Import Drive Parameters in ServoDesigner
The final stage of drive parameter configuration involves loading the drive parameter settings into a ServoDesigner
database and writing the registers to the IRMCK203. For information about how to use ServoDesigner, refer to the
ServoDesigner User’s Guide. In particular, Section 10.3 of that document describes the Import Drive Parameters
feature.
The text file exported from the Excel workbook contains two sections: Parameters and Registers.
The Parameters Section
The Parameters section specifies motor configuration parameters, which are saved in the ServoDesigner configuration
file (.irc file). In ServoDesigner, the settings can be viewed and modified by selecting Motor Configuration from the
Preferences menu. When the drive parameters text file is imported into ServoDesigner, the motor configuration
parameters in the import text file always replace the current settings in the ServoDesigner database.
The Registers Section
Each of the entries in the Register section of the file identifies a write register and a value to be stored in the register.
In a ServoDesigner database, there are several locations where each register value can be used:
• In the register definition, the Value to Write is written to the corresponding IRMCK203 register when the
register entry is double clicked.
• Also in the register definition, the EEPROM Value to Write can be saved to EEPROM and used to initialize
the IRMCK203 register on power up.
• In the Function Definitions section, one or more functions may write the register value to the IRMCK203.
(A function is set up to perform a sequence of operations automatically.)
When the drive parameters text file is imported into ServoDesigner, there are several options for updating any or all of
these register settings with the value specified in the file.
Step 1. Run ServoDesigner and Open a Database
Start ServoDesigner and select Open from the File menu. ServoDesigner configuration files have the file extension
“.irc”. Browse to locate a ServoDesigner configuration file and open it. (To create a custom configuration file to use
with a specific project, it’s best to make a copy of the example file included with the release.)
