FM-3 Programming Module Reference Manual
I/O Setup Group
The I/O Setup group contains four views that control input and output functions as well as
other drive functions. These views are as follows: Selector, Assignments, Input Lines and
Output Lines. These can be viewed by expanding I/O Setup by simply clicking on any one of
the setup views underneath the I/O Setup.
Assignments
External control capability is provided through the use of assignments to the sources (Drive
Inputs and Module Inputs) or the destinations (Drive Outputs and Module Outputs).
Assignments provide a mechanism for the user to define the internal and external dynamic
control structure to separate complex motion profiles. These functions directly correspond to
any input or output line on the drive or the FM-3 module. External controllers, such as a PLC
or other motion controllers, may be connected to affect or monitor the device’s operation.
The drives are equipped with five optically isolated input lines (one dedicated to a Drive
Enable function) and three optically isolated output lines. The FM-3 module has an additional
eight input and four output lines.
The drive’s input and output lines can be accessed through the removable 10-pin I/O
connector (J6), or through the 44-pin command connector (J5). The FM-3 input and output
lines are located on the front of the FM-3 module.
All inputs and outputs are configured as sourcing and are designed to operate from a +10 to
30 VDC power source. You are responsible for limiting the output current to less than 200
mA for each digital output.
Assignments View
The Assignments View not only displays information but also makes assignments regarding
the source and the destination.
