Overview and Applications
Distributed Control with LabVIEW Real-Time
You can use the NI-Motion driver software with the NI LabVIEW Real-Time
Module. With this technology, you can create powerful, distributed
motion control systems using a PXI RT Series controller, the LabVIEW
Real-Time Module, and a PXI-734x motion controller. You can program
this type of system using LabVIEW on a separate computer. The main
advantages of a real-time system are high reliability and the capability
to create powerful distributed motion control solutions that connect to
the main PC using standard Ethernet.
NI 734x motion controllers are for end users and machine builders who
need to develop powerful applications quickly and easily. With the
proper drive, you can use NI 734x motion controllers for stepper/servo
motor control and piezoelectric control. These controllers also have four
general-purpose analog inputs that you can use in simple application
monitoring or as feedback for closed-loop control.
Features
NI 734x controllers offer advanced features such as blended motion
trajectory control and fully coordinated circular, linear, point-to-point,
gearing, and vector-space control in either embedded motion operation
or host-centric programming environments. NI also provides contouring
capability for more complex moves. NI 734x controllers use a high-
performance motion controller architecture. The CPU and DSP components
operate together to optimize closed-loop control, automate systems control,
and implement motion command processing functions. The onboard CPU
uses an embedded real-time operating system that has event-driven
multitasking control. With this state-of-the-art approach, several motion
control programs and processes can operate simultaneously on the
controller, independently of the host PC and with no outside program
interaction unless the host program or user configuration initiates it.
