Second Processor Options

for Unidrive and Mentor II

Part Number: 0460-0098

Issue Number: 3

Safety Information

The option card and its associated drive are intended as components for professional

incorporation into complete equipment or systems. If installed incorrectly the drive may

presenta safety hazard.The drive uses high voltages and currents, carries a high level

of stored electrical energy, and is used to control mechanicalequipment that can cause

injury.

Close attention is required to the electrical installation and the system design to avoid

hazards either in normaloperation or in the event of equipment malfunction. System

design, installation, commissioning and maintenance must be carried outby personnel

who have the necessary training and experience. They must read this safety information

and this Installation Guide carefully.

Careful consideration must be given to the functions of the drive and option card which

mightresultin ahazard,eitherthrough their intendedfunctions,e.g.auto-start,orthrough

incorrectoperationdue toa fault ortrip,e.g.stop/start, forward/reverse,maximum speed,

loss of a communications link.

In any application where a malfunction of the drive or option card could lead to damage,

loss orinjury, a riskanalysis mustbe carried out, and where necessary, furthermeasures

takento reduce the risk.To ensure mechanicalsafety, additional safety devicessuch as

electro-mechanical interlocks may be required. The Drive must not be used in a safety-

critical application withoutadditional high-integrity protection against hazards arising

from a malfunction.

General Information

The manufacturer accepts no liability for any consequences resulting from inappropriate,

negligent or incorrect installation or adjustment of the optional operating parameters of

the equipment or from mismatching the Drive with the motor.

1 Mechanical Installation

Before attempting to install option modules or cards, ensure that the Unidrive

or Mentor II is switched off. AC Drives should be left for 5 minutes to ensure

that the DC link capacitors have completely discharged.

1.1 Unidrive and UD70

• Slide the UD70 module under the displaypanel ofthe Unidrive, and push the

module in until the connector locates with the plug inside the Unidrive.

NOTE

• Apply firm pressure, and the module will click securely into place.

• To remove the UD70, pull firmly on the black tab, and the module will

disengage from the connector.

Do notattemptto remove the UD70 module while the Unidriveis still powered

up, as this may cause damage to the Unidrive.

1.2 Mentor II and MD29/MD29AN

The MD29 is fitted onto the 40-way pin header (PL1) on the MDA2B circuitboard.

The supplied mounting pillars should be attached to the MDA2B on the Mentor II.

• Tilt the MD29 at an angle and locate the first few pins into the MD29 header.

Issue Number: 3 www.controltechniques.com

• Tilt the board to horizontal to engage the rest of the pins. Press firmly

downwards to firmly fix the MD29 to the header and 4 mounting pillars.

Take care when locating the board onto this connector - do not force it on.

Excessive force may bend and break the pins of the header.

When removing an MD29, unsnap the MD29 from the pillars before gently working

the MD29 off the header. Do not tilt the MD29 excessively to one side,as this may

bend and break the end groups of pins on the header.

Do not attempt to remove the MD29 while the Mentor II is stillpowered up, as

this may cause damage to the Mentor II.

2 Electrical Installation

2.1 UD70

The UD70 provides a dedicated RS232 programming port (Connector C) and a

general purpose RS485 communications port (Connector D)..

Connectors A and B provide the connectors for high speed fieldbus communication

options, if fitted. Refer to the appropriate fieldbus option User Guide for full fieldbus

connection details.

2.2 MD29

The MD29 provides a dedicated RS232 programming port (Connector SK2) and a

generalpurpose RS485 communications port (Connector PL1). In addition, the

MD29 also has a dedicated RS485 port (Connector TB1) for use with the Control

Techniques I/O Box.

2.5.1 4 Wire RS485 Network

The diagram below shows the connections required for a 4 wire RS485 network,

using a master controller with an RS485 port. The UD70 and MD29 can be

configured to act as master controllers, but this requires DPL programming to

control the network.

An RS232-to-RS485 converter is required to allow a standard PC serial port to

communicatewitha4wireRS485network.

2.5.2 2 Wire RS485 Network

The diagram below shows the connections required for a 2 wire RS485 network,

using a master controller with an RS485 port. The UD70 and MD29 can be

configured to act as master controllers, but this requires DPL programming to

control the network.

An RS232-to-RS485 converter with “intelligent transceiver switching” (also known

as “magic” RS485 converters) is required to allow a standard PC serial port to

communicatewitha2wireRS485network. Anexampleofa“magic”converteris

the MA485F converter from Amplicon.

A “magic” converter is not required is the master contoller has an RTS control

output. This output is enabled when the master is transmitting, and disabled

when the master is not transmitting. Control Techniques software packages

(UniSoft, MentorSoft and SystemWise) do NOT switch the RTS line.
