Export Drive Parameters in Excel
In the second stage of configuring drive parameters, the parameter settings selected in the previous section are used to
calculate values for a number of IRMCK203 write registers. The write register values are written to a text file in a
specific format defined for use with ServoDesigner.
Step 1. Note Shunt Resistor Value
At the bottom of the “User Entries” worksheet, note the calculated current feedback shunt resistor value shown in
column F (see Figure 10). If the value shown does not correspond to an available resistor, it may be necessary to
modify the “Drive peak amps” setting. After modifying the value, check the shunt resistor value again.

Step 2. Save the Settings
When all parameters are set appropriately, select Save from Excel’s File menu to save the workbook file in “.xls”
format.
Step 3. Export Drive Parameters
Click on the Parameter Export tab at the bottom of the workbook window. This worksheet shows the register values
that were calculated settings were changed in the motor setup worksheet. From Excel’s File menu, select “Save
As…”. In the Save As dialog, select Save as type: “Text (Tab delimited) (*.txt)” as shown below. Then browse to
the folder where the exported drive parameters file is to be saved, specify a file name, and click Save.
