Table 2.3.1: 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.
