UMI Accessory User Guide — UMI-Flex6
You can configure the functionality of the Inhibit Inputs using switches
SW1 and SW3. These inputs can be configured as a group as active low
global inhibits or as active high global E-Stops. When configured as global
inhibits, an active low signal applied to any input asserts the inhibit output
lines on the UMI. When configured as global E-Stops, an active high signal
applied to any input asserts the inhibit output lines on the UMI and asserts
the E-Stop signal back to the FlexMotion controller. See Table 1 for switch
SW1 and SW3 settings.
Analog Input Terminal Blocks
For analog input wiring, the UMI-Flex6 has two, 6-position terminal
blocks. Each connector provides access to four of the eight analog input
channels on the FlexMotion boards. Refer to Figure 23 to help you locate
the analog input terminal blocks on your UMI-Flex6 accessory. See
Figures 29 and 30 for analog input terminal block pinout information.
