Configuring an Ethernet motion system

Configuring a motion system is a process with many different configuration options. Basic Ethernet motion system setup requires these steps in the Logix Designer application:
Step
Process
Reason
1.
Add an Ethernet motion module
Identifies the motion module being used to the Logix controller
2
Create an axis for a motion drive
An axis is used to define forward and backward motion in one direction.
3.
Create a motion group
Consolidates the axes into a control set to provide coordinated motion.
4.
Configure the axis properties
Defines the individual properties for the axis, including motor feedback, axis configuration, and scaling.
For the purposes of this quick start, assume this configuration:
  • An Ethernet motion module, either Kinetix or PowerFlex
  • Motor feedback
  • Position loop axis configuration
  • A new controller project with an Ethernet communications module configured
Add an Ethernet motion module
  1. Right-click the Ethernet network (node) and choose
    New Module
    .
  2. In
    Select Module Type
    , under
    Module Type Category Filters
    , select the appropriate checkbox to filter the selections and select the motion module from the list.
  3. Click Create. The
    New Module
    dialog box appears.
    • In
      Name
      , type a name for the module.
    • (optional) In
      Description
      , type a description.
  4. In
    Ethernet Address
    specify an IP address.
  5. Under
    Module Definition
    , click
    Change
    . The
    Module Definition
    dialog box appears.
  6. In
    Electronic Keying
    select
    Compatible Module
    .
    IMPORTANT:
    The electronic keying feature automatically compares the expected module, as shown in the configuration tree, to the physical module before communication begins.
    When you are using motion modules, set the electronic keying to either
    Exact Match
    or
    Compatible Keying
    .
    Never use
    Disable Keying
    with motion modules.
  7. In
    Connection
    , select
    Motion
    .
  8. (optional) In
    Power Structure
    , select the appropriate power structure from the list (Example: 2094-BC01-MP5-M) and then select
    Verify Power Rating on Connection
    .
    TIP: Power structure identifiers are not required for all modules. If needed, these numbers are found on the hardware, in the device documentation, and on the bill of materials. Many modules have power structures defined by default.
  9. Click
    OK
    to apply the changes.
