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 condi- tions".

*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, cient .

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.

these stop functions are not suffi-

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.

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 be screwed

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 kept in place during storage. Shafts should be rotated

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

Installation of the FC motor

VLT® FCM Series

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.

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.

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.

NB!

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

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

Maintenance

Routine cleaning of the FC motor Remove the fan cover and ensure that all air inlet holes are completely free. Clean any dirt and obstructions from behind the fan and along the ribs of the frame, and between the motor and inverter part.

Periodic maintenance of motor part.

a. Remove the inverter part, the fan cover and

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. That problem is solved by mounting a FV unit.

Typical applications are for example conveyors, spindles and other constant torque (CT) applications 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 66. Approved according to UL.

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

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. Ensure that the electrical connections are correct.

f. Refit any pulley, coupling, sprocket etc.

Voltage range for forced ventilation (FV) unit

The FVU can be supplied with a wide range of voltages depending on the way the terminals are connected. Standard is three phase 380-500 V (50 Hz), 380-575

FCM 300 Thermal Protection

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

1. Overload situations are handled by the cal-

culated electrical load (I

X t).

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).

V (60 Hz) with the possibility to connect three phase 220-290 V (50 Hz), 220-332 V (60 Hz) or single phase 230-277 V (50/60 Hz). The capacitor for single phase is mounted inside the terminal box.

Trip level => Immediate trip and alarm indication (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.

The value can be read in parameter 527. (LCP:FC thermal)..

Temperature measurement The temperature measurement is sensing the temperature within the electronics box.'

At warning level => Warning indication goes on (LED and status word) and the unit might trip if the temperature doesn't sink back below warning level within 15 minutes. If the function TEMP.DEP.SW is activated in parameter 412, the switching frequency is decreased gradually down to 2 kHz attempting to decrease the temperature.

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 LEDand a yellow warning LED, as well as a green voltage LED.

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.

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.

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.

Keys for local control are found under the indicator LEDs.

[<>] 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.

VLT® FCM Series

[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 after stop via the [Stop] key. Is always active, but cannot override a stop command given via the terminal strip.

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.

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:

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).

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

• 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.

128 Motor thermal protection

(MOTOR THERM. PROTEC.)

Value:

No protection (NO PROTECTION) [0]

Function:

Read only parameter Please refer to section FCM 300 Thermal protection.

132 DC braking voltage

(DC BRAKE VOLTAGE)

Value:

0 - 100 % [0-100] 0 % [0]

Function:

DC braking:

If the stator in an asynchronous is supplied with DC voltage, a braking torque will arise. The braking torque depends on the selected DC braking voltage. For applying a braking torque by means of DC braking the rotating field (AC) in the motor is exchanged with a stationary field (DC)˙ The DC braking will be active when below cut in frequency and stop is activated at the same time. P126, P127 and P132 are used for the control of the DC braking. The DC braking can also be activated directly by a digital input.

Function:

The braking torque depends on the selected DC braking voltage. The DC braking voltage is stated as a percentage of maximum braking voltage.

NB!

The DC braking voltage cannot be used as a holding brake.

133 Start voltage

(START VOLTAGE)

Value:

0.00 - 100.00 V [0-10000] Depends on motor

Function:

You can set the motor voltage below the field weakening point independently of the motor current. Use this parameter to compensate too low starting torque.

The start voltage is the voltage at 0 Hz.

NB!

If the start voltage is set too high, it can lead to magnetic saturation and motor overheating; the FC motor may trip. Therefore take care when using the start voltage.

Description of choice:

Set the desired start voltage.

134 Load compensation

(LOAD COMPENSATION)

Value:

0.0 - 300.0 % [0-3000]

100.0 % [1000]

Function:

In this parameter, the load characteristic is set. By increasing the load compensation, the motor is given an extra voltage and frequency supplement at increasing loads. This is used e.g. in motors/applications in which there is a big difference between the full-load current and idle-load current of the motor.

NB!

If the value is too high the FC motor can trip due to overcurrent.

Description of choice:

Set the desired voltage as a specified percentage of maximum braking voltage.

42 MG.03.H6.02 - VLT® is a registered Danfoss trademark

VLT® FCM Series

Description of choice:

If the factory setting is not adequate, load compensation must be set to enable the motor to start at the given load.

Should be set to 0% in case of quick load changes. Too high load compensation may lead to instability.

