Environmental statement

Control Techniques is committed to minimising the environmental impacts of its manufacturing operations and of its products throughout their life cycle. To this end, we operate an Environmental Management System (EMS) which is certified to the International Standard ISO 14001. Further information on the EMS, our Environmental Policy and other relevant information is available on request, or can be found at www.greendrives.com.

The electronic variable-speed drives manufactured by Control Techniques have the potential to save energy and (through increased machine/process efficiency) reduce raw material consumption and scrap throughout their long working lifetime. In typical applications, these positive environmental effects far outweigh the negative impacts of product manufacture and end-of-life disposal.

Nevertheless, when the products eventually reach the end of their useful life, they must not be discarded but should instead be recycled by a specialist recycler of electronic equipment. Recyclers will find the products easy to dismantle into their major component parts for efficient recycling. Many parts snap together and can be separated without the use of tools, while other parts are secured with conventional fasteners. Virtually all parts of the product are suitable for recycling.

Product packaging is of good quality and can be re-used. Large products are packed in wooden crates, while smaller products come in strong cardboard cartons which themselves have a high recycled fibre content. If not re-used, these containers can be recycled. Polythene, used on the protective film and bags for wrapping product, can be recycled in the same way. Control Techniques' packaging strategy prefers easily-recyclable materials of low environmental impact, and regular reviews identify opportunities for improvement.

When preparing to recycle or dispose of any product or packaging, please observe local legislation and best practice.

REACH legislation

EC Regulation 1907/2006 on the Registration, Evaluation, Authorisation and restriction of Chemicals (REACH) requires the supplier of an article to inform the recipient if it contains more than a specified proportion of any substance which is considered by the European Chemicals Agency (ECHA) to be a Substance of Very High Concern (SVHC) and is therefore listed by them as a candidate for compulsory authorisation.

For current information on how this requirement applies in relation to specific Control Techniques products, please approach your usual contact in the first instance. Control Techniques position statement can be viewed at:

4.2 Protective ground connections

WARNING

NOTE

The field controller must be connected to the system protective ground of the AC supply. The protective ground wiring must conform to local regulations and codes of practice. See section 4.3.1 MOV protective ground disconnect on page 17 for possible exceptions.

Ground loop impedance

The ground loop impedance must conform to the requirements of local safety regulations. The field controller must be connected by a protective ground connection capable of carrying the prospective fault current until the protective device (fuse etc,) disconnects the AC supply. The protective ground connections must be inspected and tested at appropriate intervals.

4.3 AC supply requirements

For detailed information regarding AC supply requirements, please refer to section

8.4 AC supply requirements on page 54.

4.3.1 MOV protective ground disconnect

In some special circumstances, for example during a high potential test or in certain situations with IT supplies and multiple generators there may be a requirement to disconnect the MOV protective ground connection. If the MOV protective ground connection is disconnected the immunity of the field controller to high voltage pulses is reduced. It is then only suitable for use with supplies having overvoltage category II, i.e. not for connection at the origin of the low voltage supply within a building. If the MOV to protective ground connection is not required then do not make a protective ground connection to the FXMP25.

4.4 Line reactors

The FXMP25, in common with all naturally commutated SCR drives, causes voltage notches at the input supply terminals. To avoid disturbances with other equipment using the same supply, the addition of external line inductance is strongly recommended in order to restrict the depth of notches imposed. This is generally not necessary where a dedicated transformer is used to supply the FXMP25. The following recommendations for added line inductance, have been calculated based on the power drive systems standard: EN 61800-3:2004 "Adjustable speed electrical power drive systems - Part 3: EMC requirements and specific test methods".

4.5 Cable and fuse size ratings

The selection of the correct fuse is essential to ensure the safety of the installation.

The AC supply inputs in the FXMP25 controller are fitted with auxiliary fuses for protection against short circuits in the FXMP25 controller and field-winding of the motor. These fuses will not protect the supply cables to the FXMP25 controller. There are other fuses are suggested to install in branch circuits. The branch circuit fuses will protect the supply cables to the FXMP25 controller. This section shows recommended cable sizes and fuse ratings for a number of current levels. Failure to observe this recommendation will cause a risk of fire.

Wiring must be in accordance with local regulations and codes of practice. The table shows typical cable sizes for power input and output wiring. In the event of a conflict, local regulations prevail.

