Safety Information

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

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.

Introduction

2 Introduction

This document will explain how to operate an MCH Drive using BACnet protocol on a Master-Slave/Token-

Passing (MS/TP) LAN. 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). Some of the information contained in this document was

provided by the ANSI/ASHRAE 135-2001 standard. Refer to http://www.bacnet.org for more information.

2.1 MS/TP Communications

MS/TP communication is maintained by a Master & Slave relationship between the devices on the LAN.

All communication is initiated by Master devices. The token passes network mastership from one Master

device to another. Slave devices never initiate a service request. They only respond to service requests

from master devices. The Native BACnet implementation in MCH Drives is for an MS/TP Slave device.

Therefore, only devices that support static device binding will be able to communicate with an MCH drive.

For an MS/TP EIA-485 network use shielded, twisted-pair cable with a characteristic impedance between

100 and 130 ohms. Maximum recommended length of an MS/TP segment is 1200 meters (4000 feet)

with AWG 18 cable. Maximum number of nodes (unit loads) per segment is 32 (as speciﬁed by the EIA-

485 standard). Because MS/TP uses non-return to zero (NRZ) encoding, the polarity of the connection to

the cable is important. The non-inverting input of the EIA-485 transceiver is designated as “+” and the

inverting input as “-”. Connect a termination resistance of 120 ohms (± 5%) at each of the two ends of the

segment medium. Ground the shield at one end only to prevent ground currents from being created. Each

MCH drive is equipped with 100k ohm local bias resistors.

2.2 MS/TP Physical Layer

Communication is half duplex. Bytes are transmitted using NRZ encoding with 1 start bit, 8 data bits, no parity

and 1 stop bit. All bytes are transmitted with the least signiﬁcant bit ﬁrst. Communication is asynchronous

with no more than 20 bit times of idle time between any two bytes of a frame. The communication baud

rate for MCH Series Drives is 9600 bps. The bit sequence is as follows:

DATA

START 1 2 3 4 5 6 7 8 STOP

Drive Setup & Programming

3 Drive Setup and Programming

Most drive parameters (including those required for serial communications) are not accessible through the

LAN. 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 BACnet® Drive are explained

in sections 3.1-3.3 herein.

3.1 Added Programming Parameters

60 SERIAL TIMEOUT This parameter makes the serial watchdog timeout period selectable. (Section 3.4)

85 DEVICE NUM EX This parameter is used to extend the device number to its full 22-bit range of

0 to 4194303. If the device number of the drive exceeds a value of 65535, this

parameter should be set to the value of bits 16-22 of the device number. Otherwise

this parameter should be set to 0.

86 DEVICE NUMBER This parameter holds the value of bits 0-15 of the drive’s 22-bit device number. It

can be used by itself to represent a device number in the range of 0 to 65535. If the

device number exceeds 65535, then DEVICE NUM EX must also be used.

Example: The device number is 124 (00007Ch). The value of bits 16-22 (DEVICE NUM EX) is

00h or 0. The value of bits 0-15 (DEVICE NUMBER) is 007Ch or 124.

Example: The device number is set to its default value of 1240000 (12EBC0h). The value of

bits 16-22 (DEVICE NUM EX) is 12h or 18. The value of bits 0-15 (DEVICE NUMBER)

is EBC0h or 60352.

NOTE

The values of the DEVICE NUMBER and DEVICE NUM EX parameters are also appended to the

object name of the drive to ensure that it is unique network-wide.

Example: If the device number of the drive is set to its default value of 1240000 (12EBC0h),

the resulting object name for the device will be ‘AC Tech VFD 18-60352’.

3.2 Omitted Parameters and Selections

Drive Setup & Programming

3.3 Modiﬁed Parameters and Selections

24 AUTO SOURCE The default selection for this parameter has been changed to KEYPAD. Refer to

Section 3.4 Serial Communications Setup for more information.

32 HZ MULTIPLIER The default setting for this parameter has been changed to 30.00. Refer to Section

3.4 Serial Communications Setup for more information.

56 SERIAL LOSS The selections for this parameter are FAULT (default) and PRESET#3. The functionality

of this parameter is described in detail in Section 3.4 Serial Communications Setup.

57 SERIAL The default selection for this parameter has been changed to WITH TIMER to provide

limited “out-of-thebox” serial communication with the drive.

58 MAC ADDRESS This parameter has been renamed to be consistent with BACnet nomenclature. The

minimum and maximum values for this parameter have also been changed to 0

and 254, respectively, in accordance with ANSI/ ASHRAE Standard 135-2001. The

default value is 128. Refer to Section 3.4 for more information.

3.4 Serial Communication Setup

The factory default values of the drive parameters have been set to allow the monitoring of all MCH BACnet

points. Write commands will not be accepted without proper modiﬁcation to these drive settings. One

exception to this is STOP commands, which are always accepted over the LAN. For serial start and/or serial

speed and setpoint control, modify the setting of Drive Parameter #30 (Control). The drive parameters that

are required for serial communications, including Drive Parameter #30, are described herein.

24 AUTO SOURCE This parameter must be set to KEYPAD for the drive speed or setpoint to be modiﬁed

over the LAN.