135 U/f ratio

(U/F RATIO)

Value:

0.00 - 20.00 V/Hz [0-2000] Motor dependent

Function:

The output voltage to the motor can be adjusted on a linear basis from 0 to rated frequency.

137 DC holding voltage

(DC HOLD VOLTAGE)

Value:

0 - 100 % [0-100] 0 (OFF) % [0]

Function:

This parameter is used to uphold the motor function (holding torque) or to pre-heat the motor. DC holding voltage is active at stopped motor when it is set at a value which is different from 0. Coasting stop will deactivate the function.

Description of choice:

Enter a percentage value.

138 Brake cut out frequency

(BRAKE RELEASE)

Value:

0.5 - 132 Hz (parameter 200) [5-]

3.0 Hz [30]

136 Slip compensation

(SLIP COMP.)

Value:

-500.0 - +500.0 % [-5000 - +5000]

100.0 % [1000]

Function:

The rated slip compensation (factory setting) is calculated on the basis of the motor parameters. In parameter 136 the slip compensation can be adjusted in detail. Optimizing makes the motor speed less load dependent. This function is not active at the same time as variable torque (parameter 101).

Function:

Here the frequency at which the external brake is to be released is selected via output set in parameter 323 or 340 during running.

Description of choice:

Set desired frequency.

139 Brake cut in frequency at activated stop

(BRAKE CUT IN)

Value:

0.5 - 132 Hz (parameter 200) [5-]

3.0 Hz [30]

Function:

NB!

This is only possible in Stop Mode (motor stopped on a Stop command). Ramp will be followed, if no set up change.

NB!

If parameter 200, selection of direction, is set for different values in the 2 setups, and the setup is changed during operation, the direction changes without ramping. In such cases trip may occur and that may reduce the service life of the power module, as well as it may be harmful to the application.

Therefore! It is recommended

not to set parameter 200 for different values in the 2 setups. If that should be necessary the user must make sure that setup changes are only made with stopped motor.

Function:

In this parameter, a maximum motor frequency can be selected that corresponds to the highest frequency at which the motor is to run.

Function:

In parameters 332-335 it is possible to choose between the different possible functions related to the inputs on terminals 2-5. The function options are shown in the table below.

Description of choice:

No function is selected if the FC motor is not to react to signals transmitted to the terminal.

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

MG.03.H6.02 - VLT® is a registered Danfoss trademark 53

Coasting stop, inverse is used for making the FC motor run freely to stop. Logic '0' leads to coasting stop.

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

Logic ‘0’ leads to coasting stop and reset.

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.

VLT® FCM Series

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, 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 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.

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).

Freeze output - freezes the actual motor frequency (Hz). The frozen motor frequency is now the point of enable/condition for Speed up and Speed down to be used.

Freeze output overrides start/stand-by, slip compensation and closed loop process control.

If speed up/down is used, the speed change always follows the normal ramp (parameters 207/208) in the range 0 - f

M,N

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).

Example: Terminal Freeze ref./

2-5 2-5 Freeze output No speed change 0 0 1 Speed down 0 1 1 Speed up 1 0 1 Speed down 1 1 1

Selection of Setup, enables a choice of one of the two Setups; however, this presupposes that parameter 004 has been set to Multi Setup.

Catch-up/Slow-down is selected if the reference value is to be increased or reduced by a programmable percentage value set in parameter 219.

Slow-down Catch-up Unchanged speed 0 0 Reduced by %-value 1 0 Increased by %-value 0 1 Reduced by %-value 1 1

Jog overrides stand-by.

Freeze reference - freezes the actual reference. The frozen reference is now the point of enable/ condition for Speed up and Speed down to be used.

If speed up/down is used, the speed change always follows the normal ramp (parameters 207/208) in the range 0 - Ref

MAX

Preset reference enables a choice of one of the two preset references, in accordance with the table in parameter 215 and 216. To be active, Preset reference, on has to be selected.

Preset reference is used for shifting between external reference and preset reference. It is assumed that Ex- ternal/preset [2] has been selected in parameter 214. Logic '0' = external references active; logic '1' = one of the two preset references is active.

Precise stop corrects the ramp-down time to obtain a high repetitive accuracy of the stopping point.

Pulse reference is selected if a pulse sequence (frequency) of 0 Hz is used, corresponding to Ref

, parameter 204. The frequency is set in parameter 327, corresponding to Ref

MAX

Pulse feedback is selected if a pulse sequence (frequency) is selected as a feedback signal. See also parameter 327.

Analogue reference is selected to enable change of reference by means of an analogue reference signal.

