Introduction

The CM1-T is an Ethernet based Cool Muscle. It offers all the functionality of the standard Cool Muscle but enables connections over TCP/IP, UDP, Modbus-TCP and EtherNet/IP. This variant of the Cool Muscle cannot be daisy chained.

The following terminology is important to understand how to understand this document and how to operate the motor.

TermDescription
Protocols

The protocols are the different Ethernet languages the user can implement to communicate to the controls methods. They are

  • TCP/IP and UDP
  • Modbus-TCP
  • EtherNet/IP
Control method

The control method indicates how the motor controller is communicated with, updated and controlled. Control methods are

  • CML- the motor runs logic and program banks
  • Direct Control - the motor receives position, speed, acceleration/deceleration and torque values to dynamically move between targets
Mode of operation

The mode of operation is how the motor controller operates in Direct Control. This is how the motor's motion controller generates a set of outputs to the motor driver. These are typically

  • CML mode - traditional operation of the motor
  • Profile mode - operate the motor by in position and/or speed control
  • Torque mode - operate the motor by limiting torque and speed.



The following diagram shows how the protocols break down to the different modes of operation

Connections and Port

General Usage and Operation

CML Programming

Refer to the RT3 Programming Manual for details on using CML. You will find information on the following in this manual:

As stated in the introduction the CM1-T is a standalone motor and cannot be used in a daisy-chain configuration. As such there are features in CML related to multiple motor networks which will not function if programmed.

Features that cannot be used in the CM1-T:

Modbus-TCP

Modbus-TCP reads and writes to all motor registers. 

EtherNet/IP

See the EtherNet/IP section of this document for details on using the CM1-T with EtherNet/IP

Connecting in Control Room

Control Room is the Cool Muscle Windows application to program the motors. It is typically not used for run-time operation but this can depend on the user's requirements. Control Room can open up a connection in either standard CML mode or by Modbus-TCP. Two instances of Control Room can be opened if the user needs to use Modbus-TCP and CML simultaneously.

Note: You cannot program in CML mode if the connection is opened in Modbus Mode and you cannot use the Modbus Window if the connection is opened not in Modbus Mode.

To connect to a motor use the TCP/IP options, Connect to IP and Enable Modbus Mode functions on the Connection tab as shown below.
