Safety Information

The option c ard and its associated drive are intended as componentsfor professional
incorporationinto complete equipment or systems. If installed incorrectlythe drive may
present a safety hazard. The drive uses high voltages and currents,c arries a high level
of stored electricalenergy,and isused tocontrolmechanicalequipmentthat can cause
injury.
Close attention is required to the electrical installation and the system design to avoid
hazards either in normal operation or in the event of equipmentmalfunction. System
design,installation, commissioning and maintenancemust be carried out by personnel
whohave the necessary training and experience. They must read this safety information
and this InstallationGuide carefully.
Carefulconsideration must be given tothe functions ofthe drive and option c ard which
mightresultin a hazard, either through theirintendedfunctions, e.g. auto-start,or through
incorrectoperationdue toa faultor trip,e.g.stop/start,forward/reverse,m aximum speed,
loss of a communications link.
In any application where a malfunctionof the drive oroption card could lead todamage,
loss or injury, a riskanalysis mus t be carried out, and where necessary, further measures
taken to reduce t he risk.To ensuremechanical safety, additionalsafetydevicessuch as
electro-mechanical interlocks may be required. The Drive mustnot be used in a safety­critical application withoutadditionalhigh-integrity protectionagainsthazards arising
from a malfunction.

General Information

The manufacturer accepts no liability for any consequences resultingfrominappropriate,
negligent or incorrectinstallation or adjustment of the optional operating parameters of
the equipment or from mismatching the Drive with the motor.

1 Mechanical Installation

NOTE

1.1 Unidrive and UD70

Before attempting to installoption modules or cards, e nsure that the U nidrive
or Me ntor II is switched off. AC Drives should be left for 5 minutes to ensure
that the DC link capacitorshave completely discharged.

• Slidethe UD70 moduleunder the displaypanelof theUnidrive,and push the
modulein untilthe connector locates withthe plug insidethe Unidrive.

WARNING

• Applyfirm pressure, andthe module will click securely into place.

• To remove the UD70, pullfirmly on the black tab,and the module will
disengagefrom the connector.

Do not attempt to remove the UD70 modulewhile the Unidrive is still powered
up, as this may caus e damage to the Unidrive.

1.2 Mentor II and MD29/MD29AN

The MD29 is fitted ontothe 40-way pin header (PL1)on theMDA2B circuit board.
The supplied mounting pillars should beattached to the MDA2B on the Mentor II.

• Tilt the MD29at an angle and locate thefirstfew pins into theMD29 header.

• Tiltthe boardto horizontal to engage the restof thepins. Pressfirmly
downwardsto firmly fix the MD29to the header and 4 mounting pillars.

NOTE

WARNING

UD70/MD29 Installation Guide 4
Issue Number: 3 www.controltechniques.com

Take care when locating the board onto this connector - do not force it on.
Excessiveforce may bend and break the pins of the header.

When removing an MD29, unsnap the MD29 from the pillars before gently w orking
the MD29 off the header. Do nottilt the MD29 excessively to one side, as this may
bend and breakthe end groups of pins on the header.

Do not attempt to remove the MD2 9 while the Mentor II is stillpowered up,as
this may cause damage to the Mentor I I.

2.6 I/O Box PortConnections (MD29 Only)

The I/O Box port is marked “PL2”and is only availableon the MD29. The terminal
connections are shown in the table below. Operation of this port is automatic, and
no configuration is necessary.

Pin Function Description

NOTE

To us e the I/O Box with UD70 or MD29AN, connect it to the R S485 port, and
select Mode 10 communications.

2.7 Digital I/O Connections

The RS485 connector has 2 TTL digitalinputs and 1 TTLdigitaloutput.They are
used in conjunction with the Timer/Counter unit. (Forfurtherdetails,refer to the
Userguide forthe UD70 or MD29.)

NOTE

NOTE

The0VSC isisolatedfrom the U nidrive or Me ntor II0V, and shouldnotbe used
as the reference 0V for the TTL digital inputs and output.