Maximum continuous input currents are given in section 2.1 Ratings on page 9 to aid the selection of fuses and cabling. The cable sizing selected when installing the FXMP25 must comply with local wiring regulations. The information provided in this section is for guidance purposes only. The power terminals on the FXMP25 are designed to accommodate a maximum cable

size of 5.26 mm

(10 AWG).

The actual size depends on a number of factors including:

• Actual maximum continuous current

• Ambient temperature

• Cable support, method and grouping

• Cable voltage drop

Where continuous field current is reduced, the cable sizing selected can be appropriate for the reduced current. The field controller parameters should be programmed with the correct values.

When using reduced cable sizes, the branch circuit protection fuse rating needs to be reduced in line with the cable size selected.

Table 4-2 gives examples of the cable sizes based on IEC 60364-5-52 and UL508C/ NEC. The example cable sizes below assume three current-carrying conductors per cable or raceway and 40 °C ambient temperature.

Some special measures may be required in certain applications where the control cables are long or pass outside the building. See section 4.6.1 Surge immunity of control circuits - long cables and connections outside a building on page 22.

Radio frequency noise emission can occur from any of the power connections i.e. AC supply and field output terminals.

For many applications in heavy industrial environments the noise emission is not sufficient to cause interference to other equipment.

When radio frequency emission must be limited an input EMC filter can be installed. Shielded cables must be used for the field and the shield must be clamped to grounded metallic parts at both ends. The standard is met for cable lengths up to 100m.

4.6.1 Surge immunity of control circuits - long cables and connections outside a building

The input/output ports for the control circuits are designed for general use within machines and small systems without any special precautions. In applications where they may be exposed to high-energy voltage surges, some special measures may be required to prevent malfunction or damage. Surges may be caused by lightning or severe power faults in association with grounding arrangements which permit high transient voltages between nominally grounded points. This is a particular risk where the circuits extend outside the protection of a building.

As a general rule, if the circuits are to pass outside the building where the drive is located, or if cable runs within a building exceed 30 m, some additional precautions are advisable. One of the following techniques should be used:

1. Galvanic isolation, i.e. do not connect the control 0 V terminal to ground. Avoid loops in

the control wiring, i.e. ensure every control wire is accompanied by its return (0 V) wire.

2. Shielded cable with additional power ground bonding. The cable shield may be

connected to ground at both ends, but in addition the ground conductors at both ends of the cable must be bonded together by a power ground cable (equipotential

bonding cable) with cross-sectional area of at least 10 mm

, or 10 times the area of the signal cable shield, or to suit the electrical safety requirements of the plant. This ensures that fault or surge current passes mainly through the ground cable and not in the signal cable shield. If the building or plant has a well-designed common bonded network this precaution is not necessary.

3. Additional over-voltage suppression - for the analog and digital inputs and outputs, a zener diode network or a commercially available surge suppressor may be connected in parallel with the input circuit as shown in Figure 4-3 and Figure 4-4.

4.8 Serial communications

4.8.1 Introduction

The FXMP25 has a standard 2-wire EIA485 interface (serial communications interface) which enables all drive set-up, operation and monitoring to be carried out with a PC or controller if required. Therefore it is possible to control the drive entirely by serial communications without the need for a keypad or other control cabling.

The drive supports Modbus RTU configured as the default protocol, which is used with the PC-tools commissioning/start-up software as provided on the CD ROM with the product.

Safety information

information

Product

The serial communications port of the drive is a RJ45 socket, which is isolated from the power stage.

The communications port applies a 2 unit load to the communications network.

4.8.2 Serial communications connections

The FXMP25 has a serial communications port (serial port) as standard supporting two wire EIA(RS)-485 communications. See Table 4-8 for the connection details for the RJ45 connector.

The communications port applies a two-unit load to the communications network. Connectors 2, 3, 7 and shield must always be made to the serial communications port. Shielded cable must be used at all times.

USB/EIA232 to EIA485 Communications

An external USB/EIA232 hardware interface such as a PC cannot be used directly with the 2-wire EIA485 interface of the drive. Therefore a suitable converter is required.

