQ
Master is unable to recognize a parameter label) when the file is saved, the save will be aborted. In other
words, the file must contain a full list of parameters before it will be saved to disk.
Open
Select Open from the Edit Parameter File menu item under the Parameter menu to open an existing
Parameter hex file on the PC. Select the file to be opened from the Open file dialog box. The file to be
opened must be a valid Parameter hex file that was transferred from an ULTRA Plus or IQ or created
with the Edit Parameter File, New menu item.
Once the file has been opened, you may print or edit the file just like any other text file. However, when
the file is saved, it will be converted back to a Parameter hex file--not a text file. Only minimum range
checking is performed on the parameters (because there is no personality module data to compare
against) so use caution when editing the file. Do NOT edit the parameter labels on the left side of the
equal sign – only edit the values on the right side of the equal sign. If any parameters are missing (or IQ
Master is unable to recognize a parameter label) when the file is saved, the save will be aborted. In other
words, the file must contain a full list of parameters before it will be saved to disk.
ATTENTION
!
Modifying variables while a program is running may result in
unexpected machine motion. It is also possible that the program will
overwrite a variable after the user modifies it. It is the responsibility of
the user to determine the potential hazards involved. Failure to
observe these precautions could result in bodily injury.
