Overview and Applications

✓

NI 7330 series devices are low-cost stepper motion controllers for

point-to-point applications. These low-cost motion controllers

provide new solutions for machine builders who need simple,

straightforward motion control without a lot of extra features.

Unlike other low-cost motion controllers, NI 7330 controllers

still have a variety of powerful features including:

S-curve

Configurable move complete criteria

Software limits

High-speed capture

Blending

✓

Upgradeable firmware

NI Motion software API

Number of axes per 62.5 microsecond PID rate

Static PWM outputs

DIO

Analog-to-digital converter

Stepper output rate

Encoder rate

✓

• Linear interpolation for coordinating multiple axes.

• Real-time system integration for directly communicating

with data acquisition or image acquisition boards

32 bits

12-bit A/D

4 MHz maximum

20 MHz maximum

✓

• High-performance stepper generation for ensuring smooth

motion at high velocities.

NI-Motion Driver Software

NI 7330 devices use the NI-Motion driver. The advantage of this is

that if your application needs change in the future, you can easily

upgrade your hardware without having to change your code. You can

also take advantage of any firmware updates with the field-

upgradable firmware.

Integration Capabilities

Like other NI Motion controllers, NI 7330 controllers offer powerful

integration capabilities with both data acquisition and machine

vision. One of the most powerful is the RTSI bus or PXI trigger bus

capability that you can use to communicate directly with other

devices without extra wiring and without consuming bandwidth on

the host bus. An NI 7330 is ideal when using stepper motors for

applications where only simple motion is required.