If other inputs are connected, these are added up, taking account of their signs.

Analogue feedback is selected if closed loop regulation with an analogue signal is used.

Reset and start is used for activating start at the same time as reset.

Freeze reference and start, both a START and a FREEZE REFERENCE command will be initiated. When using SPEED UP/SPEED DOWN both FREEZE REFERENCE and START must be activated. By implementing this feature a digital input can be spared.

Ramp 2, is selected if a shift between ramp 1 (parameters 207-208) and ramp 2 (parameters 209-210) is required. Logic "0" leads to ramp 1 and logic "1" leads to ramp 2.

Start-ref bit 1,2 and 3, makes it possible to select which REF RESET (1-7) is to be used. The REF PRESET (1-7) are set in parameters 241 to 247.

Parameter Group 4-** Special Functions

400 Brake functions

(BRAKE FUNCTIONS)

Value:

OFF (OFF) [0] AC brake (AC BRAKE) [4]

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.

VLT® FCM Series

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 reference or Jog has been selected The function is active in both Open loop and Closed loop.

In parameter 403 Sleep mode timer, the Sleep mode is activated. In parameter 403 Sleep mode timer, a timer 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.

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.

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.

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 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 set- point 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).

403 Sleep mode timer

(SLEEP MODE TIMER)

Value:

0 - 300 sec. (301 sec. = OFF)

OFF

Function:

This parameter enables the frequency converter to stop the motor if the load on the motor is minimal. The timer in parameter 403 Sleep mode timer starts when the output frequency drops below the frequency set in parameter 404 Sleep frequency. When the time set in the timer has expired, the frequency converter will turn off the motor. The frequency converter will restart the motor, when the theoretical output frequency exceeds the frequency in parameter 407 Wake up frequency.

Description of choice:

Select OFF if this function is not wanted. Set the threshold value that is to activate Sleep mode after the output frequency has fallen below parameter 404 Sleep frequency.

404 Sleep frequency

(SLEEP FREQUENCY)

Value:

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.

406 Boost setpoint

(BOOST SETPOINT)

Value:

1 - 200 %

100 % of setpoint

Function:

This function can only be used if Closed loop has been selected in parameter 100. In SYSTEMs with constant pressure regulation, it is advantageous to increase the pressure in the SYSTEM before the frequency converter stops the motor. This extends the time during which the frequency converter stops the motor and helps to avoid frequent starting and stopping of the motor, e.g. in the case of leaks in the water supply SYSTEM.

Use Boost Time-Out, par. 472, to set the boost timeout. If the boost set-point cannot be reached within the specified time, the frequency converter will continue in normal operation (Not entering sleep mode).

Description of choice:

Set the required Boost setpoint as a percentage of the resulting reference under normal operation. 100% corresponds to the reference without boost (supplement).

407 Wake up frequency

(WAKEUP FREQUENCY)

Value:

Par 404 Sleep frequency - par. 202 f

MAX

50 Hz

Function:

When the theoretical output frequency exceeds the preset value, the frequency converter restarts the motor.

Description of choice:

Set the required frequency.

411 Switching frequency

(SWITCH FREQ.)

Value:

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 temperature.

412 Variable switching frequency

(VAR CARRIER FREQ)

Value:

Not possible (DISABLE) [0] Variable switching freq. (VAR. CARRIER

FREQ.) [1] Temperature dep. sw. freq. (TEMP. DEP.

FREQ.) [2]

Function:

This function makes it possible to change the switching frequency depending on the load. However, the maximum switching frequency is determined by the value set in parameter 411.

Description of choice:

Select Not possible [0] if a permanent switching frequency is desired. Set the switching frequency in parameter 411.

If Variable switching frequency [1] is selected the switching frequency will decline at an increasing output frequency. This is used in applications with square torque characteristics (centrifugal pumps and fans) in which the load declines depending on the output frequency.

If Temperature dependent switching frequency [2] is selected, the switching frequency will decline at an increasing inverter temperature, see the drawing below.

413 Overmodulation function

(OVERMODULATION)

Value:

Off (OFF) [0] On (ON) [1]

Function:

This parameter allows connection of the overmodulation function for the output voltage.

Description of choice:

Off means that there is no overmodulation of the output voltage, which means that torque ripple on the motor shaft is avoided. This can be a good feature, e.g. on grinding machines.

On means that an output voltage can be obtained which is greater than the mains voltage (up to 5%).

Choose among different units to be shown on the display.

