Description

The easy-to-use SNAP PAC Motion Control Subsystem

provides an integrated hardware and software toolset for

controlling multi-axis stepper motors. The subsystem consists

of:

•

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 I/O unit.

When mounted on an I/O unit 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. The module snaps into an

Opto 22 SNAP PAC mounting rack right beside digital and

analog modules. LED indicators are provided to indicate

Transmit and Receive on each port.

Each SNAP-SCM-BB4 breakout board is equipped with a

Magellan

direction signals for up to four stepper motor systems. You can

daisy-chain up to four breakout boards connected to a single

module. The module’s external connector provides lines to

power one breakout board; additional boards require a

separate power source. The SNAP-SCM-BB4 breakout board is

designed to be mounted using a DIN-rail system.

The OptoMotion commands supports many of the

acceleration, breakpoints, interrupts, and time intervals. In

addition, you can execute motion-related actions such as

smooth stops, stepping, and position adjustments.

Calculating Power Requirements

When you assemble a SNAP rack that includes a SNAP-SCM-

MCH16, you need to calculate the power requirements to

make sure that the rack’s power supply is adequate for the

combined current needed by the brain or controller and all

the I/O modules. For more information and power

requirements worksheets, see the SNAP I/O Wiring Guide (form

#1403) as well as the wiring appendices in the the SNAP PAC

Brain User's Guide (form #1690) and the SNAP PAC R-Series

Controller User’ s Guide (form #1595).

Powering the Breakout Board

When using power from the SNAP-SCM-MCH16 module,

you can use only one breakout board. The breakout board

should be connected with a cable under two meters long, and

the stepper logic must be isolated from the drive output. If

you are uncertain how to achieve this, consider using an

auxilliary power supply instead.

When using an auxilliary power supply, you can choose

either the 5 VDC auxilliary input or the 8 to 32 VDC auxilliary

input on the breakout board.
