ABB INSUMMCU2 MCU2A02V24 INSUM® PROFIBUS Gateway Manual SW 2.1

Objective

The objective of this Users Ganual is to provide the technical information of Motor Control Unit (MCU). This manual should be studied carefully before installing, parameterizing or operating the Motor Control Unit. It is expected that the user has a basic knowledge of physical and electrical fundamentals, electrical wiring practices and electrical components.

The manual refers to INSUM MCU Hardware –4, Software V3.0d.

This document should be used along with the MCU Parameter Description V3.0d, which provides detailed information about parameters and their applications.

For more information on the INSUM system, please see documentation as mentioned in section 1.2.

Product Overview

MCU in general

Motor Control Unit (MCU) is a product range of electronic motor control and protection devices with a fieldbus interface. Typically MCU is located into the motor starter, where it’s main task is protection, control and monitoring of a 3-phase/1-phase AC motor and motor starter equipment. MCU is connected to the other starter equipment via digital and analog I/O and to other MCU and control system(s) via fieldbus interface. The product range of MCU offers two variations of devices:

• MCU1 is a basic low-end motor controller device for motor and starter equipment protection, control and monitoring. 

• MCU2 is a high-end motor controller device based on the MCU1. MCU2 offers more comprehensive set of motor and starter equipment protection, control and monitoring functions. Additionally some process control related functions are included.

The functionality is presented in a list format in appendix ‘MCU HW and SW FUNCTIONAL REFERENCE’.

Mechanical structure

MCU units

MCU consists of four parts: 

 • Baseplate • Main Unit 

 • Current Measurement Unit 

 • Voltage Unit (option for MCU2 only)

Baseplate Baseplate is a unit mechanically fixed to drawer mounting rail. All the outgoing/incoming wires of the MCU (except main currents and PTC) are connected to Baseplate. Main Unit and Current Measurement Unit are plugged to Baseplate.

Main Unit Main Unit is a unit containing the electronics of the motor control unit. Main unit is plugged to the Base plate.

Current Measurement Unit Current Measurement Unit contains the current measurement transformers. It is plugged to the Baseplate and additionally fixed by the Main Unit. 2 primary ranges are available: 0.1…3.2 A and 2.0…63 A

Voltage Unit (option for MCU2 only) Voltage Unit contains three phase voltage measurement transformers and electronics for auxiliary power supply 2 (UAUX2). It is connected to the Baseplate with flat cable and installed side by side to drawer mount ing rail with MCU main unit.

Voltage unit detection is done as automatic function by the use of internal code signaling.

MCU enclosure material

The enclosure of the MCU is made of polycarbonate with 10 % glassfibre. Flammability rating of the mate rial is UL 94 V-0 and material is halogen free.

Colour of the enclosure is RAL 7012. Material is recyclable and is shown by the respective marking inside the enclosure parts.