This unit is also used directly in Process regulation,

closed loop as a unit for Minimum/Maximum reference (parameters 204/205) and Minimum/ Maximum feedback (parameters 414/415).

The possibility of choosing a unit in parameter 416 will depend on the choices made in the following parameters:

Par. 002 Local/remote control. Par. 013 Local control/config. as par. 100. Par. 100 Configuration.

Select parameter 002 as Remote control If parameter 100 is selected as Speed regulation, open loop, the unit selected in parameter 416 can be used in displays (par. 009-12 Feedback [unit]) of process parameters. Note: The reference can only be shown in Hz (Speed regulation, open loop).

If parameter 100 is selected as Process regulation, closed loop, the unit selected in parameter 416 will be used when displaying both reference (par. 009- 12:

Reference [unit]) and feedback (par. 009-12: Feedback [unit]).

NB!

The above applies to display of Reference [unit] and Feedback [unit]. If Reference [%]

or Feedback [%] is selected, the value dis- played will be in the form of a percentage of the selected range.

Description of choice:

Select the desired unit for the reference/feedback signal.

FCM 300 Regulator

Process regulation 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.

Select parameter 002 as Local control If parameter 013 is chosen as LCP control and open loop or LCP digital control and open loop , the reference will be given in Hz, regardless of the choice made in parameter 416. If parameter 013 is chosen as LCP control/as par. 100 or LCP digital control/as par. 100, the unit will be as described above under parameter 002, Remote-control.

PID functions

Unit of reference/feedback

When Process regulation, closed loop is selected in parameter 100 Configuration the unit is defined in parameter 416 Reference/feedback unit:

Feedback 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 scaling.

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.

Reference In parameter 205 Maximum reference, Ref

it is pos-

MAX

sible 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.

Reference type

(241-247)

Bus reference 68+69

Note that the bus reference can only be preset via serial communication.

NB!

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

Differentiator gain limit 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.

Lowpass filter 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

Inverse regulation 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 .

Anti Windup 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.

Starting conditions 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 frequen- cy.

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.

437 Process PID Normal/inverse control

(PROC NO/INV CTRL)

Value:

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].

VLT® FCM Series

438 Process PID anti windup

(PROC ANTI WINDUP)

Value:

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!

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.

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.

440 Process PID proportional gain

(PROC. PROP. GAIN)

Value:

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.

439 Process PID start frequency

(PROC START VALUE)

Value:

MIN-fMAX

(parameter 201 and 202)

parameter 201

[X.X]

441 Process PID integral time

(PROC. INTEGR. T.)

Value:

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

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.

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).

= factory setting, () = display text, [] = value for use in communication via serial communication port

MG.03.H6.02 - VLT® is a registered Danfoss trademark 65

VLT® FCM Series

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 - 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.

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 [2 - 1000]

0.02 sec [2]

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.

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)

Value:

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).

The process regulator will thus back 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.

445 Flying start

(FLYING START)

Value:

Disable (DISABLE) [0] OK - same direction (OK-SAME DIRECTION) [1] OK - both directions (OK-BOTH DIREC-

TIONS) [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 ro-

tate 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.

Below 250 rpm the Flying start will not function.

446 Switching pattern

(SWITCH PATTERN)

Value:

60° AVM (60° AVM) [0] SFAVM (SFAVM) [1]

Function:

Description of choice:

Normally it is not necessary for the customer to set this parameter.

461 Feedback conversion

(FEEDBACK CONV.)

Value:

Linear (LINEAR) [0] Square root (SQUARE ROOT) [1]

Function:

In this parameter, a function is selected which converts a connected feedback signal from the process to a feedback value that equals the square root of the connected signal. 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.

Description of choice:

If Linear [0] is selected, the feedback signal and the feedback value will be proportional. If Square root [1] is selected, the frequency converter translates the feedback signal to be the square root value.

455 Frequency range monitor

(MON. FREQ. RANGE)

Value:

Function:

his parameter is used if warning 35 Out of frequency range must be turned off in the display in process con-

trol closed loop. This parameter does not affect the extended status word.

Serial bus

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.

VLT® FCM Series

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

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

1. Siemens USS protocol address format:

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.

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).

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

2. Danfoss format:

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.

After the first sign has been received: BCC

NEW

= BCC

EXOR "first byte"

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 fre-

quency (from slave to master)

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

There are two types of telegrams:

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.

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.

The transferred value corresponds to the figures given in the parameter descriptions in chapter 8. E.g. parameter 101, where [1] corresponds to Constant tor- que, [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).

