Configuring the Drive Module
Planning the System
Publication 1756-UM522B-EN-P - February 2003
Before programming, you must choose a Controller - Drive Module
interface (Controller Communication Format) for each Drive Module
in the system.
If you are going to use SynchLink, you must choose the SynchLink
data format, and a SynchLink network topology. This chapter covers
these topics.
Understanding the Controller - Drive Module Interface
You must configure communications between the ControlLogix
controller and the Drive Module by selecting a "Controller
Communication Format". A controller communication format is a set
of links that connects controller output tags to Drive Module sinking
parameters, and connects controller input tags to Drive Module
sourcing parameters. There are four controller communication formats
to choose from, depending on which module you are configuring:
• Velocity Control
• Position Control
• User-Defined Control
• Custom User-Defined Control
Each controller communication format contains both required
connections and user definable connections. You must use both
RSLogix 5000 and DriveExecutive to configure these connections. The
programming software will not allow you to choose Velocity Control
or Position control for the 1756-DMF30.
Once the module is created, the communications

format cannot be changed. The module must be
deleted and recreated.
Choosing the SynchLink Communication Formats
You must set a communications format for receiving data (Receive
Port Communications Formats) and transmitting data (Transmit Port
Communications Formats) in each module.
The following requirements apply to communication format choices:
