Safety

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

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).

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 (ELCB relays) is described 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,

these 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.

FCM 300 Series

MG.03.B6.02 - VL T is a register ed Danfoss trademark8

Product concept

■ 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 wider or longer than the motor (see chapter 6).

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.

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.

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.

■ 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.

Fitting 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.

Mechanical specifications

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.

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

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

(d) The FC-motor should be re-assembled in the

reverse order from dismantling, remembering to ease endshields onto bearings and spigots. DO NOT USE FORCE.

(e) Before starting, check that the rotor revolves

freely . Ensur e that the electrical connections ar e correct.

(f) Refit any pulley , coupling, spr ocket etc. which

has been removed, being particularly careful to ensure correct alignment with the driven part, as misalignment will lead to ultimate bearing trouble and shaft breakage.

(g) When replacing screws and bolts, care should

be taken to use only those with the requisite quality and tensile strength recommended by the manufacturer. These must also be of identical thread form and screw/bolt length (see the table above).

■ Forced ventilation (FV) units

In some applications the fan built on to the motor shaft do not give sufficient cooling for operation at low speed (see drawing on page 84). That problem is solved by mounting a FV unit.

Typical applications are for example conveyors, spindles and other contant torque (CT) applications where the customer wants a wide control range down to low speed.

The FV unit is available in 2 versions. The characteristics of the two versions are the same. The variable factors are the length and the placing of the terminal box.

The VLT Drive Motor yields full continuous torque down to low speed with FV built on.

The LCP 2 is connected to the terminal X100, 1-4 (see separate instruction MI.03.AX.YY).

■■

■ LCP functions

The functions of the control panel can be divided into three groups:

● display

● keys for changing program parameters

● keys for local operation

All data are indicated by means of a 4-line alphanumeric display, which in normal operation is able to show 4 measurements and 3 operating conditions continuously. During programming, all the information required for quick, effective parameter

3rd line is normally blank and is used in the menu mode to show the selected parameter number or parameter group number and name.

4th line is used in operating status for showing a status text or in data change mode for showing the value of the selected parameter.

An arrow indicates the direction of rotation of the motor. Furthermore, the Setup which has been selected as the Active Setup in parameter 004 is shown. When programming another Setup than the Active Setup, the

number of the Setup which is being programmed will appear to the right. This second Setup number will flash.

■■

■ LEDs

At the bottom of the control panel is a red alarm LED and a yellow warning LED, as well as a green voltage LED.

■ Control keys

The control keys are divided into functions. This means that the keys between display and indicator LEDs are used for parameter Setup, including choice of display indication during normal operation.

Keys for local control are found under the indicator LEDs.

■ Control key functions

[DISPLAY / STATUS] is used for selecting the mode of display or for changing back to Display mode from either the Quick menu mode or the Menu mode.

[QUICK MENU] is used for programming the parameters that belong under the Quick menu mode. It is possible to switch directly between Quick menu mode and Menu mode.

[MENU] is used for programming all parameters. It is possible to switch directly between Menu mode and Quick menu mode.

[CHANGE DATA] is used for changing the parameter selected either in the Menu mode or the Quick menu mode.

[CANCEL] is used if a change of the selected parameter is not to be carried out.

[OK] is used for confirming a change of the parameter selected.

[+/-] is used for selecting parameter and for changing the chosen parameter or for changing the read out in line 2.

[<>] is used for selecting group and to move the cursor when changing numerical parameters.

[STOP / RESET] is used for stopping or for resetting the FC motor after a drop-out (trip). Can be selected via parameter 014 to be active or inactive. If stop is activated, line 2 will flash, and [START] must be activated.

NB!

Pressing [STOP/RESET] will prevent motor

from running also with disconnected LCP 2. Restarting is only possible via the LCP 2 [START] key.

[JOG] overrides the output frequency to a preset frequency while the key is kept down. Can be selected via parameter 015 to be active or inactive.

