Overview

Product overview

Key product information and technical features.

The MID-7602 occupies the power-drive position in a stepper motion system rather than serving as the motion controller itself. NI's published connection diagram places the MID-7604/02 drive between an NI PCI/PXI/FW-7344 motion controller and a stepper stage.

Configuration should account for NI's correction to the original user guide: the step and direction signals are active high, not active low. The NI-Motion readme recommends changing the stepper polarity setting in Measurement & Automation Explorer (MAX) accordingly.

Two-axis stepper drive architecture.
Step/direction command interface with active-high signal polarity.
Included in NI's documented controller-to-stepper-stage connection arrangement using the SHC68-C68-S cable.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

How many axes does the MID-7602 drive?

The MID-7602 is the two-axis stepper drive in the MID-7604/7602 family.

What polarity should be used for step and direction?

NI's documentation correction specifies active-high polarity. NI recommends changing the stepper polarity setting in MAX to active high rather than following the original user guide's active-low statement.

Which controller connection is documented by NI?

NI's Polytec PI stepper-stage connection diagram shows an NI PCI/PXI/FW-7344 motion controller connected to the MID-7604/02 drive through an SHC68-C68-S cable.
