When reading through this Design Guide, you will come across various symbols that require special attention.

The symbols used are the following:

This symbol indicates a general warning.

NB!:

This symbol indicates something to be noted by the reader.

This symbol indicates a high-voltage warning.

VLT®FCM Series

Introduction

MG.03.H3.02 - VLT is a registered Danfoss trademark

VLT®FCM Series

All operations must be carried out by appropriately trained personel. Use all lifting facilities provided

e.g. both lifting points if fitted or single lifting point if fitted*. Vertical lifting - Prevent uncontrolled rotation. Lift machine - Do not lift other equipment with motor lifting points only. Before installation check for fan cover damage, shaft damage, foot/mounting damage, and loose fasteners. Check nameplate details. Ensure level mounting surface, balanced mounting, not misaligned. Gaskets, and/or sealants, and guards must be correctly fitted. Correct belt tension.

Please observe derating rules, see "Special conditions".

*Note: maximum hand lift is 20 kg below shoulder, but above ground level. Max. gross weights:

- Frame size 80: 15 kg

- Frame size 90 & 100: 30 kg

- Frame size 112: 45 kg

- Frame size 132: 80 kg

2. Correct protective earthing of the equipment must be established, the user must be protected against supply voltage, and the motor must be protected against overload in accordance with applicable national and local regulations. Use of RCD’s(ELCBrelays)isdescribed in chapter 10.

3. The earth leakage currents are higher than 3.5 mA. This means that the FC motor requires a fixed, permanent installation as well as reinforced protective earthing.

■ Warning against unintended start

1. The motor can be brought to a stop by means of digital commands, bus commands, or references, while the frequency converter is connected to mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, t stop functions are not sufficient .

2. While parameters are being changed, the motor may start.

3. A motor that has been stopped may start if faults occur in the electronics of the FC motor, or if a temporary overload or a fault in the mains supply ceases.

hese

The voltage on the FC motor is dangerous when the motor is connected

to mains. Incorrect installation of the FC motor may lead to material damage or serious injury, or it may be fatal. Consequently, the instructions in this manual as well as national and local rules and safety regulations must be complied with. Touching the electrical parts may be fatal, even after the mains supply has been disconnected. Wait at least 4 minutes.

- Installation must be fused and isolated correctly.

- Covers and cable entries must be fitted.

NB!:

It is the user’s or certified electrician’s responsibility to ensure correct earthing and protection in accordance with applicable

national and local requirements and standards.

■ Safety regulations

1. The VLT DriveMotor (FC motor) must be

disconnected from mains if repair work is to be carried out. Check that the mains supply has been disconnected and that the necessary time has passed (4 minutes).

■ Integration of frequency converter and motor

The Danfoss VLT frequency converter integrated onto the asynchronous motor gives infinite speed control in one unit.

The VLT DriveMotor FCM 300 Series is a very compact alternative to the ordinary solution with VLT frequency converter and motor as separate units. The frequency converter is attached instead of the motor terminal box, and it is no higher than the standard terminal box, nor widerorlongerthanthemotor(seechapter6).

Installation is made extremely easy. Panel space is not a problem. There is no need for special details on wiring to meet the EMC directive, since motor cables are not necessary. The only connections are mains and control connections.

VLT®FCM Series

Factory-set adaption between frequency converter and motor gives precise and energy efficient control in addition to eliminating pre-setting on site.

The FC motor can be used in stand alone systems with traditional control signals, such as start/stop signals, speed references and closed loop process control or in multiple drive systems with control signals distributed by a field bus.

Combination of fieldbus and traditional control signals and closed loop PID control is possible.

give notification when ordering.

Protection:

• Thermal overload protection of motor

and electronics.

• Monitoring of the intermediate circuit voltage

ensures that the inverter cuts out if the intermediate circuit voltage gets too high or too low.

• If a mains phase is missing, the inverter will cut

out when a load is placed on the motor.

■ Handling the FC motor

Handling and lifting of VLT DriveMotors (FC motors) must only be undertaken by qualified personnel. Full product documentation and operating instructions must be available together with tools and equipment necessary for safe working practice. Eyebolts and/or lifting trunnions supplied with the FC motor are designed to support only the weight of the FC motor, not the weight of the FC motor and any auxcillary equipment attached to it. Be absolutely sure that cranes, jacks, slings and lifting beams are capable of carrying the weight of equipment to be lifted. Where an eyebolt is provided with the motor, this should

■ Bearings

The standard solution is fixed bearing in the drive side of the motor (shaft output side). To avoid static indention, the storage area should be vibration free. Where exposure to some vibration is unavoidable, the shaft should be locked. Bearings may be fitted with a shaft locking device which should

be screwed down until its shoulder is firmly against the face of the stator frame to be lifted.

■ Installation of the FC motor

FC motors must be installed with adequate access for routine maintenance. A minimum of 0.75m of working space around the motor is recommended. Adequate space around the motor, particularly at the fan inlet (50 mm), is also necessary to facilitate airflow. Where several FC motors are installed in close proximity, care must be taken to ensure that there is no recirculation of exhausted warm air. Foundations must be solid, rigid and level.

NB!:

Electrical installation Do not remove the top foil inside the inverter part, as this is a part of the protective arrangements.

VLT®FCM Series

itting pinions, pulleys and couplings.

These should be bored to our standard limits and fitted on the shaft with a screwing motion. Attention must be paid to correct guarding of all moving parts.

Tapping of fitments onto the FC motor shaft, with a hammer or mallet, causes bearing damage. This results in an increase in

bearing noise and a significant reduction in bearing life.

