Universal Motion Interfaces
Connecting to Motor Drives
When interfacing to a third-party power drive and motor, it is
important to consider the amount of current to drive the motor and
the connectivity to a motor drive. National Instruments provides a
wide selection of options for interfacing to motors. You can interface
to 2-phase stepper motors with 4 A peak current using National
Instruments power drives. In addition, you can interface to 5-phase
stepper motors and other stepper motors outside the range of
NI MID Series drives using National Instruments UMI interfaces.
For DC-brush servo motors that need up to 10 A peak current, you
can use National Instruments power drives and controllers. For DC
brushless, AC, and other types of servo motors outside the range of
NI MID Series drives, an NI UMI interface simplifies connections to
the motor and controller.