If a digitalinput is open-circ uit or connected to +5V, this willbe readby #86.01
(input 0) or #86.02(input 1) as logic 0. These parameters will change to logic 1
when the inputs are connectedto 0V Digital on pin 9.
The digitaloutput will give +5V when #86.03 isset tologic 0, and 0Vwhen setto
logic1. Thedigitaloutput is rated to a maximum of 15mA. The maximum lengthof
cablethatshould be connected to theseterminalsis 0.5 metres, so buffering will be
required forlonger lengths of cable,and for interfacingto different logic levels.

The Digitalinputs a nd output must be connected to 0V Digital (pin 9), NOT
OVSC (pin 1). The inputs and output will not work properly if connected to
OVSC, as pin 1 is isolated fromthe Drive. Noise generatedalong the screen
of theserial communications cable may cause spurious operation, and
damagetotheUD70orMD29mayresult.

3 RS485 Port Configuration

TheRS485portcanbeusedtocommunicatewiththeDriveusingControl
Techniques' standard software communications packages such as UniSoft,
MentorSoft, CTFile and Systemwis e. (Refer to the Help file in Unisoft, MentorSo ft,
etc. f or connection details.) The ANSIprotocolis the standard protocol used bythe
ControlTechniques'softwarepackages,but Modbus RTU and ASCII modes are
alsosupported as slave nodes only.
The RS485 portis configured by settingcertainuser parameters on theUnidriveor
MentorII. These control individualfeaturesabout the port.Any changes take effect
when the configurat ion parameters are storedand t he UD70 or MD29 isreset.
The following parameters used to configure the RS485 port.

Range: 11 to 99, excluding 00 to 09, 10, 20, 30, 40, etc for ANSI.

Default: 11
Every node on an ANSI or Modbus network MU ST be assigned a unique serial

address. Changes to the node address will not take effect until theparameters
have been stored, and the U D70 or MD29 has been reset.
The serial address ensures that only the intendednode responds to commands
issuedby thenetwork master control ler. Eachnode should be assigned a unique
addressBEFORE itis connected to the RS485 network.

3.3 RS485 Port C ommunications Modes

Unidrive: #17.06 Mentor II: #14.02
The serial communications mode selector determines the mode of operation of the
RS485 serial port, and the protocol supported. Only slavemodes are described

3.3.1 Standard CT ANSI Protocol

3.3.2 Modbus RTU

here. (Modes 6 to 9,11 and 12 require DPL code to control the RS485.)

Mode 1 - 4 Wire ANSI Slave Mode (Default)
Mode 5 - 2 Wire ANSI Slave Mode
The UD70 and MD29 will communicate using the Control Techniques' standard
ANSIprotocolwith a 4-wireor 2-wire connection. This mode allowstheUnidriveor
MentorII t o communicatewith standard CT software packages,such asUniSoft,
MentorSoft, SystemWise, etc.
Menu 0 parametersare notaccessiblethrougha UD70 or MD29. Referto the
User's Guide for MD29 or UD70 for a deta iled description of the ANSI protocol.

Mode 13 - 4 WireModbus RTU Slave Mode
Mode 15 - 2 WireModbus RTU Slave Mode
The UD70 and MD29 will communicate using the Modicon ModbusRTU protocol
witha 4-wireor 2-wire connection. Thedata frame usedfor Modbus RTU is 1 start
bit, 8 databits, no parity, 2 stopbits. (Evenparitywith 1 stop bitis NOT currently
supported. )
The following MOdbus RTU commands aresupported:
FC3 PRESET SINGLE REGISTER

bit,7 databits, no parity, 2 stop bits.
The following Modbus ASCIIcommands are supported:
FC3 PRESET SINGLE REGISTER
FC6 PRESET MULTIPLE R EGISTERS

The maximum numberof registers that can be transferred on a single message is
limited to 20, and the range of allowed node addresses is limited from 1 to 99.

3.3.4 Master/Slave

Mode 2 - Master Mode
Mode 3 - Slave Mode
In Mode 2, the node acts as a master,and continuously broadcastsa source
parameter,as definedby thePointer parameter, from the RS485 port at a f ixed
datarate of 9600 bits/sec.The valueof thesource parameter is scaledto ±16000.
In Mode 3, the node acts as a slave to receivethe continuous data stream