NB!:

Max. length of mounting bolts penetrating the B14 flange, see section Dimensions in this chapter.

■ Alignment

When the application calls for direct coupling, the shafts must be correctly aligned in all three planes. Bad alignment can be a major source of noise and vibration.

Maximum permissible external axial and radial loads in N

Allowance must be made for shaft endfloat and thermal expansion in both axial and vertical planes. It is preferable to use flexible drive couplings.

a. Remove the inverter part, the fan cover and

the fan which is keyed to the shaft extension. Loosen and remove bearing cover screws and endshield bolts/studs.The endshields should then be eased off their spigots.

b. The rotor can now be carefully withdrawn from

the stator, taking care not to damage the stator bore and both stator and rotor windings.

c. Having dismantled the motor, maintenance can be

carried out to remove all dirt. For this purpose, the use of an air line supplying dry compressed air under comparatively low pressure is best, as

a high velocity air-stream can force dirt into the spaces between the windings and insulation, etc. Grease-removing solvents can cause damage to impregnating varnish or insulation

■ Forced ventilation (FV) units (Not yet available)

In some applications the fan built on to the motor shaft do not give sufficient cooling for operation at low speed. That problem is solved by mounting a FV unit.

Typical applications are for example conveyors, spindles and other contant torque (CT) applications

VLT®FCM Series

where the customer wants a wide control range without reduction in torque down to low speed.

The VLT Drive Motor yields full continuous torque down to low speed with FV built on. The forced vent enclosure is IP 55. Not approved according to UL.

■ FCM 30 0 Thermal Protection

The thermal protection of FC and motor is covered in the following way:

1. Overload situations are handled by the calculated

electrical load (I

Xt).

2. Missing ventillation and high ambient temperature is handled by the temperature measurement. The derating for low speed (due to missing ventillation) is not incoporated in the electrical load calculaton but taken care of by the temperature measurement. Forced ventillation is thus automaticly covered.

Electrical load The current is measured in the DC link and the estimated load is calculated. The level of the electrical load is set at an output torque of 105%. Above that level a counter is increased, below the level it is decreased. The counter starts at zero. When the counter reaches 100, the unit trips. At 98 the warning indication goes on (LED and status word).

The value can be read in parameter 537 (LCP: Heat sink temp.).

The temperature levels seem to be high, but due to a local heating of the sensor the practical levels of the inside air temperature are approx. 10 deg C lower.

■Quick menu mode versus Menu mode

The FC motor series can be used for practically all assignments, which is why the number of parameters is quite large. Also, this series offers a choice between two programming modes - a Menu mode and a Quick menu mode.

• The Quick menu takes the user through a number

of parameters that may be enough to get the motor to run nearly optimally, if the factory setting for the other parameters takes the desired control functions into account, as well as the configuration of signal inputs/outputs (control terminals).

• The Menu mode makes it possible to select

and change all parameters at the user’soption. However, some parameters will be "missing", depending on the choice of configuration (parameter

100), e.g. open loop hides all the PID parameters.

In addition to having a name, each parameter is linked up with a number which is the same regardless of the programming mode. In the Menu mode, the parameters are divided into groups, with the first digit of the parameter number (from the left) indicating the group number of the parameter in question.

Regardless of the mode of programming, a change of a parameter will take effect and be visible both in the Menu mode and in the Quick menumode.

■Quick Setup via Quick menu

The Quick Setup starts with pressing the [QUICK MENU] key, which brings out the following read-out on the display:

Reset zeroes the FC motor after an alarm; however, not all alarms can be reset without disconnecting from mains.

Coasting stop, inverse is used for making the FC motor run freely to stop. Logic ’0’ leadstocoastingstop.

Reset and coasting stop, inverse, is used for activating coasting stop at the same time as reset.

Logic ‘0’ leadstocoastingstopandreset. Quick stop, inverse is used for stopping the

motor in accordance with the quick-stop ramp (set in parameter 212).

Logic ’0’ leads to a quick-stop. DC breaking, inverse is used for stopping the

motor by energizing it with a DC voltage for a given time, see parameters 126-132.

Please note that this function is only active if the settings of parameters 126-132 is different from

0. Logic ’0’ leads to DC braking. Stop inverse is activated by interrupting the voltage

to the terminal. This means that if the terminal has no voltage, the motor cannot run. The stop will be effected in accordance with the selected ramp (parameters 207/208).

None of the above-mentioned stop commands are to be used as disconnection switch in connection

with repairs. Cut mains instead.

Start clockwise is used if the motor shaft is only to be able to rotate clockwise when starting.

Should not be used with Process, closed loop mode. Start counter-clockwise, on is used if the motor shaft is

to be able to rotate counter-clockwise when started. Should not be used with Process, closed loop mode. Jog is used for overriding the output frequency to the

jog frequency set in parameter 213. The ramp time can be set in parameter 211. Jog is not active if a stop command has been given (start-disable).

Jog overrides stand-by. Freeze reference - freezes the actual reference. The

Start, is selected if a start/stop command is desired. Logic ’1’ = start, logic ’0’ = stop (stand-by).

Latched start - if a pulse is applied for min. 20 ms, the motor will start, provided no stop command. The motor stops if Stop inverse is activated briefly.

Reversing is used for changing the direction of rotation of the motor shaft. Logic "0" will not lead to reversing. Logic "1" will lead to reversing. The reversing signal only changes the direction of rotation; it does not activate the start function.

Should not be used with Process, closed loop mode.