[FWD / REV] changes the direction of rotation of the motor, which is indicated by means of the arrow on the display although only in Local. Can be selected via parameter 016 to be active or inactive (parameter 013 must be set to [1] or [3] and parameter 200 set to [1].

[START] is used for starting the FC motor a fter stop vi a the [Stop] key. Is always active, but cannot override a stop command given via the terminal strip.

If certain threshold values are exceeded, the alarm and/or warning lamp lights up together with a status and alarm text on the control panel. The voltage LED is activated when the FC motor receives voltage; at the same time the rear lighting of the display will be on.

■ Display read-out state

The display read-out state can be varied - see the list on page 32 - depending on whether the FC motor is in normal operation or is being programmed.

■ Display mode

In normal operation, up to 4 different operating variables can be indicated continuously: 1,1 and 1,2 and 1,3 and 2, and in line 4 the present operating status or alarms and warnings that have arisen.

■ Display mode - selection of read-out state

There are three options in connection with the choice of read-out state in the Display mode - I, II and III. The choice of read-out state determines the number of operating variables read out.

STATUS

VAR 2

VAR 1.1 VAR 1.2 VAR 1.3

Operating variables 1,1 and 1,2 and 1,3 in the first line, and operating variable 2 in the second line are selected via parameter 009, 010, 011 and 012.

• Read-out state I: This read-out state is standard after starting up or after initialisation.

Line 2 gives the data value of an operating variable with related unit, and line 1 provides a text which explains line 2, cf. table. In the example, Frequency has been selected as variable via parameter 009. During normal operation another variable can immediately be read out by using the [+/-] keys.

NB!

If the keys for local control have been selected as active, they will remain active

both when the frequency has been set for Local Control and for Remote Control via parameter 002, although with the exception of [FWD/REV], which is only active in Local operation.

NB!

If no external stop function has been selected

and the [STOP] key has been selected as inactive via parameter 014, the FC motor can be started and can only be stopped by disconnecting the voltage to the motor.

■ 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:

At the bottom of the display, the parameter number and name are given together with the status/value of the first parameter under Quick Setup. The first time the [Quick Menu] key is pressed after the unit has been switched on, the read-outs will always start at pos. 1 - see table below.

■ Parameter selection

The selection of parameter is effected by means of the [+/-] keys. The following parameters are accessible:

Pos.:No.: Parameter: Unit: 1 001 Language 2 200 Direction of rotation 3 101 Torque characteristic 4 204 Min. reference [Hz] 5 205 Max. reference [Hz] 6 207 Ramp up time [sec.] 7 208 Ramp down time [sec.] 8 002 Local/remote control 9 003 Local reference 10 500 Bus address

• Read-out state III: This read-out state can be held as long as the [DISPLAY/STATUS] key is pressed. When the key is released, the system switches back to Read-out state II, unless the key is pressed for less than approx. 1 sec..

This is where parameter names and units for operating variables in the first line are given operating variable 2 remains unchanged.

■ 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's option. 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 menu mode.

• Read-out state II: Switching between read-out states I and II is effected by pressing the [DISPLAY / STATUS] key.

In this state, data values for four operating values are shown at the same time, giving the related unit, cf. table. In the example, Reference, Torque, Current and Frequency are selected as variables in the first and second line.

■ Changing data

Regardless of whether a parameter has been selected under the Quick menu or the Menu mode, the procedure for changing data is the same. Pressing the [CHANGE DATA] key gives access to changing the selected parameter, following which the underlining in line 4 will flash on the display. The procedure for changing data depends on whether the selected parameter represents a numerical data value or a text value.

■ Changing a text value

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.

StartStart

Start, is selected if a start/stop command is desired.

Logic '1' = start, logic '0' = stop (stand-by).

Latched start Latched start

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.

ReversingReversing

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 reversingStart reversing

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

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:

This parameter makes it possible to select the reset function desired after tripping.

After reset, the FC motor can be restarted after 1.5 sec.

