Introducing the TeSys T Motor Management System

Overview

This chapter introduces the TeSys T motor management system and its companion devices.

Presentation of the TeSys T Motor Management System

Aim of the Product

The TeSys T motor management system offers protection, control, and monitoring capabilities for single-phase and three-phase AC induction motors.

The system is flexible, modular, and can be configured to meet the requirements of applications in industry. The system is designed to meet the needs for integrated protection systems with open communications and a global architecture.

Highly accurate sensors and solid-state full motor protection provide better utilization of the motor. Complete monitoring functions enable analysis of motor operating conditions and faster responses to prevent system downtime.

The system offers diagnostic and statistics functions and configurable alarms and trips, allowing better prediction of component maintenance, and provides data to continuously improve the entire system.

TeSys T Motor Management System

The two main hardware components of the system are the LTMR controller and the LTME expansion module.

The microprocessor-based LTMR controller is the central component in the system that manages the control, protection, and monitoring functions of single-phase or three‑phase AC induction motors.

The LTMR controller is designed to work over the following networks:

An Ethernet network either through Modbus/TCP communication protocol or through EtherNet/IP communication
The Modbus network
The PROFIBUS DP network
The CANopen network
The DeviceNet network

The system can be configured and controlled:

Using an HMI (Human Machine Interface) device: Magelis^™ XBT or TeSys T LTMCU.
Using a PC running SoMove^™ with the TeSys T DTM.
Using a PLC connected to the system via the communication network.
Using the Ethernet Web server (for LTMR Ethernet controller only.)

Components such as external motor load current transformers and ground current sensors add additional range to the system.

LTMR Controller

The following table introduces the functions of the LTMR controllers:

NOTE: LTMR Ethernet controllers communicating over an Ethernet network can communicate either using the Modbus/TCP communication protocol or using the Ethernet/IP communication protocol.

Both protocols are loaded in the controller. The controller is pre-configured to communicate through Modbus/TCP protocol. Changing its configuration allows to switch to Ethernet/IP protocol.