Start reversing, is used for start/stop and for reversing

Speed up and Speed down are selected if digital

control of the up/down speed is desired (motor potentiometer). This function is only active if Freeze reference or Freeze output has been selected.

As long as there is a logic ‘1‘ on the terminal selected for speed up, the reference or the output frequency will increase.

As long as there is a logic ‘1‘ on the terminal selected for speed down, the reference or the output frequency will be reduced.

Pulses (logic ‘1‘ minimum high for 20 ms and a minimum pause of 20 ms) will lead to a change of

speed of 0.1% (reference) or 0.1 Hz (output frequency). with the same signal. No start signal is allowed at the same time. Acts as latch start reversing, provided latch start has been chosen for another terminal.

Should not be used with Process, closed loop mode.

Function:

AC brake [4] can be selected to improve braking. With the new AC brake function it is possible to control the time of increased motor losses, still protecting the motor thermally. This function will yield a braking torque between 80 and 20 % in the speed range up to base speed (50 Hz). Above base speed the extra braking will gradually disappear.

[0] [4]

is set that determines how long the output frequency can be lower than the frequency set in parameter 404 Sleep frequency. When the timer runs out, the frequency converter will ramp down the motor to stop via parameter 208 Ramp-down time. If the output frequency rises above the frequency set in parameter 404 Sleep frequency, the timer is reset.

Description of choice:

Select AC brake [4] if short-term generated loads occur.

■Sleep mode

Sleep mode makes it possible to stop the motor when it is running at low speed, similar to a no load situation. If consumption in the system goes back up, the frequency converter will start the motor and supply the power required.

NB!:

Energy can be saved with this function, since the motor is only in operation when the system needs it.

Sleep mode is not active if Local refe ren ce or Jog has been selected The function is active in both Open loop and Closed loop.

While the frequency converter has stopped the motor in sleep mode, a theoretical output frequency is calculated on the basis of the reference signal. When the theoretical output frequency rises above the frequency in parameter 407 Wake up frequency, the frequency converter will restart the motor and the output frequency will ramp up to the reference.

In systems with constant pressure regulation, it is advantageous to provide extra pressure to the system before the frequency converter stops the motor. This extends the time during which the

VLT®FCM Series

frequency converter has stopped the motor and helps to avoid frequent starting and stopping of the motor, e.g. in the case of system leaks. If 25% more pressure is required before the frequency converter stops the motor, parameter 406 Boost setpoint is set to 125%. Parameter 406 Boost setpoint is only active in Closed loop.

NB!:

In highly dynamic pumping processes, it is recommended to switch off the Flying Start function (parameter 445).

■FCM 300 Regulator

rocess regulation

P The PID regulator maintains a constant process mode (pressure, temperature, flow, etc.) and adjusts the motor speed on the basis of the reference/setpoint and feedback signal. A transmitter provides the PID regulator with a feedback signal from the process as an expression of the process’s actual mode. The feedback signal varies as the process load varies. This means that there is a variance between the reference/setpoint and the actual process mode. This variance is compensated by the PID regulator by means of the output frequency being regulated up or down in relation to the variance between the reference/setpoint and the feedback signal.

The integrated PID regulator in the frequency converter has been optimised for use in process applications. This means that there are a number of special functions available in the frequency converter. Previously it was necessary to obtain a system to handle these special functions by installing extra I/O modules and programming the system. With the frequency converter the need to install extra modules can be avoided. The parameters that are specific to the Process Regulator are parameter 437 to parameter 444.

■PID functions

nit of reference/feedback

U When Process regulation, closed loop is selected

in parameter 100 Configuration the unit is defined in parameter 416 Reference/feedback unit:

eedback

F A feedback range must be preset for the regulator. At the same time this feedback range limits the potential reference range so that if the sum of all references lies outside the feedback range, the reference will be limited to lie within the feedback range. The feedback signal must be connected to a terminal on the frequency converter. If feedback is selected on two terminals simultaneously, the two signals will be added together. Use the overview below to determine which terminal is to be used and which parameters are to be programmed.

Feedback type Terminal Parameters

Pulse 3 333, 327

Voltage 2 332, 338, 339

Current 1 331, 336, 337

A correction can be made for loss of voltage in long signal cables when a transmitter with a voltage output is used. This is done in parameters 338/339 Min./Max s caling.

Parameters 414/415 Minimum/Maximum feedback must also be preset to a value in the process unit corresponding to the minimum and maximum scaling values for signals that are connected to the terminal.

eference

R In parameter 205 Maximum reference, Ref possible to preset a maximum reference that scales the sum of all references, i.e. the resulting reference. The minimum reference in parameter 204 is an expression of the minimum value that the resulting reference can assume. All references will be added together and the sum will be the reference against which regulation will take place. It is possible to limit the reference range to a range that is smaller than the feedback range. This can be an advantage if you want to avoid an unintentional change to an external reference making the sum of the references move too far away from the optimal reference. The reference range cannot exceed the feedback range. If preset references are desired, they are preset in parameters 215 to 216 Preset reference.See description Reference Function and Handling of References in parameter 214. If a current signal is used as the feedback signal, it will only be possible to use voltage as an analogue reference. Use the overview below to determine which terminal is to be used and which parameters are to be programmed.