Description of choice:

If Manual reset [0] is selected, reset must be effected via the digital inputs.

If the FC motor is to carry out an automatic reset (max. 1-10 times within 10 minutes) after tripping, select data value [1]-[10].

Warning: The motor may start without warning up to 10 x 5 sec. after trip.

411 Switching frequency (SWITCH FREQ.)

Settings:

1.5 -14.0 kHz [1500 - 14000]

★ Unit dependent

Function:

The setting determines the switching frequency of the inverter. If the switching frequency is changed, this may help to minimise possible acoustic noise from the motor.

Description of choice:

When the motor is running, the switching frequency is adjusted in parameter 411 until the frequency has been obtained at which the motor is as low-noise as possible. See also parameter 446 - switching pattern. See derating in chapter 10.

NB!

Switching frequencies higher than 4 kHz may cause thermal trip depending on ambient

Settings:

★ Normal (NORMAL) [0]

Inverse (INVERSE) [1]

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].

438 Process PID anti windup

(PROC ANTI WINDUP)

Settings:

Disable (DISABLE) [0]

★ Enable (ENABLE) [1]

Function:

It is possible to select whether the process regulator is to continue regulating on an error even if it is not possible to increase/reduce the output frequency. Used together with Process, closed loop mode (parameter 100).

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.

Select Disable [0] if the integrator is to continue integrating on an error, even if it is not possible to remove the fault by such regulation.

NB!NB!

NB! If Disable [0] is selected, it will mean that when

the error changes its sign, the integrator will first have to integrate down from the level obtained as a result of the former error, before any change to the output frequency occurs.

439 Process PID start frequency

✭ parameter 201

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!NB!

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.

440 Process PID proportional gain

(PROC. PROP. GAIN)

Settings:

0.00 (OFF) - 10.00 [0 - 1000]

✭ 0.01 [1]

Function:

The proportional gain indicates the number of times the error between the set point and the feedback signal is to be applied.

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

Description of choice:

Quick regulation is obtained by a high gain, but if the gain is too high, the process may become unstable.

441 Process PID integral time

(PROC. INTEGR. T.)

Settings:

0.01 - 9999 sec. (OFF) [1 - 999900]

✭ 9999 sec. [999900]

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)

Settings:

0.00 (OFF) - 10.00 sec. [0 - 1000]

✭ 0.00 sec. [0]

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.

443 Process PID diff. gain limit

(PROC. DIFF. GAIN)

Settings:

5.0 - 50.0 [50 - 500]

✭ 5.0 [50]

Function:

It is possible to set a limit for the differentiator gain.

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).

444 Process PID lowpass filter time

(PROC. FILTER TIME)

Settings:

0.01 - 10.00 sec [1 - 1000]

✭ 0.01 sec [1]

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). If a time constant (τ) of 100 ms is programmed, the break frequency for the lowpass filter will be 1/0.1 = 10 RAD/sec., corresponding to (10/2 x π) = 1.6 Hz.

The process regulator will thus

only regulate a feedback 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.

Settings:

★ Disable (DISABLE) [0]

OK - same direction (OK-SAME DIRECTION) [1] OK - both directions (OK-BOTH DIRECTIONS) [2] DC-brake before start (DC-BRAKE BEF. START) [3]

Function:

This function makes it possible to ‘catch‘ a motor, which is spinning freely because of a mains dropout.

Description of choice:

Select Disable if this function is not required.

OK - same direction: Chosen if the motor can only

rotate in same direction on cut-in.

OK - both directions: Chosen if the motor can rotate in both directions on cut-in.

DC-brake - before start: Selected if the motor is 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.

3. Below 250 rpm the Flying start will not function.

✭ 1 [1]

Function:

This parameter allows specification of the address of each FC motor. This feature is used in connection with PLC/PC connection.

