123 shows the Packed Bits Control Words view onto which the user has dragged several motion initiate parameters.
Figure 123:
Enable Packed Bits Control and Status Words
In order to use the Pack Bits Control Word and Status Word mapping, the function must be enabled by activating the Enable Packed
Bits Control and Status Words check box. If the check box is clear, the view remains blank (default). If the check box is selected,
then the mapping tree appears which allows the user to configure the Control Word(s) as desired. This check box enables both
Control Words and Status Words, and the two cannot be enabled/disabled independently.
Number of Control Words
The user can specify the number of desired 16-bit Control Words for the application. This parameter is adjustable from 1 to 4 words
(1 default) using the arrows next to the box. The Number of Control Words cannot be adjusted while online with the device. If online,
the user must disconnect communications and then adjust the number of control words.
Control Word Setup Tab
The Control Word Setup Tab is used to map the desired bit-level parameters onto the existing control word(s). The parameters can
be mapped using one of two methods:
Drag and Drop: Using the Drag and Drop method, the user navigates the parameter tree, which as been pre-filtered to only show bit-
level parameters, to find the desired parameter they wish to control (write to). Once the desired parameter is found, the user left-
clicks and hold on the desired parameter. While still holding the left-button down, the user drags the parameter onto the desired bit of
the desired Control Word. Then the left-button is released. Doing so will map the selected bit parameter to the selected Control Word
bit.
Add Button: Using the Add Button method, the user navigates the parameter tree to find the desired parameter they wish to control.
Once the desired parameter is found, the user left clicks on the parameter to highlight it. Then the user clicks on the desired bit of the
Control Word to highlight it. Once both are highlighted, the Add button on the right side of the view (see Figure 123 above) should
become available. Simply click the Add button and the highlighted parameter will be assigned to the highlighted bit on the Control
Word.
To delete parameters from the Control Word, simply drag and drop the parameter off the control word (see explanation above), or
highlight the desired parameter to delete, and click the Delete button on the right side of the view.
NOTE
Parameters can be mapped while online, but cannot be sent to the drive using the Update to RAM function. Therefore, any changes
to Control Word mapping requires a full download.
Online Status Tab (Available Online Only)
While online with the drive, the user can monitor the Control Words value (see Figure 124). The data is displayed in binary form for
each individual bit of the Control Word(s), as well as hexidecimal and decimal format for each Control Word.