NB!:

It is best to preset terminals that are not being used to No function [0].

ifferentiator gain limit

D If very rapid variations occur in an application in either the reference signal or the feedback signal, the deviation between the reference/setpoint and the process’s actual mode will change quickly. The differentiator can then become too dominant. This is because it is reacting to the deviation between the reference and the process’s actual mode, and the quicker the variance changes the more powerful the differentiator’s frequency contribution becomes. The differentiator’s frequency contribution can therefore be limited in such a way that both a reasonable differentiation time for slow changes and an appropriate frequency contribution for quick changes can be preset. This is done using parameter 443 Process PID Differentiator gain limit.

owpass filter

L If there is a lot of noise in the feedback signal, these can be dampened using an integrated lowpass filter. A suitable lowpass filter time constant is preset. If the lowpass filter is preset to 0.1 s, the cut-off frequency will be 10 RAD/sec, corresponding to (10 / 2 x π) = 1.6 Hz. This will mean that all currents/voltages that vary by more than 1.6 oscillations per second will be dampened. In other words, there will only be regulation on the basis of a feedback signal that varies by a frequency of less than 1.6 Hz. The appropriate time constant is selected in parameter 444 Process PID lowpass filter time.

VLT®FCM Series

nverse regulation

I Normal regulation means that the motor speed is increased when the reference/setpoint is greater than the feedback signal. If it is necessary to run inverse regulation, in which the speed is reduced when the reference/setpoint is greater than the feedback signal, parameter 437 PID normal/inverse control must be programmed at Inverted .

nti Windup

A In the factory the process regulator is preset with an active anti windup function. This function means that when either a frequency limit, a current limit or a voltage limit is reached, the integrator is initialised at a frequency corresponding to the present output frequency. This is a means of avoiding the integration of a variance between the reference and the process’s actual mode that cannot be deregulated by means of a change of speed. This function can be deselected in parameter 438 Process PID anti windup.

tarting conditions

S In some applications the optimal setting of the process regulator will mean that a relatively long period of time will pass before the required process condition is achieved. In these applications it can be a good idea to define an output frequency to which the frequency converter must run the motor before the process regulator is activated. This is done by programming a start frequency in parameter 439 Process PID start frequency.

■Handling of feedback

Feedback handling is depicted in this flowchart. The flowchart shows which parameters can affect the handling of feedback and how. A choice can be made between voltage, current and pulse feedback signals.

Value:

✭Normal (NORMAL)

Inverse (INVERSE)

Function:

It is possible to choose whether the process regulator is to increase/reduce the output frequency if there is a difference between the reference signal and the feedback signal. Used together with Process, closed loop mode (parameter 100).

Description of choice:

If the FC motor is to reduce the output frequency in case the feedback signal increases, select Normal [0]. If the FC motor is to increase the output frequency in case the feedback signal increases, select Inverse [1].

Description of choice:

The factory setting is Enable [1], which means that the integration link is adjusted in relation to the actual output frequency if either the current limit or the max./ min. frequency has been reached. The process regulator will not engage again until either the error is zero or its sign has changed.

Function:

When the start signal comes, the FC motor will react in the form of Speed, open loop mode following the ramp. Only when the programmed start frequency has been obtained, will it change over to Process, closed loop mode. In addition, it is possible to set a frequency that corresponds to the speed at which the process normally runs, which will enable the required process conditions to be reached sooner.

Used together with Process, closed loop mode (parameter 100).

Description of choice:

Set the required start frequency.

NB!:

If the FC motor is running at the current limit before the desired start frequency is obtained,

the process regulator will not be activated. For the regulator to be activated anyway, the start frequency must be lowered to the required output frequency. This can be done during operation.

[999900]

VLT®FCM Series

Function:

The integrator provides an increasing gain at a constant error between the set point and the feedback signal. The greater the error, the quicker the gain will increase. The integral time is the time needed by the integrator to reach the same gain as the proportional gain.

Used together with Process, closed loop mode (parameter 100).

Description of choice:

Quick regulation is obtained at a short integral time. However, this time may become too short, which can make the process unstable.

If the integral time is long, major deviations from the required set point may occur, since the process regulator will take a long time to regulate in relation to a given error.

442 Process PID differentiation time

(PROC. DIFF. TIME)

Value:

0.00 (OFF) - 10.00 sec.

✭0.00 sec.

Function:

The differentiator does not react to a constant error. It only provides a gain when the error changes. The quicker the error changes, the stronger the gain from the differentiator.

The gain is proportional to the speed at which the error changes.

Used together with Process, closed loop mode (parameter 100).

Description of choice:

Fast regulation is obtained with a long differentiation time. However, this time may become too long, which can make the process unstable.

[50]

[0]

The differentiator gain will increase if there are fast changes, which is why it can be beneficial to limit this gain, thereby obtaining a pure differentiator gain at slow changes and a constant differentiator gain where quick changes to the error occur.

Used together with Process, closed loop mode (parameter 100).

Description of choice:

Select a limit to differentiator gain as required.

444 Process PID lowpass filter time

(PROC. FILTER TIME)

Value:

0.02 - 10.00 sec

✭0.02 sec

Function:

Oscillations on the feedback signal are dampened by the lowpass filter in order to reduce their impact on the process regulation. This can be an advantage e.g. if there is a lot of noise on the signal.

Used together with Process, closed loop mode (parameter 100).

Description of choice:

Select the desired time constant (τ). Ifatimeconstant (τ) of 100 ms is programmed, the break frequency for the lowpass filter will be 1/0.1 = 10 RAD/sec., correspondingto(10/2xπ)=1.6Hz.

The process regulator will thus o signal that varies by a frequency lower than 1.6 Hz. If the feedback signal varies by a higher frequency than

1.6 Hz, the Process regulator will not react.

to be stopped using DC brake before the motor is ramped up to the desired speed. The DC brake time must be set in parameter 126.

