The SNAP-SCM-MCH16 motion control host module is a serial communication module that links up to four SNAP-SCM-BB4 motion control breakout boards with a SNAP PAC brain or rack-mounted controller. When mounted on a SNAP PAC rack and connected to a breakout board, a single SNAP-SCM-MCH16 module allows a SNAP PAC controller running a PAC Control™ programming strategy to control up to 16 stepper motors.
This guide shows you how to install and use the SNAP PAC Motion Control Subsystem, which provides an integrated hardware and software toolset for controlling multi-axis stepper motors. The SNAP PAC Motion Control Subsystem consists of a SNAP-SCM-BB4 breakout board working with the SNAP-SCM-MCH16 host communication module and a free library of motion commands, which are used with Opto 22 PAC Control software.
Since the introduction of G4 input/output modules in the mid-1980s, Opto 22 has sold millions. And 20 years later, these remain some of the company’s best-selling products. Like most Opto 22 modules, G4’s are guaranteed for life. In order to make this guarantee, the company must submit the modules to rigorous testing before they’re shipped to customers.
The G4 Handler is the machine used to perform these tests. When the 20-year-old servos on the G4 Handler needed to be replaced, an economical replacement could not be found. Instead, the G4 Handler’s servo motors were replaced with stepper motors.
Watch the G4 Handler video case study.
This case study describes how the SNAP PAC System Motion Control Subsystem was used with the new stepper motors to control module testing and gather test data.
This document lists all Opto 22 part numbers that have the Underwriters Laboratory (UL) approval.
This CAD file includes drawings for the SNAP-SCM-BB4 breakout board. The SNAP-SCM-BB4 is part of the SNAP PAC Motion Control Subsystem.
The Motion Control example strategies show how to achieve four different motion control maneuvers using OptoMotion commands in a PAC Control strategy. You can use the example strategies as a starting point for creating your own control strategies.