FXMP25 User Guide 25

Issue Number: 3 www.controltechniques.com

Suitable USB to EIA485 and EIA232 to EIA485 isolated converters are available from

NOTE

Control Techniques as follows:

• CT USB Comms cable (CT Part No. 4500-0096)

• CT EIA232 Comms cable (CT Part No. 4500-0087)

When using one of the above converters or any other suitable converter with the FXMP25, it is recommended that no terminating resistors be connected on the network. It may be necessary to 'link out' the terminating resistor within the converter depending on which type is used. The information on how to link out the terminating resistor will normally be contained in the user information supplied with the converter.

4.8.3 Serial communications set-up parameters

The following parameters need to be set according to the system requirements.

This parameter defines the communications protocol used by the 485 comms port on the drive. This parameter can be changed via the drive keypad, via a Solutions Module or via the comms interface itself. If it is changed via the comms interface, the response to the command uses the original protocol. The master should wait at least 20 ms before sending a new message using the new protocol. (Note: ANSI uses 7 data bits, 1 stop bit and even parity; Modbus RTU uses 8 data bits, 2 stops bits and no parity).

When using the CT EIA232 Comms cable the available baud rate is limited to

19.2 k baud.

Parameters Pr 95 and Pr 96 select the address and baud rate respectively as detailed in section 6 Parameters on page 30.

Getting started

When in status mode pressing and releasing the MODE key will change the display from status mode to parameter view mode.

In parameter view mode, the left hand display flashes the parameter number and the right hand display shows the value of that parameter. The left hand display flashing

indicates that the up and down keys will select a different parameter to be

viewed. Holding the up key will cause the parameter number to increment to Pr 99.

Parameters Setting-up Technical data Diagnostics UL listing information

FXMP25 User Guide 27 Issue Number: 3 www.controltechniques.com

A single up key action when the last parameter is being displayed will cause the

MMM

parameter number to roll over to the lowest parameter available in the current mode.

Similarly holding the down key will cause the parameter number to decrement until

the lowest parameter available is reached and a single down key action will cause

the parameter number to roll under to Pr 99. Pressing and releasing the Mode key again will change the display from parameter view mode to parameter edit mode. In parameter edit mode, the right hand display flashes the value in the parameter being shown in the left hand display.

Pressing the MODE key in parameter edit mode will return the controller to

parameter view mode. If the MODE key is pressed again then the controller will

return to status mode, but if either of the up or down keys are pressed to change

the parameter being viewed before the MODE key is pressed, pressing the MODE key will change the display to parameter edit mode again. This allows the user to easily change between parameter view and edit mode while setting up the field controller.

Pressing the up and down keys simultaneously when editing a parameter will set the value to zero immediately. If no action is made while in parameter view or edit mode for 4 minutes the status mode is entered automatically.

5.2 Resetting the field controller

The controller can be reset using the keypad by pressing the mode key for at least two seconds in status or parameter view mode.

A reset is required in response to the following conditions:

• To reset the controller from a tripped state

• To implement a change in the value of certain parameters

5.3 Security

In the field controller’s default state no security is implemented, and any R/W parameter can be adjusted. If Pr 98 (user security code) is set to any value other than 0, then the value programmed will be taken as a security code. With a security code programmed, on power up, no R/W parameter can be altered. It will not be possible to change any parameter without first entering the security code. If Pr 98 is selected for viewing when a security code has been programmed the value indicated will be 0 (to prevent the code programmed from being read). When a security code has been programmed, any attempt to enter edit mode will cause the field controller to flash 'CodE' on the 4 digit display to prompt the user for a security

code (providing the parameter is R/W and not R/O). When the Up or Down keys are pressed, the 4 digit display will then show the code being adjusted and the 2 digit

display will indicate 'Co'. On setting the code, the user presses the MODE key. If the correct code has been entered then the field controller will switch to parameter edit mode on the parameter the user had selected to edit, but if the correct code has not been entered the field controller will return to parameter view mode.

If Pr 29 and Pr 30 have their default values of 50 and 75, the characteristic becomes one line and there will be a linear relationship between the field controller estimate of flux and the field current. If Pr 29 and Pr 30 are increased above 50 and 75 the field controller estimate of flux can included the effect of the non linearity. It is unlikely that information will be available to set-up these parameters, and so the values are determined during the rotating autotune test (in Mentor MP mode only). To set these values in stand alone mode use the following procedure:

• Ensure that Pr 29, Pr 30, Pr 68 and Pr 74 are set to their default values of 50 %, 75 %, 100 % and 100 % respectively.