Limitations:

1. Too low inertia will cause acceleration of the load,

which may be dangerous or prevent succesful Flying start. Use DC brake instead.

2. If load is driven eg. by "windmilling", the unit

might trip due to overvoltage.

This is used, e.g. where regulation of a flow (volume) is required on the basis of pressure as feedback signal (flow = constant x √pressure). This conversion makes it possible to set the reference in such a way that there is a linear connection between the reference and the flow required. See drawing.

■ Serial bus

■ Telegram communication

ontrol and reply telegrams

C The telegram communication in a master/slave system is controlled by the master. A maximum of 31 slaves (FC motors) can be connected to one master, unless a repeater is used - see also the description of the address format.

The master continuously sends control telegrams addressed to the slaves and awaits reply telegrams from these. The response time of the slaves is maximum 50 ms.

Only a slave that has received a faultless telegram addressed to that slave will respond by sending back the telegram unchanged.

roadcast

B A master can send the same telegram at the same time to all slaves connected to the bus. In such

broadcast communication, the control telegram broadcast bit of the address bit has a value of 1 (see

VLT address). Address bits 0-4 are not used.

ontents of a byte

C Each transmitted sign begins with a start bit. Subsequently, 8 databits are transmitted. Each sign is given via a parity bit set at "1" when there is an even parity (i.e. an even number of binary 1’sinthe8 databits and parity bits together). The sign ends with a stop bit and thus consists of a total of 11 bits.

■ Telegram build-up

Each telegram begins with a startbyte (STX) = 02 Hex, followed by a byte that gives the telegram length (LGE)

MG.03.H3.02 - VLT is a registered Danfoss trademark

VLT®FCM Series

and a byte that gives the address (ADR). Then follows a number of databytes (variable, depending on telegram type). The telegram ends with a data control byte (BCC).

Telegram length (LGE) The telegram length is the number of databytes plus address byte ADR plus data control byte BCC.

Telegrams with 4 databytes have a length of: LGE=4+1+1=6bytes Telegrams with 12 databytes have a length of: LGE=12+1+1=14bytes

LT address (ADR)

V Two different address formats are used:

1. Siemens USS protocol address format:

BCC

EXOR and gives a new BCC

OLD

NEW

, e.g.:

EXOR

second byte" = 1 1 0 1 0 1 1 0 (D6H)

" BCC

=11010100

NEW

The result after the last received sign is BCC.

■ Databytes

The block of databytes is divided into two smaller blocks:

1. Parameter bytes used for transferred parameters

between master and slave

2. Process bytes, covering

- Control word and reference value (from master to slave)

- Status word and present output frequency (from slave to master)

This structure applies to both the control telegram (master → slave) and the reply telegram (slave → master).

Bit 7 = 0 Bit6isnotused Bit 5 = 1: Broadcast, address bits (0-4) are not used Bit 5 = 0: No Broadcast Bits0-4=VLTaddress1-31

2. Danfoss format:

Bit 7 = 1 Bits 0-6 = VLT address 1-127 (0 = Broadcast)

ata control byte (BCC)

D The data control byte can best be explained by means of an example: Before the first sign of the telegram is received, BCC = 0.

After the first sign has been received: BCC

Each additional, subsequent byte is gated by

There are two types of telegrams:

- with 12 bytes built up as shown above, with

parameter and process block

- with four bytes, which is the process block

from the 12 byte telegram

. Parameter bytes

Commands and replies (AK) Bits no. 12-15 are used for transmitting commands from master to slave and the slave’s processed reply back to the master.

Bits no. 0-10 are used for transmitting parameter numbers. The function of a given parameter can be seen from the parameter description in chapter 8.

Index Index is used together with the parameter number for read/write access to parameters of the array type (par. 615, 616 and 617).

arameter value (PWE)

The parameter value depends on the command given. If the master wants a parameter (read), it does not care about the PWE block value. If a parameter is changed by the master (write), the new value is transferred in the PWE block. If the slave replies to a parameter request (read command), the present parameter value is transferred to the PWE block.

If the command cannot be executed, the slave will send this reply (0111) and give the following error message in the parameter value:

Error code

(reply 0111) Error message

0 The parameter number used does not

1 There is no write access to the

can only be changed when the motor

has stopped

130 There is no bus access to the

parameter called

131 Data change is not possible because

factory Setup has been selected

Parameter number (PNU)

The transferred value corresponds to the figures given in the parameter descriptions in chapter 8. E.g. parameter 101, where [1] corresponds to Constant torque, [2] corresponds to Variable torque: low,etc. However, parameters with data type 9 (text string) are excepted, as this text is transferred as an ASCII text string. When a text string is transferred (read), the telegram length is variable, since the texts have different lengths. The telegram length is stated in the 2nd byte of the telegram, called LGE, see page 73. Parameters 621-634 (nameplate data) have data type 9 (text string).

ata types supported by the VLT frequency converter

Data type Description

3Integer16 4Integer32 5 Unsigned 8 6 Unsigned 16 7 Unsigned 32 9Textstring

Unsigned means there is no sign included in the telegram.

The different attributes for each parameter can be seen in the section on factory settings. Since a parameter value can only be transferred as an integer, aconversionfactormustbeusedtotransferdecimals.

MG.03.H3.02 - VLT is a registered Danfoss trademark

VLT®FCM Series

Example: Parameter 201: minimum frequency, conversion factor 0,1. If parameter 201 is to be set to 10 Hz, a value of 100 must be transferred, since a conversion factor of 0,1 means that the transferred value will be multiplied by 0.1. A value of 100 will thus be understood as 10.

ddressing by unit ID

2. Process-bytes The process byte block is divided into two blocks each of 16 bits, which always come in the sequence stated.

