each individual bit of the Status Word(s), as well as hexidecimal and decimal format for each Status Word.

Using Pack Bits Status Words
Once the Status Word(s) have been configured by the user, they can be utilized by fieldbus communications (i.e. Modbus,
EtherNet I/P, Profibus, DeviceNet, etc.) or within a user program. Figure 91 below shows an example in which the user will
read Status Word 0 from the drive via Ethernet I/P.

Assignments View

External control capability is provided through the use of assignments to the sources (Unidrive SP/Digitax ST Inputs,
EZMotion Inputs, and any SM I/O module Inputs) or the destinations (Unidrive SP/Digitax ST Outputs, EZMotion Outputs, and
any SM I/O 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 option modules.
External controllers, such as a PLC or other motion controllers, may be connected to affect or monitor the device's operation.
The Unidrive SP/Digitax ST is equipped with up to six input lines (three can be configured as Input or Output) and up to five
output lines (three can be configured as Input or Output and two are Relay Outputs). EZMotion has an additional four input
and two output lines.
The Unidrive SP/Digitax ST's input and output lines can be accessed through the two removable 11-pin control connectors.
The SM-EZMotion input and output lines are located on the front face of the SM-EZMotion module.
All inputs and outputs are configured as sourcing and are designed to operate from a +10 Vdc to +30 Vdc power source. The
user is responsible for limiting the output current to less than 10 mA or less for each digital output.
Assignments View
The Assignments view is used to tie a Source to a Destination. Destinations are found on the right side of the Assignments
view, and are functions that need to be triggered, such as Index Initiates, Program Initiates, Jog Initiates and so on. Sources
are located on the left side of the Assignment view and reflect the status of events that occur in the drive. These events are
based on drive activity. Figure 128 shows an example of the Assignments view.
