1 Safety Information

1.1 Warnings, Cautions and Notes

1.1.1 General

Some parts of Lenze controllers (frequency inverters, servo inverters, DC controllers) can be live, moving and rotating. Some surfaces can be hot.

Non-authorized removal of the required cover, inappropriate use, and incorrect installation or operation creates the risk of severe injury to personnel or damage to equipment.

All operations concerning transport, installation, and commissioning as well as maintenance must be carried out by qualiﬁed, skilled personnel (IEC 364 and CENELEC HD 384 or DIN VDE 0100 and IEC report 664 or DIN VDE0110 and national regulations for the prevention of accidents must be observed).

According to this basic safety information, qualiﬁed skilled personnel are persons who are familiar with the installation, assembly, commissioning, and operation of the product and who have the qualiﬁcations necessary for their occupation.

1.1.2 Application

Safety Information

Drive controllers are components designed for installation in electrical systems or machinery. They are not to be used as appliances. They are intended exclusively for professional and commercial purposes according to EN 61000-3-2. The documentation includes information on compliance with EN 61000-3-2.

When installing the drive controllers in machines, commissioning (i.e. the starting of operation as directed) is prohibited until it is proven that the machine complies with the regulations of the EC Directive 98/37/EC (Machinery Directive); EN 60204 must be observed.

Commissioning (i.e. starting drive as directed) is only allowed when there is compliance to the EMC Directive (89/336/EEC).

The drive controllers meet the requirements of the Low Voltage Directive 73/23/EEC. The harmonised standards of the series EN 50178/DIN VDE 0160 apply to the controllers.

The availability of controllers is restricted according to EN 61800-3. These products can cause radio interference in residential areas. In the case of radio interference, special measures may be necessary for drive controllers.

1.1.3 Installation

Ensure proper handling and avoid excessive mechanical stress. Do not bend any components and do not change any insulation distances during transport or handling. Do not touch any electronic components and contacts. Controllers contain electrostatically sensitive components, which can easily be damaged by inappropriate handling. Do not damage or destroy any electrical components since this might endanger your health! When installing the drive ensure optimal airﬂow by observing all clearance distances in the drive's user manual. Do not expose the drive to excessive: vibration, temperature, humidity, sunlight, dust, pollutants, corrosive chemicals or other hazardous environments.

Safety Information

1.1.4 Electrical Connection

When working on live drive controllers, applicable national regulations for the prevention of accidents (e.g. VBG 4) must be observed.

The electrical installation must be carried out in accordance with the appropriate regulations (e.g. cable cross-sections, fuses, PE connection). Additional information can be obtained from the regulatory documentation.

The regulatory documentation contains information about installation in compliance with EMC (shielding, grounding, ﬁlters and cables). These notes must also be observed for CE-marked controllers.

The manufacturer of the system or machine is responsible for compliance with the required limit values demanded by EMC legislation.

1.1.5 Operation

Systems including controllers must be equipped with additional monitoring and protection devices according to the corresponding standards (e.g. technical equipment, regulations for prevention of accidents, etc.). You are allowed to adapt the controller to your application as described in the documentation.

DANGER!

• After the controller has been disconnected from the supply voltage, do not touch the live

components and power connection until the capacitors have discharged. Please observe the corresponding notes on the controller.

• Do not continuously cycle input power to the controller more than once every three minutes.

• Close all protective covers and doors during operation.

WARNING!

Network control permits automatic starting and stopping of the inverter drive. The system design must incorporate adequate protection to prevent personnel from accessing moving equipment while power is applied to the drive system.

2 Introduction

This document explains how to connect an MCH Drive to a LonWorks® network. It is intended as a serial communications supplement only and will not discuss normal drive operations. For more information regarding normal drive setup and functionality, refer to the MCH Installation and Operation Manual (MH01).

LonWorks® technology is a complete platform for implementing control network systems. These networks consist of intelligent control devices or nodes that interact with their environment and communicate with each other using a common, message based protocol (LonTalk®). A LonWorks® network can consist of up to 32,385 nodes divided into 255 subnets (127 nodes/subnet).

2.1 Hardware Description

To connect to a LonWorks® network, the MCH Drive utilizes an Anybus-S® Drive Proﬁle Embedded Interface Card that supports Version 1.1 of the LonMark® 6010 Functional Proﬁle for Variable Speed Motor Drives. This Anybus-S LonWorks (ABS-LON®) module is located inside of the bypass or option box that is attached to the MCH Drive.

The ABS-LON® module communicates according to the LonTalk® protocol. This means that it can communicate with all LonWorks® nodes that comply with this protocol, but it does not necessarily mean that all services available in the LonTalk® protocol are supported.

Introduction

The ABS-LON® module uses the FTT-10A (Free Topology Twisted Pair) transceiver from Echelon Corporation. This is the most commonly used twisted-pair media in building automation and this architecture supports star, bus and loop wiring. The FTT-10A transceiver connects to a twisted pair cable with a baud rate of 78 kbit/s. The FTT-10A transceiver appears as a high impedance to the network when unpowered, and does not interfere with network communications when powered down.

Figure 1 identiﬁes the components of the communications module intended for user interaction.

Drive Setup & Programming

3 Drive Setup and Programming

Most drive parameters (including those required for serial communications) are not accessible through the LonWorks® interface. They can only be accessed by entering the Programming Mode of the drive itself. Refer to the MCH Installation and Operation Manual (MH01) for more information. The parameter information in manual MH01 is based on the standard MCH Series Modbus™ Drive. The differences between the drive programming parameters described in the manual and those that exist in the MCH Series LonWorks® Drive are explained in sections 3.1-3.4 herein.

3.1 Added Programming Parameters

60 SERIAL TIMEOUT This parameter makes the serial watchdog timeout period selectable.

(Section 3.5)

86 MOTOR RATED SPEED This parameter allows the user to enter the nominal speed of the motor

in RPM. This value is required for LON parameter nvoSpeedActRpm to function properly. This parameter has a minimum value of 1 RPM and a maximum value of 65000 RPM. The default is 1800 RPM.

89 MOTOR RATED FREQUENCY This parameter allows the user to enter the nominal frequency of the

motor in Hz. This value is required for many LON parameters (including nviDrvSpeedStpt and nvoDrvSpeed) to function properly. This parameter has a minimum value of 0.00 Hz and a maximum value of 650.00 Hz. The default is 60.00 Hz.

125 APP REVISION This parameter allows the user to view the version of the application

software installed in the ABS_LON module. This parameter is used for troubleshooting and to establish compatibility between the drive software and the ABS_LON module. If this parameter is displaying a value of 0104 or 9999, contact AC Tech.

126 CPI REVISION This parameter allows the user to view the version of the common proﬁle

interface software installed in the ABS_LON module. This parameter is used for troubleshooting and to establish compatibility between the drive software and the ABS_LON module. If this parameter is displaying a value of 0124 or 9999, contact AC Tech.

127 CFG REVISION This parameter allows the user to view the version of the AC Tech

conﬁguration software installed in the ABS_LON module. This parameter is used for troubleshooting and to establish compatibility between the drive software and the ABS_LON module. If this parameter is displaying a value of 0001 or 9999, contact AC Tech.