■Controlwordaccording to FieldbusProfileStandard

(parameter 512 = Fieldbus Profile) The control word is used for transmitting commands from a master (e.g. a PC) to a slave (FC motor).

The unit ID is printed on the label on the plastic cover under the lid of the electronics box. The three groups of unit ID each with three digits must be converted to Hex. The desired address is added as the last byte. The frame is sent to the bus address parameter(s) 500 (and 918) via a broadcast.

Quick-stop which uses the ramp time in parameter

212. Bit 04 = "0" leads to a quick-stop. Bit 04 = "1" means that the frequency converter is able to start, provided the other conditions for starting are fulfilled. Note: In parameter 503 the choice is made as to how bit 04 is to be combined (gated) with the corresponding function on the digital inputs.

it 05, Freeze output frequency/ramp enable:

B Bit 05 = "0" means that the given output frequency is maintained even if the reference is changed. Bit 05 = "1" means that the frequency converter is again able to regulate, and the given reference is followed.

it 06, Ramp stop/start:

B An ordinary ramp stop that uses the ramp time in parameters 207/208. Bit 06 = "0" leads to a stop. Bit 06 = "1" means that the frequency converter is able to start, provided the other conditions for starting have been fulfilled.

B Activation of pre-programmed speed in parameter 509 (Bus JOG 1). JOG 1 is only possible when Bit 04 = "0" and bit 00-03 = "1".

it 09, Jog 2 OFF/ON:

B Activation of pre-programmed speed in parameter 510 (Bus JOG 2). JOG 2 is only possible when Bit 04 = "0" and Bits 00-03 = "1". If both JOG 1 and JOG 2 are activated (Bits 08 and 09 = "1"), JOG 1 has the higher priority, which means that the speed programmed in parameter 509 will be used.

it 10, Data not valid/valid:

B Used for telling the FC motor whether the control word is to be used or ignored. Bit 10 = "0" means that the control word is ignored. Bit 10 = "1" means that the control word is used. This function is relevant because the control word is always contained in the telegram, regardless of the type of telegram used, i.e. it is possible to disconnect the control word if it is not to be used in connection with updating or reading of parameters.

it 12, No function / catchup, relay 123:

B Used for increasing the speed reference by the value of parameter 219. Bit 12 = "0" means that there is no change of the reference; Bit 12 = "1" means that the reference is increased. If both slow down and catchup are activated (Bits 11 and 12 = "1"), slow down has the higher priority, i.e. the speed reference is reduced. Bit 12 = "1" will also activate relay 123 (provided parameter 323 = "Control word bit 12").

its 13, Choice of Setup:

B Bit 13 is used for choosing between the two menu Setups in accordance with the following table:

Setup Bit 13 10 21

This function is only possible if Multi-Setups have been selected in parameter 004.

NB!:

Parameter 507 is used for choosing how Bit 13 is to be combined (gated) with the corresponding function on the digital inputs.

it 15, No function/reversing:

B Reversing of the direction of rotation of the motor. Bit 15 = "0" leads to no reversing, Bit 15 = "1" leads to reversing.

NB!:

Unless otherwise mentioned, the control word bit is combined (gated) with the corresponding function on the digital

inputs as a logic "or" function.

■ Galvanic isolation (PELV)

PELV offers protection by way of extra low voltage. Protection against electric shock is considered to be ensured when all connected devices are of the PELV type and the installation is made as described in local/national regulations on PELV supplies.

In FCM 300 Series all control terminals are supplied from or in connection with extra low voltage (PELV).

Galvanic (ensured) isolation is obtained by fulfilling requirements concerning higher isolation and by providing the relevant creapage/clearance distances. These requirements are described in the EN 50178 standard.

The components that make up the electrical isolation, as described below, also comply with the requirements concerning higher isolation and the relevant test as described in EN 50178.

The galvanic isolation can be shown in three locations (see drawing below), namely:

1. Power supply (SMPS) incl. signal isolation of U

indicating the intermediate current voltage.

2. Gate drive that runs the IGBTs (optocouplers).

3. Current transducers (opto-couplers).

■ Earth leakage current

Earth leakage current is primarily caused by the capacitance between motor phases and the motor frame. The RFI filter contributes additional leakage current, as the filter circuit is connected to earth through capacitors.

The size of the leakage current to the ground depends on the following factors, in order of priority:

1. Switching frequency

2. Motor grounded on site or not

The leakage current is of importance to safety during handling/operation of the frequency converter if (by mistake) the frequency converter has not been earthed.

NB!:

FCM 305-375 all have leakage currents > 3.5 mA,approx4to20mA.Varieswithswitching frequencies within the given interval.

This means reinforced earthing mus be established (see Quick Guide MG.03.A1.02), if EN50178 is to be complied with. Never use ELCB (Earth Leakage Circuit Breaker) relays also called RCD(Residual Current Device) that are not suitable for DC fault currents (type A).

If a RCD is used it must be:

- Suitable for protecting equipment with a DC current content in the fault current (3-phase rectifier)

- Suitable for power-up with short charging

current to earth

- Suitable for a high leakage current.

ThismeansitispossibletooperatetheFCM 300 on RCD type B: Residual Current Devices (RCD) type B has a tolerance on trip level. It is therefore recommended to use a RCD where the max leakage current for the FCM (see above, 20 mA) is less than 1/3 of the trip level for the RCD. This means the trip level for the RCD will have to be 60 mA or higher, i.e. a RCD type B with a trip level 100 mA can be used for protection.

