FM-3 Programming Module Reference Manual

If Selector.Select2 is active, Selector.Select1 is inactive, and Selector.Select0 is active, then

the total binary value is as follows:

= 1, S

= 0, and S

= 1. Therefore,

Total Binary Value = (1 x 2

) + (0 x 2

) + (1 x 2

)

Total Binary Value = 4 + 0 + 1

Total Binary Value = 5

Therefore, when Selector.SelectorInitiate activates, then Selector.Selection5 will activate.

Example 2:

If Selector.Select2 is inactive, Selector.Select1 is active, and Selector.Select0 is active, then

the total binary value would be as follows:

= 0, S

= 1, and S

= 1. Therefore,

Total Binary Value = (0 x 2

) + (1 x 2

)

Total Binary Value = 0 + 2 + 1

Total Binary Value = 3

Therefore, Selector.Selection3 would activate.

The Selector.Select lines can change without any action until the Selector.SelectorInitiate

destination is activated.

Selector.Selection sources can be tied to any destination in the Assignments view. Figure 39

shows the four selection lines being tied to Index 0 through Index 3 initiates. By doing this,

we could initiate up to four indexes with only two select lines and a selector initiate. This can

help minimize the number of inputs required to initiate a large number of indexes or

programs.

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. External controllers, such as a PLC or other

motion controllers, may be connected to affect or monitor the device’s operation.

E Series 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 has an additional eight

input and four output lines.
