Introduction
command outputs. All stepper axes support full, half, and microstepping
applications.
Hardware
The 7344/7334 controllers have high-performance capabilities because of
the advanced dual-processor architecture that uses a Motorola MC68331
real-time 32-bit CPU, combined with an Analog Devices ADSP-2185
digital signal processor (DSP) and custom field programmable gate arrays
(FPGAs). The first-in-first-out (FIFO) bus interface and powerful function
set provide high-speed communications while off-loading complex motion
functions from the host PC for optimum command throughput and system
performance.
With the 7344 controllers, you can use full onboard programming to
execute up to 10 simultaneous motion programs in a preemptive, real-time
multitasking operating system environment.
The 7344 features motion profiles that are controlled with enhanced
PID/PIVff servo updates at 62 µs per axis. With all 7344/7334 controllers,
each axis has motion I/O for end-of-travel limit and home switch inputs,
breakpoint output, trigger input, and encoder feedback rates up to 20 MHz.
The 7344/7334 controller also has non-dedicated user I/O including 32 bits
of digital I/O and four analog inputs for ±10 V signals, joystick inputs, or
monitoring of analog sensors. Additionally, the 7344/7334 analog inputs
can provide feedback for loop closure.
RTSI
The 7344/7334 controllers support National Instruments’ Real-Time
System Integration (RTSI) bus. The RTSI bus provides high-speed
connectivity between National Instruments’ products, including image
acquisition (IMAQ) and data acquisition (DAQ) products. Using the RTSI
bus, you can easily synchronize several functions to a common trigger or
timing event across multiple motion, IMAQ, or DAQ devices.