Description of choice:

The individual FC motor can be given an address between 1 and 126. The address 0 is used if a master (PLC or PC) wishes to send a telegram that is to be received by all FC motors connected to the serial communication port at the same time. In this case, the FC motor will not acknowledge receipt. If the number of units connected (FC motors + master) exceeds 31, a repeater is required.

■ Danfoss PC software for serial communication

Using serial communication makes it possible to monitor, programme and control one or several FC motors from a centrally placed computer. All FCM 300 Series have an RS 485 port as standard, which enables them to communicate e.g. with a PC. A programme entitled VLT

Software Dialog is available

for this purpose.

VLT

Software Dialog comes in three modules and as a minimum - contains the programmes included in the Basic module.

The Basic module covers:

TEST RUN is used for controlling and commissioning of a FC motor, including:

- setting of reference value,

- simultaneous display of selected parameters in graphs,

- option of DDE link, e.g. to a spreadsheet.

PARAMETER SETUP is used for setting up and transferring parameter sets, including:

- setting of FC motor parameters,

- parameter sets can be obtained from and copied to a FC motor,

- documentation/print-out of the Setup including diagrams.

BUS ADDRESS SETUP is used for setting the bus addresses on individual FC motors which are connected to the same bus.

- setting bus addresses

- storing list of units

- reporting list of units

The Logging module covers:

LOGGING is used for collecting and displaying historical or real-time operating data:

- graphical representation of selected parameters from several FC motors,

- collection of log data to file,

- option of DDE link e.g. to a spreadsheet.

MODEM SETUP is used for setting up the modem.

- sets the FC motor modem via the communication port of the PC.

The template module covers:

TEMPLATE SETUP is used for setting up template files for PARAMETER SETUP:

- the template file functions as a mask that limits the number of accessible parameters when a parameter file is to be made or edited in PARAMETER SETUP,

- the template file may contain preset values for the parameters of the FC motor.

NB!

The logging and template module calls for a Basic module to be installed on the same PC.

The guided tour covers:

GUIDED TOUR offers a demonstration of the VLT Software Dialog programme.

■ Telegram build-up

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

Control and reply telegrams 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.

Broadcast 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.

Contents of a byte 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's in the 8 databits and parity bits together). The sign ends with a stop bit and thus consists of a total of 11 bits.

Start 0 1 2 3 4 5 6 7 Even Stop

bit Parity bit

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

Serial communication

FCM 300 Series

MG.03.B6.02 - VL T is a register ed Danfoss trademark76

VLT address (ADR) Two different address formats are used:

1. Siemens USS protocol address format:

76543210 00

Bit 7 = 0 Bit 6 is not used Bit 5 = 1: Broadcast, address bits (0-4) ar e not used Bit 5 = 0: No Broadcast Bits 0-4 = VLT address 1-31

2. Danfoss format:

76543210 11

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

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

76543210

BCC

After the first sign has been received: BCC

NEW

= BCC

OLD

EXOR "first byte"

(EXOR = exclusive-or gate)

BCC

OLD

= 0 0 0 0 0 0 0 0 EXOR

"first byte" = 0 0 0 0 0 0 1 0 (02H) BCC

NEW

= 0 0 0 0 0 0 1 0 Each additional, subsequent byte is gated by BCC

OLD

EXOR and gives a new BCC

NEW

, e.g.:

BCC

OLD

= 0 0 0 0 0 0 1 0

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

BCC

NEW

= 1 1 0 1 0 1 0 0

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).

Parameter number (PNU) 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).

Parameter 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.

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).

Bit 00, OFF1/ON1: An ordinary ramp stop which uses the ramp time in parameters 207/208. Bit 00 = "0" leads to a stop and to output bei ng activated, the output frequency is 0 Hz, provided OFF 123 has been selected in parameter 340. Bit 00 = "1" means that the frequency converter will be able to start if the other conditions for starting have been fulfilled.

Bit 01, OFF2/ON2: Coasting stop. Bit 01 = "0" leads to a coasting stop and leads to output being activated, when the output frequency is 0 Hz, provided OFF 123 has been selected in parameter 340. Bit 01 = "1" means that the frequency converter is able to start, provided the other conditions for starting are fulfilled.

