SECTION 2.6

Using the IMS SPI Motor Interface

Installation

The IMS SPI Motor Interface is a utility that easily allows you to set up the parameters of your Microstepping

MForce PowerDrive. It is available both on the CD that came with your product and on the IMS web site at

http://www.imshome.com/software_interfaces.html.

1. Insert the CD into the CD Drive of your PC.

If not available, go to http://www.imshome.com/software_interfaces.html.

2. The CD will auto-start.

3. Click the Software Button in the top-right navigation Area.

4. Click the IMS SPI Interface link appropriate to your operating system.

5. Click SETUP in the Setup dialog box and follow the on-screen instructions.

6. Once IMS SPI Motor Interface is installed, the Microstepping MForce PowerDrive settings can

be checked and/or set.

Table 2.6.1: Setup Parameters and Ranges

Color Coded Parameter Values

The SPI Motor Interface displays the parameter values using a predefined system of color codes to identify the

status of the parameter.

Black: the parameter settings currently stored in the device NVM will display as black.

Blue: Blue text indicates a changed parameter setting that has not yet been written to the

device.

Red: Red text indicates an out-of-range value which cannot be written to the device. When

an out-of-range parameter is entered into a field, the "set" button will disable, preventing the

value to be written to NVM. To view the valid parameter range, hover the mouse pointer over

the field. The valid range will display in a tool tip.

The color coding is illustrated in Figure 2.5.1.