• Set the speed demand to 1/4 of Base speed and run the machine up to speed and check the speed of the machine using a hand held device.

• If the machine speed is lower than 1/4 of Base speed (which is normally the case) adjust the Field compensation factor (Pr 74) down until the correct machine speed

is reached. If the machine speed is higher than

of Base speed (only possible if

the motor nameplate field current is low), adjust the Rated field current (Pr 70) up until the correct machine speed is reached.

•Set Pr 68 Maximum flux to 75 % and measure the actual speed of the machine (speed 75)

•Set Pr 68 Maximum flux to 50 % and measure the actual speed of the machine (speed 50).

• Stop the machine and set Pr 68 Maximum flux back to 100 %.

•Set Pr 29 Motor saturation breakpoint 1 = 50 x set speed / actual speed (Speed 50)

•Set Pr 30 Motor saturation breakpoint 2 = 75 x set speed / actual speed (speed 75).

Recommendations

Half control

Normally use half control, since this generally produces a lower amplitude of current ripple. This results in lower torque ripple in motor.

Full control

Full control causes the SCR bridge to force the field current more rapidly towards zero at each half cycle. This increases the amplitude of the current ripple, but gives faster control of the field current level. Use full control under the following conditions:

• When very rapid field weakening is required

• If the natural decay of the field defined by is slower than the acceleration

Getting started Parameters

Refer to Mentor II User Guide Issue 14 page 95 for Mentor II block diagram.

Thermal overload in Mentor II mode works by forcing current feedback to zero causing the relay to operate. When Mentor II is enabled, this causes the drive to trip FdL (field loss). When in the disabled state, FdL trip is not active on Mentor II, and therefore following loss of feedback Mentor II will advance the firing angle to the end stop which will cause the output of the FXMP to reach maximum voltage set by the front end stop Pr 6.21.

When using FXMP 25 with Mentor II, Pr 6.21 must be set in order to avoid field over voltage conditions during fault conditions. (Refer to Pr 6.21 on page 64 in the Mentor II User Guide for an example calculation). FXMP relay and Mentor II logic functions should be used to set Pr 6.13 to 0 to disable firing pulses during fault conditions in the disabled state.

Ambient temperature operating range: 0 °C to 55 °C (32 °F to 131 °F) Field output current derating must be applied at temperature >40 °C (104 °F).

Safety information

Minimum temperature at power-up: The FXMP25 will power up at -15 °C (5 °F).

Maximum humidity:

The FXMP25 can operate in environments up to a maximum relative humidity: 90 % non-condensing at 50 °C.

8.7 Storage

Storage temperature range: -40 to 70 °C.

Storage time is 2 years.

Electrolytic capacitors in any electronic product have a storage period after which they require reforming or replacing.

The DC bus capacitors have a storage period of 10 years.

The low voltage capacitors on the control supplies typically have a storage period of 2 years and are thus the limiting factor.

Low voltage capacitors cannot be reformed due to their location in the circuit and thus may require replacing if the FXMP25 is stored for a period of 2 years or greater without power being applied.

It is therefore recommended that the FXMP25 is powered up for a minimum of 1 hour after every 2 years of storage.

FXMP25

FXMP25 status = tripped Trip type (FdL =Field loss)

The display on the FXMP25 gives various information about the status of the field controller. These fall into three categories:

• Trip indications

• Alarm indications

• Status indications

Users must not attempt to repair a faulty FXMP25 or carry out fault diagnosis other than replace internal fuses or through the use of the diagnostic features described in this chapter. Under no circumstances must the casing of the FXMP25 be opened when the AC supply is connected. Faulty units must be returned to an authorized Control Techniques distributor for repair.

9.1 Trip indications

If the unit trips, the field output is disabled and the FXMP25 ceases to control the field. The left hand display indicates that a trip has occurred, and the right hand display shows the trip.

Trips are listed alphabetically in Table 9-1 based on the trip indication shown on the FXMP25 display.

Example

The FXMP25 display shows an FdL trip on the display as shown in Figure 9-1 below:

Figure 9-1 Typical example of trip display

The above graphic shows the resultant display following an FdL trip. This indicates a field loss condition as described in Table 9-1 on page 61 overleaf.