All about FCM

The voltage in the intermediate circuit is increased when the motor acts as a generator. This occurs in two cases:

1. The load drives the motor (at constant output frequency from the frequency converter), i.e. the load generates energy.

2. During deceleration ("ramp-down") if the moment of inertia is high, the load is low and the ramp-down time is too short for the energy to be dissipated as a loss in the VLT frequency converter, the motor and the installation.

The control unit attempts to correct the ramp if possible.

The inverter turns off to protect the transistors and the intermediate circuit capacitors when a certain voltage level is reached.

ains drop-out

M During a mains drop-out, FCM 300 Series continues until the intermediate circuit voltage drops below the minimum stop level, which is typically 15% below FCM 300 Series’s lowest rated supply voltage.

The time before the inverter stops depends on the mains voltage before the drop-out and on the motor load.

VLT®FCM Series

tatic overload

S When FCM 300 Series is overloaded (the current limit in parameter 221 has been reached), the controls will reduce the output frequency in an attempt to reduce the load.

If the overload is excessive, a current may occur that makes the FC motor cut out after approx. 1.5 sec.

■ Derating for running at low speed

When a centrifugal pump or a fan is controlled by a FC motor, it is not necessary to reduce the output at low speed because the load characterstic of the centrifugal pumps/fans, automatically ensures the necessary reduction.

FC motors running constant load torque applications continuously at low speed must be derated (see diagram) or an independent fan must be used (cooling option 2, not yet available).

Nominal torque (100%) can be yielded up to 15 min and at a duty cycle up to 25% at low speed.

All about FCM

■ Derating for high switching frequency

The FCM 300 Series motor can use two different PWM schemes, SFAVM and 60° AVM. Factory setting is SFAVM. The PWM scheme can be changed in

MG.03.H3.02 - VLT is a registered Danfoss trademark

parameter 446. Below 25 Hz motor speed the FCM 300 Series motor automatically change to SFAVM.

Factory setting of the switching frequency is 4000 Hz. It can be changed between 2 and 14 kHz in parameter 411.

A higher switching frequency leads to a quieter running unit but higher losses in the electronics of the FC motor and makes an appropriate derating necessary.

■ Mains supply interference/harmonics

A FC motor takes up a non-sinusoidal current from mains, which increases the input current I

RMS

.A nonsinusoidal current can be transformed by means of a Fourier analysis and split up into sine wave currents with different frequencies, i.e. different harmonic currents I

Harmonic

with 50 Hz as the basic frequency:

currents Hz 50 Hz 250 Hz 350 Hz 550 Hz In/I1 [%] 100% 44% 29% 8%

The harmonics do not affect the power consumption directly, but increase the heat losses in the installation (transformer, cables). Consequently, in plants with a rather high percentage of rectifier load, it is important to maintain harmonic currents at a low level to avoid overload of the transformer and high temperature in the cables.

MG.03.H3.02 - VLT is a registered Danfoss trademark

VLT®FCM Series

Some of the harmonic currents might disturb communication equipment connected to the same transformer or cause resonance in connection with power-factor correction batteries.

To ensure low, harmonic currents, FCM 300 has intermediate circuit coils as standard.. THD (current) ≤ 54% The voltage distortion on the mains supply depends on the size of the harmonic currents multiplied by the mains impedance for the frequency in question. The total voltage distortion THD is calculated on the basis of the individual voltage harmonics using the following formula:

and I

■The machinery directive(98/37/EEC)

All machines with critical moving parts are covered by the machinery directive, which came into force on 1 January 1995. Since a frequency converter is largely electrical, and the motor always will be placed in connection with other machines, it does not fall under the machinery directive. However, if a FC motor is supplied for use in a machine, we provide information on safety aspects relating to the FC motor. We do this by means of a manufacturer’s declaration.

■The low-voltage directive (73/23/EEC)

Frequency converters must be CE labelled in accordance with the low-voltage directive. The directive applies to all electrical equipment and appliances used in the voltage range of 50-1000 V AC and 75-1500 V DC.

■The EMC directive(89/336/EEC)

EMC is short for electromagnetic compatibility. The presence of electromagnetic compatibility means that the mutual interference between different components/ appliances is so small that the functioning of the appliances is not affected. The

EMC directive came into force on 1 January 1996. The directive distinguishes between components, appliances, systems and installations.

The power factor indicates the extent to which the FC motor imposes a load on the mains supply.

The lower the power factor, the higher the I

RMS

for the same kW performance.

In addition, a high power factor indicates that the different harmonic currents are low.

■What is CE labelling?

The purpose of CE labellingis to avoid technical obstacles to trade within EFTA and the EU. The EU has introduced the CE label as a simple way of showing whether a product complies with the relevant EU directives. The CE label says nothing about the specifications or quality of the product. Frequency converters are regulated by three EU directives:

■What is covered?

The EU "Guidelines on the Application of Council Directive 89/336/EEC" outline three typical situations of using a FC motor. For each of these situations, explanations are offered as to whether the situation in question is covered by the EMC directive and must be CE labelled.

1. The FC motor is sold directly to the endconsumer.

The FC motor is for example sold to a DIY market. The end-consumer is a layman. He installs the FC motor himself for use with a hobby machine, a kitchen appliance, etc. For such applications, the FC motor must be CE labelled in accordance with the EMC directive.