Bit 02, OFF3/ON3: Quick-stop, which uses the ramp time in parameter

212. Bit 02 = "0" leads to a quick-stop and leads to output being activated, when the output frequency is 0 Hz, provided OFF 123 has been selected in parameter 340. Bit 02 = "1" means that the frequency converter is able to start, provided the other conditions for starting are fulfilled.

Bit 03, Coasting/enable: Coasting. Bit 03 = "0" leads to a stop. Bit 03 = "1" means that the frequency converter is able to start, provided the other conditions for starting are fulfilled. Note: In parameter 502 the choice is made as to how bit 03 is to be combined (gated) with the corresponding function in the digital inputs.

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, a conversion factor must be used to transfer decimals.

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.

Addressing by unit ID 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.

Bit 07, No function/reset Reset of trip. Bit 07 = "0" means that there is no reset. Bit 07 = "1" means that a trip is reset. After reset it will take approx. 1.5 second until the unit is ready. The status word will indicate the ready state.

Bit 08, Jog 1 OFF/ON: 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".

Bit 09, Jog 2 OFF/ON: 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.

Bit 10, Data not valid/valid: 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.

Bit 11, No function/slow down: Used for reducing the speed reference by the value in parameter 219. Bit 11 = "0" means that there is no change of the reference. Bit 11 = "1" means that the reference is reduced.

Bit 12, No function/catch-up: 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.

Bits 13, Choice of Setup: 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!

corresponding function on the digital inputs.

Bit 15, No function/reversing: 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.

Bit 04, Quick-stop/ramp: 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.

Bit 05, Freeze output frequency/ramp enable: 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.

Bit 06, Ramp stop/start: An ordinary ramp stop that uses the ramp time in parameters 207/208; in addition, output will be activated when the output frequency is 0 Hz, provided OFF 123 has been selected in parameter

340. 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 are fulfilled. Note: In parameter 505 the choice is made as to how bit 06 is to be combined (gated) with the corresponding function on the digital inputs.

FCM 300 Series

■ 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 (opto-couplers).

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!

Since the leakage current is > 3.5 mA (approx. 4-20 mA), reinforced earthing must

be established (see Quick Guide MG.03.A1.02), which is required if EN 50178 is to be complied with. Never use ELCB relays that are not suitable for DC fault currents (type A).

If ELCB relays are used, they must be:

- Suitable for protecting equipment with a direct

current content (DC) in the fault current (3-phase bridge rectifier)

- Suitable for power-up with short charging

current to earth

- Suitable for a high leakage current.

■ Extreme running conditions

Motor-generated overvoltage 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.

Mains drop-out 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.

Static overload 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.

Special conditions

■ Acoustic noise

Below are the typical values measured at a distance of 1 m from the unit at full load:

2 pole 4 pole FCM 305 54 dB(A) FCM 311 58 dB(A) FCM 315 59 dB(A) FCM 322 58 dB(A) FCM 330 61 dB(A) FCM 340 62 dB(A) 63 dB(A) FCM 355 64 dB(A) 60 dB(A) FCM 375 61 dB(A)

Balance

The FCM 300 is balanced to class R according to ISO2373 (reduced balance). For critical applications especially at high speed (>4000 RPM) special balance (class S) might be required.

FCM 300 Series

MG.03.B6.02 - VL T is a register ed Danfoss trademark86

Special conditions

■ Derating

The FCM 300 Series motor is thermally protected in case limits are exceeded. At high temperatures the switching frequency will be gradually reduced down to 2 kHz and eventually the motor will trip.

■ Derating for ambient temperature

The ambient temperature (T

AMB,MAX

) is the maximum

temperature allowed. The average (T

AMB,AVG

) measured

over 24 hours must be at least 5ºC lower.

