Snap-on ferrite beads for the power supply cable(s) (included with your NI UMI-7772 or 
NI UMI-7774). You must use a separate ferrite bead for each power supply cable. Refer to 
the 

NI UMI-7772/7774 User Guide and Specifications

 for installation information.

NI SMD-7620/7621 stepper drive

NI or third-party stepper motor

Note

NI offers stepper motors matched to the NI SMD-7620/7621. Refer to 

ni.com/motion

 for motor options. National Instruments highly recommends using 

these motors for the best user experience.

(Optional) ENC-7741 encoder for ST23 motors or ENC-7742 encoder for ST34 motors

Encoder cable to connect the encoder to the UMI-7772/7774
(NI part number 783025-01)

Ethernet connection and cable for the NI SMD-7620/7621

AC input cable for the NI SMD-7620/7621

Software

NI-Motion 7.6 or later driver software 

Tip