2. The FC motor is sold for installation in a plant. The

plant is built up by professionals of the trade. It could be a production plant or a heating/ ventilation plant designed and installed by professionals of the trade. Neither the FC motor nor the finished plant has to be CE labelled under the EMC directive. However, the unit must comply with the basic EMC requirements of the directive. The installer can ensure this by using components, appliances and systems that are CE labelled under the EMC directive.

300

All about FCM

MG.03.H3.02 - VLT is a registered Danfoss trademark

VLT®FCM Series

3. The FC motor is sold as part of a complete system. The system is being marketed as complete. It could be e.g. an air-conditioning system. The complete system must be CE labelled in accordance with the EMC directive. The manufacturer who supplies the system can ensure CE labelling under the EMC directive either by using CE labelled components or by testing the EMC of the system. If he chooses to use only CE labelled components, he does not have to test the entire system.

■Danfoss FCM 300 Series motor and CE labelling

CE labelling isa positive feature when used for its original purpose, i.e. to facilitate trade within the EU and EFTA.

However, CE labelling may cover many different specifications. This means that it has to be checked what a given CE label specifically covers.

The specifications covered can in fact be widely different. That is why a CE label can give the installer a false feeling of security when using a FC motor as a component in a system or an appliance.

We CE label our VLT

DriveMotors in accordance with the low-voltage directive. This means that as long as the FC motor is installed correctly, we guarantee that it complies with the low-voltage directive. We issue a declaration of conformity that confirms our CE labelling in accordance with the low-voltage directive.

The CE label also applies to the EMC directive, on condition that the instructions given in the Operating Instructions for EMC-correct installation and filtering have been followed. On this basis, a declaration of conformity in accordance with theEMCdirectiveisissued.

The Quick Guide gives detailed instructions for installation to ensure that your installation is EMCcorrect. Furthermore, we specify which norms that are complied with by our different products.

We offer the filters that can be seen from the specifications and gladly provide other types of assistance that can help you obtain the best EMC result.

■ Compliance with EMC directive 89/336/EEC

In the great majority of cases, the VLT DriveMotor is used by professionals of the trade as a complex component forming part of a larger appliance, system or installation. It must be noted that the responsibility for the final EMC properties of the appliance, system or installation rests with the installer. As an aid to the installer, Danfoss has prepared EMC installation guidelines for the Power Drive System. The standards and test levels stated for Power Drive Systems are complied with, provided the right

EMC-correct instructions for installation have been followed, see electrical installation.

eneral aspects of EMC emissions

G For high frequency shielding, screened cables used for Profibus, standard bus, control cables and signal interface must in general be connected to the enclosure at both ends.

eneral aspects of EMC immunity

G If there are problems with low frequency interference (ground loops), screened cable used for Profibus, standard bus, control cables and signal interface can be left open at one end.

■ Aggressive environments

In common with all electronic equipment, a VLT frequency converter contains a large number of mechanical and electronic components, all of which are vulnerable to environmental effects to some extent.

The VLT frequency converter should not therefore be installed in environments with

airborne liquids, particles or gases capable of affecting and damaging the electronic components. Failure to take the necessary protective measures increases the risk of stoppages, thus reducing the life of the VLT frequency converter.

Liquids can be carried through the air and condense in the VLT frequency converter. In addition to this, liquids may cause corrosion of components and metal parts. Steam, oil and salt water may cause corrosion of components and metal parts. In such environments, equipment with enclosure rating ≥ IP 54 is recommended.

In environments with high temperatures and humidity,

orrosive gases such as sulphur, nitrogen and

c chlorine compounds will cause chemical processes on the VLT frequency converter components. Such chemical reactions will rapidly affect and damage the electronic components.

NB!:

Mounting VLT frequency converters in aggressive environments will increase the risk of stoppages and furthermore considerably

reduce the life of the converter.

Before the installation of the VLT frequency converter, the ambient air should be checked for liquids, particles and gases. This may be done by observing existing installations in this environment. Typical indicators of harmful airborne liquids are water or oil on metal parts, or corrosion of metal parts.

Excessive dust particle levels are often found on installation cabinets and existing electrical installations. One indicator of aggressive airborne gases is blackening of copper rails and cable ends on existing installations.

Alarm, this can mean that a warning precedes the alarm. It can also mean that it is possible to program whether a given fault is to result in a warning or an alarm. After a trip, alarm and warning will flash, but if the fault is removed, only alarm will flash. After a reset, the FC motor will be ready to start operation again.

■What if the motor does not start?

The LCP may be set for local stop. If so, the motor does not start when you disconnect the LCP. To make the motor start a LCP has to be connected, - there is no other way, and the VLT Dialog Software will not

tell you what is wrong og what to do. So in case of problems follow the procedure stated below:

Warning: Extreme care must be taken when operating the unit with open lid.

Green Yellow Red Action LED 302 LED 301 LED 300 OFF OFF OFF Apply power ON OFF OFF Apply start and reference signals , (see drawing on page 17) ON OFF ON Apply and remove reset signal according to the drawing on page 17. ON ON ON Switch off power until all LED’s have turned off For further information see the quick setup MG.03.Fx.xx.

1. Make sure no parameters have been changed from initial delivery status (factory setting). Use the Local Control Panel or serial port to reset to factory setting. Make sure that parameter 002 is set for remote (if not, the yellow LED 301 will be flashing slowly.

2. Make sure no STOP command has been made via the optional control panel keyboard (local stop, yellow LED 301 flashing slowly *), Control panel STOP can only be restarted by the Control Panel START button.

3. Check the Light Emitting Diodes visible through a hole in the inside isolation cover (see drawing page 16) follow table below.
