Overview and Applications
Synchronizing Multiple Axes for
NI 735x PCI and PXI stepper and servo motion controllers are for machine Parallel Mechanism Applications
builders and users who need the highest performance and a high-axis
count in a small space. The NI PXI-7358 is the first 8-axis stepper or servo
motion controller packaged as a 1-slot 3U PXI module. It offers many
Because NI 735x controllers can control up to eight axes, they are ideal
for high-axis parallel mechanisms where all axes need to be tightly
synchronized. Using the NI-Motion driver software, you can start all axes
advanced features, including sinusoidal commutation for brushless motors. at once and have each axis follow the acceleration and velocity profiles
NI 735x motion controllers are available in 2-, 4-, 6-, and 8-axis versions
for PXI and PCI.
you have defined. This is useful when working with parallel mechanisms
such as hexapods when the axes must move simultaneously.
Motion Control and LabVIEW Real-Time
Many motion applications require very high reliability and integration
with other types of I/O. NI PXI motion controllers are compatible with
the NI LabVIEW Real-Time Module, with which you can create an
integrated motion and I/O system that runs embedded in a real-time OS.
A PXI motion controller with a PXI RT Series controller can run LabVIEW
Static-Friction Compensation
The frictional force present before an object starts moving is called static
friction. Static friction is often higher than dynamic friction (frictional
force present during motion) and if the difference between the two is
large enough, it can make the system difficult to tune. The static-friction
compensation feature of the NI 735x motion controllers compensates for
Real-Time and function as a stand-alone Ethernet-based motion controller. this difference in friction for easier tuning and precise control. Piezoelectric
With this technology, you can create distributed motion control systems
that integrate tightly with data acquisition or vision.
systems exhibit high static friction and can benefit from the static friction
compensation feature of the NI 7350 series motion controllers. In addition,
to help you tune your system, NI offers the free Piezo Tuning Wizard.
After tuning your system using the Piezo Tuning Wizard, you can easily
program the system using LabVIEW software and NI Motion Assistant
just as you would program any other system.
I/O Capabilities
NI 735x motion controllers have diverse I/O that is useful in many motion
applications. You can use the 64 bits of digital I/O for a wide variety of
applications such as opening or closing valves or turning on and off
solid-state relays using the SSR adapter. These motion controllers also
have eight channels of 16-bit analog I/O useful for reading potentiometers
or other analog measurements.
High-Performance Stepper/Servo Motion Controllers
speed is the new buffered high-speed position capture for NI 735x
controllers. This feature captures positions based on a trigger from an
external source or from a data acquisition or machine vision device. The
high-speed capture can capture positions at rates of up to 2 kHz per axis.
Sinusoidal Commutation
Brushless servo motors require sinusoidal commutation. Although many
advanced motor drives have built-in commutation capability, many lower-
cost drives require the motion controller to provide commutation. With
sinusoidal commutation, offered by the NI 7350, you can obtain the
smoothest possible motion with a brushless servo motor and a lower
cost drive.
Additional Features
For the NI 735x controllers, your PID update rate can be 62.5 µs for up to
two axes. This means that for multiaxis applications, the PID rates can
be twice as fast as those for previous boards. An NI 735x also has
increased resolution for analog-to-digital conversion, giving you high
resolution for analog position feedback.
Note that when using the sinusoidal commutation feature, use two
axis resources for each drive you connect to. This is because two analog
outputs are needed to provide the commutation.

NI 7350 series motion controllers offer buffered breakpoints for precise
timing between motion and measurements or vision. Using this feature,
you can send a buffer of position breakpoints to the controller that
trigger a digital signal upon reaching the positions in the buffer. Buffered
breakpoints can trigger at rates as high as 2 kHz. For equally spaced
positions, you can use periodic breakpoints to achieve even higher
speeds of up to 4 MHz. With periodic breakpoints, you supply a position
modulus. Each time the position reaches that modulus position, the
breakpoint triggers. Another new feature that enhances integration