If FCM 300 Series is operated at temperatures above 40 ºC, a derating of the continuous output current is necessary.

■ Derating for air pressure

Below 1000 m altitude no derating is necessary.

Above 1000 m the ambient temperature (T

AMB

) or

max. output current (I

VLT,MAX

) must be derated in

accordance with the following diagram:

1) Derating of output current versus altitude at T

AMB

= max. 40°C

2) Derating of max. T

AMB

versus altitude at 100%

output current.

■ 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 6).

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

FCM 300 Series

MG.03.B6.02 - VL T is a register ed Danfoss trademark

■ 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 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.

■ Vibration and shock

FCM 300 Series has been tested according to a procedure based on the following standards:

IEC 68-2-6: Vibration (sinusoidal) - 1970 IEC 68-2-34: Random vibration broad-band

- general requirements

IEC 68-2-35: Random vibration broad-band

- high reproducibility

IEC 68-2-36: Random vibration broad-band

- medium reproducibility

FCM 300 Series complies with requirements that correspond to conditions in the standards mentioned above.

■ Air humidity

FCM 300 Series has been designed to meet the IEC 68-2-3 standard, EN 50178 item 9.4.2.2/DIN 40040, class E, at 40°C.

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:

THD = (%)

■ 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

with 50 Hz as the basic frequency:

Harmonic currents I

7 I11

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.

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

■ What is CE labelling?

The purpose of CE labelling is 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:

■ The machinery directive (89/392/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.

■■

■ 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.

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 is a 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 the EMC directive is issued.

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.

■ 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 ef fects to some extent.

The VLT frequency converter should not therefore be installed in environ-

ments with airborne liquids, particles or gases capable of affecting and damaging the electronic components. Failur e 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,

corrosive gases such as sulphur, nitrogen and chlorine compounds will cause chemical processes on the VLT frequency converter components. Such chemical reactions will rapidly affect and damage the electronic components.

NOTE!

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.

Wherever a cross is placed under both Warning and 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.

Warnings and alarms

What if the motor does not start?

- 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 no STOP command have been issued by the optional control panel keyboard (local stop) Control Panel STOP can only be restarted by the Control Panel START button.

Warnings

The display flashes between normal state and warning. A warning comes up on the first and second line of the display. See examples below:

WARNING/ALARM 2 Live zero fault (LIVE ZERO ERROR):

The current signal on terminal 1 is less than 50% of the value set in parameter 336 Terminal 1, min. scaling.

WARNING/ALARM 4 Phase loss (MAINS PHASE LOSS):

Phase missing on the supply side. Check the supply voltage to the FC motor.

WARNING 5 Voltage warning high (DC LINK VOLTAGE HIGH):

The intermediate circuit voltage (DC) is higher than the overvoltage limit of the control system, see table on this page. The FC motor is still active.

WARNING 6 Voltage warning low (DC LINK VOLTAGE LOW):

The intermediate circuit voltage (DC) is below the undervoltage limit of the control system, see table below. The FC motor is still active.

ALARM 7 Overvoltage (DC LINK OVERVOLT):

If the intermediate circuit voltage (DC) exceeds the inverter overvoltage limit (see table), the FC motor will trip. Furthermore, the voltage will be stated in the display.

ALARM 8 Undervoltage (DC LINK UNDERVOLT):

If the intermediate circuit voltage (DC) drops below the inverter lower voltage limit (see table on this page), the FC motor will trip after 3 - 28 sec., depending on unit. Furthermore, the voltage will be stated in the display. Check whether the supply voltage matches the FC motor, see technical data.

WARNING/ALARM 9 Inverter overload (INVERTER TIME):

The electronic, thermal inverter protection reports that the FC motor is about to cut out because of an overload (too high current for too long). The counter for electronic, thermal inverter protection gives a warning at 95% and trips at 100%, while giving an alarm. The FC motor

cannot be reset until the counter

is below 90%.

The voltages stated are the intermediate circuit voltage of the FC motor.