Data types supported by the VLT frequency converter

Data type

3 Integer 16 4 Integer 32 5 Unsigned 8 6 Unsigned 16 7 Unsigned 32 9 Text string

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, a conversion factor must be used to transfer decimals.

Description

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.

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

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.

NB!

The use of Bit 00, Bit 01 and Bit 02 for switching off the power supply (by use of relay) will require a separate power on. This because there is no 24V external connection to supply the FCM 300 control, which is required to activate the FCM 300 again via input signal.

Bit 00, OFF1/ON1: An ordinary ramp stop which uses the ramp time in parameters 207/208. Bit 00 = "0" leads to a stop. 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. Bit 01 = "1" means that the frequency converter is able to start, provided the other conditions for starting have been fulfilled.

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

212. Bit 02 = "0" leads to a quick-stop. Bit 02 = "1" means that the frequency converter is able to start, provided the other conditions for starting have been 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.

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. 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. 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.

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.

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.

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.

Status word (according to Fieldbus Profile standard)

The status word is used for informing the master (e.g. a PC) of the condition of a slave (FC motor).

Bit 11, No function / slow down, relay 123, digital output terminal 9: 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 11 = “1” will also activate relay 123 (provided parameter 323 = “Control word bit 11”) and set digital out terminal 9 high (provided parameter 340 = “Control word bit 11”).

Bit 12, No function / catchup, relay 123: 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”).

Bits 13, Choice of Setup: Bit 13 is used for choosing between the two menu Setups in accordance with the following table:

Bit Bit = 0 Bit =1 00 Control not ready Ready 01 FC not ready Ready 02 Coasting Enable 03 No fault Trip 04 ON 2 OFF 2 05 ON 3 OFF 3 06 Start enable Start disable 07 No warning Warning 08 09 Local control Serial communication 10 Outside frequency

Data read-out: Terminal 2, analogue input

(ANALOG INPUT 2)

(PROTOCOL)

(M.BUS PAR./FRAME)

Function:

This parameter sets up the drive’s Modbus RTU interface to communicate properly with the master controller. The parity (EVEN, ODD, or NO PARITY) must be set to match the setting of the master controller.

Description of choice:

Select the parity that matches the setting for the Modbus master controller. Even or odd parity is sometimes used to allow a transmitted word to be checked for errors. Because Modbus RTU uses the more efficient CRC (Cyclic Redundancy Check) method of checking for errors, parity checking is seldom used in Modbus RTU networks.

NB!

Any change will disable use of display unit (LCP2), and further programming also by FC protocol.

571 Modbus communications timeout

(M.BUS COM.TIME.)

Value:

10 ms - 2000 ms

Function:

This parameter determines the maximum amount of time that the drive’s Modbus RTU will wait between characters that are sent by the master controller. When this amount of time expires, the drive’s Modbus RTU interface will assume that it has received the entire message.

Description of choice:

Generally, the value of 100 ms is sufficient for Modbus RTU networks, although some Modbus RTU networks may operate on a timeout value as short as 35 ms. If this value is set too short, the drive’s Modbus RTU interface may miss a part of the message. Since the CRC check will not be valid, the drive will ignore the message. The resulting retransmissions of messages will slow communications on the network. If this value is set too long, the drive will wait longer than necessary to determine that the message is completed. This will delay the drive’s response to the message and possibly cause the master controller to time out. The resulting retransmissions of messages will slow communications on the network.

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 , indicating the intermediate current volt-

age.

2. Gate drive that runs the IGBTs (optocou-

plers).

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, approx 4 to 20 mA. Varies with switching frequencies within the given interval.

This means reinforced earthing mus be established, 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.

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

This means it is possible to operate the FCM 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.

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 mo-

ment 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.

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 ISO8821 (reduced balance). For critical applications especially at high speed (>4000 RPM) special balance (class S) might be required.

Thermal Protection and 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.

NB!

Combination of high switching frequency and missing fan cooling might damage the unit.

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 (motor cooling method 2).

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

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.

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 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.

2 pole

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:

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:

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 distin-

guishes between components, appliances, SYSTEMs and installations.

What is covered?

The EU "Guidelines on the Application of Council Di-

rective 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

92 MG.03.H6.02 - VLT® is a registered Danfoss trademark

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.

General aspects of EMC emissions 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.

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.

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.

General aspects of EMC immunity 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.

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 MCT 10 Setup Software will not tell you what is wrong or what to do.