30 CONTROL This parameter should be set to accommodate the speciﬁc application intent:

NORMAL Serial start and serial speed/setpoint commands are invalid.

NORM NO HAND Same as NORMAL except the HAND/OFF/AUTO, herein referred to

as H/O/A, is limited to settings of OFF and AUTO.

SERIAL SPEED Serial start commands are invalid. Serial speed/setpoint

commands are valid in AUTO H/O/A.

S SPD/NO HAND Same as SERIAL SPEED except H/O/A is limited to settings of OFF

and AUTO.

SERIAL AUTO Serial start and serial speed/setpoint commands are all valid in

AUTO H/O/A. This setting forces the drive to be started over the

LAN when in AUTO H/O/A.

S AUTO/NO HND Same as SERIAL AUTO except H/O/A is limited to settings of OFF

and AUTO.

Serial STOP commands are accepted over the LAN regardless of this parameter setting.

RG-MHBAC 6

Drive Setup & Programming

NOTE

• Drive Parameter #30 (CONTROL) must be set to SERIAL AUTO or S AUTO/NO HND in order

to start the drive over the LAN.

• The upper left corner of the drive display must indicate SSTOP for a serial start command

to be accepted by the drive.

• If the display reads KSTOP (keypad stop) then the AUTO START or HAND START button

must be pressed to clear the keypad stop condition.

• If the display reads RSTOP (remote terminal stop) then there is an open external contact

that needs to be closed.

• If the drive is a standalone drive or has an option box, make sure that the TB1-to-

TB2 contact is being made.

• If the drive has a bypass, make sure that the drive is in AUTO H/O/A and that all

of the safety and customer start contacts are closed (speciﬁcally the B3-to-B4

contact which is not made when the drive leaves the factory).

56 SERIAL LOSS This parameter sets the action to be taken in the event that the Drive Parameter #30

(Control) is set to SERIAL SPEED and the LAN had modiﬁed the speed or setpoint

command prior to a serial watchdog timeout occurrence. The options for this

parameter are FAULT (default) and PRESET#3.

If FAULT is selected and the drive is running when a serial watchdog timeout occurs

the drive will trip into a SERIAL FAULT stopping the drive and taking it out of serial

control. A fault reset command (issued via the Clear Fault point), a keypad stop or a

terminal stop is required to clear the fault. A stop command from the LAN will also

clear the fault if it is the highest priority command in the priority array.

If PRESET#3 is selected, Drive Parameter #30 (Control) is set to SERIAL SPEED and

the drive is running when a timeout occurs, the drive will continue to run but will get

its speed command from Drive Parameter #3 (PRESET #3). If the drive is stopped

(KSTOP, RSTOP, SSTOP or FAULT), placed in HAND or OFF or serial communications

are restored, the drive will return to its normal speed/setpoint reference.

When Drive Parameter #30 (Control) is set to SERIAL SPEED, the speed reference

MUST be the drive keypad (-KEY, -MKB, -AKB or -SER) for the serial loss action to

take effect.

If Drive Parameter #30 (Control) is set to SERIAL AUTO the serial loss action is ignored

and the drive trips into a SERIAL FAULT stopping the drive and taking it out of serial

control.

Drive Setup & Programming

57 SERIAL This parameter needs to be set to either WITH TIMER (default) or W/O TIMER for

the drive to communicate with the LAN. Serial communications will not work if this

parameter is set to DISABLED.

58 MAC ADDRESS This parameter contains the address of the MCH drive. It is adjustable from 0-254

and has a factory default value of 128.

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

minimum value of 10 seconds and maximum value of 65535 seconds. The default is

30 seconds. If no action is to be taken when a serial watchdog timeout occurs, Drive

Parameter #57 (Serial) should be set to W/O TIMER. This will disable the watchdog

timer. Otherwise Drive Parameter #57 (Serial) should be set to WITH TIMER.

If the LAN has started the drive or has modiﬁed the Speed Source Selection (MV1),

the Keypad Speed Command (AV1) or the Keypad Setpoint Command (AV2) and a

serial watchdog timeout occurs, the drive is taken out of serial control.

If Drive Parameter #30 (Control) is set to SERIAL AUTO and the drive was running

when the timeout occurred, the drive will also stop the motor by tripping into a

SERIAL FAULT. A fault reset command, issued via Clear Fault (BV1), a keypad stop

or a terminal stop is required to clear the fault.

If Drive Parameter #30 (Control) is set to SERIAL SPEED, then the action to be taken

when a timeout occurs is determined by Drive Parameter #56 (Serial Loss).

When Drive Parameter #30 (Control) is set to SERIAL SPEED the speed reference

being used MUST be set to the drive keypad (-KEY, -MKB, -AKB) or the LAN (-SER)

for the serial watchdog to be active. When Drive Parameter #30 is set to SERIAL

AUTO the serial watchdog will be active with any speed reference.

Also, if the LAN has written to the keypad speed command, the speed source

changes from keypad to serial and the keypad speed command cannot be changed

using the drive keypad. In order for the drive keypad to take control of the keypad

speed command, the drive H/O/A must be toggled to HAND or OFF to release serial

control of the corresponding BACnet® object. The same is true of the keypad

setpoint command and the speed source selection.
