Changing PowerFlex 750-
Series Drive Parameter
Associations PowerFlex 750-Series drives have special parameters (indirect selector parameters
and reference parameters) which are always associated with other parameters.
The values for these special parameters are actually pointers to other parameters
in the drive or to
Host
parameters in connected peripherals. To change a
parameter association, first access the indirect selector or reference parameter.
Second, select the port number of the device whose parameter you want to target
for association. Then, select the target parameter of that device. If the target
parameter is a bit parameter, you must also select the appropriate bit you want to
associate with the indirect selector or reference parameter.
Parameter associations can be changed using one of these methods:
• Individual Screen Entry Method—where individual popup screens are
used to enter the required parameter association data.
• Direct Numeric Entry Method—where the required parameter association
data is entered as a number string on a single popup screen.
The following example illustrates how to use each method to change a parameter
association. Suppose you want the drive speed reference to come from the
network controller via the embedded EtherNet/IP adapter on the Main Control
Board in a PowerFlex 755 drive.
Using Individual Screen Entry Method
1. Access the indirect selector or reference parameter whose association you
want to change (for this example, drive Parameter 545 - [Spd Ref A Sel] as
shown below).
In this example, the Port field is shown selected. Use the or
key to select the Port, Parameter, or Bit (if applicable) fields.
TIP
Depending on the indirect selector or reference parameter selected,
you may see more available ports in the list.
