Brief Product Description
The VLT 5000 Crane frequency converter supplies a motor with variable voltage and frequency and thereby enables infinitely variable speed control of three-phased standard AC-motors.
The VLT 5000 Crane features the Flux Vector control system.
The VLT 5000 Crane uses a digital technique making it possible to program the different control inputs and signal outputs.
The user can easily program the desired functions by means of the VLT 5000 Crane control panel or the user interfaces RS485 and RS232.
The VLT 5000 Crane is protected against the transients occurring in the mains supply. Furthermore, a good power factor and low peak current, reducing the load on the mains installation, are ensured through intermediate circuit coils.
Current measurement on all three motor phases perfectly protects VLT 5000 Crane against earthing and short-circuiting faults on the motor connenction.
VLT® 5000 Crane
Introduction
VLT 5000 Crane offers:
Full utilisation of control range
130% torque for acceleration
Fine adjustment at standstill + full load possible
without activating the system brake
System Description
The sketch on next page shows how a tower crane works together with VLT Crane Control.
The system consists of the following:
Efficient monitoring of the mains supply phases ensures that the unit stops in case of phase failure. This eliminates the risk of overloading the inverter an the capacitors in the intermediate circuit and thereby prolongs the service life of the frequency converter.
As standard, VLT 5000 Crane features integral thermal protection. If a situation of thermal overload occurs, this function cuts out the inverter.
The VLT 5000 Crane features reliable galvanic isolation on all control terminals and integrated electronic thermal protection on the motor.
Function and System Description
With VLT 5000 Crane the speed is infinitely varied in the whole speed range from standstill (0 RPM) until rated speed (750 RPM for VLT 5052-5072, 1125 RPM for VLT 5102) according to the CT characteristic and rated power up to max. speed (3000 or 4500 RPM).

Normal operation
The reference signal is higher than minimum. Up to 750 RPM the working range is limited by max. torque. Above 750 RPM it is working in field weakening range. Here the working range is limited by constant power.
MG.50.N4.02 - VLT is a registered Danfoss trademark
VLT 5000 Crane controls the mechanical brake of the crane. It holds the load when speed is below the set minimum value.
VLT 5000 Crane monitors that the system brake holds and releases the load as required. In case of faults, Brake fault 2 is displayed.
Load determination and speed measuring will ensure that the working range is not exceeded. For each load contact the max. allowed motor speed is set (parameters 701 and 702). VLT 5000 Crane cuts off automatically when motor speed for the activated load contact exceeds the value recorded
Positioning
The reference signal is higher than minimum. The condition for VLT ready is fulfilled. 24V is applied to terminal 17 (parameter 301).
During positioning the speed is limited to 750 RPM for VLT 5052-5072, 1125 RPM for VLT 5102, 1500 RPM for VLT 5152-5202, respectively, and system brake is not activated at 0 RPM.
Quick stop with brake
If control signal to terminal 27(parameter 304) is removed, the motor ramps down according to the alternative ramp (parameter 212) and the brake is activated momentarily.
Operating Status at Local Operation
It is only possible to change to local operation from Control Ready. Besides, parameter 003 must be set for Local and parameter 010 for Enable.VLT 5000 Crane can be operated over the control panel or over parameters 004 - 009. This state acts as Normal operating state, however there are no load functions and monitoring of system brake. This means that the whole working range from 0
- 3000 RPM can be used and the crane system brake is controlled at approx. 0 RPM.
VLT® 5000 Crane
Brake fault 2
VLT 5000 Crane monitors in the state normal operation, that the system brake releases the load as required. If that is not the case Brake fault 2 applies. The unit will cut in the system brake again. This means that the system brake signal is deactivated. This ensures that the load is held. Then the inverter section is disabled.
Brake fault 2 may also occur during commissioning if the encoder connection is not correct. Atreference0theunitgoesbacktothestateVLTready.
Function fault
VLT 5000 Crane monitors several functions. Should severe faults occur, the unit will trip automatically. For fault types, see Trouble-shooting To reset the fault switch off/switch on the mains supply and press the stop/reset button.

Control Principle
A frequency converter rectifies AC voltage from mains into DC voltage. This DC voltage is then converted into aACvoltagewithavariableamplitudeandfrequency.
1. Mains voltage 3 x 400 - 500 V AC, 50 / 60 Hz.
2
. Rectifier A three-phase rectifier bridge that rectifies AC voltage into DC voltage.
3
. Intermediate circuit
The motor is thus supplied with variable voltage and frequency, which enables infinitely variable speed control of three-phased, standard AC motors.
5
. Intermediate circuit capacitors
Smooth the intermediate circuit voltage.
. Inverter
6 Converts DC voltage into variable AC voltage with a variable frequency.
. Motor voltage
7 Variable AC voltage, 0-100% of mains supply voltage. Variable frequency: 0 - 300 Hz.
4. Intermediate circuit coils Smooth the intermediate circuitcurrent and limit the load on mains and components (mains transformer, wires, fuses and contactors).
Flux Vector Control Principle
TheaimofdevelopingtheFluxVectorcontrol principle has been to obtain a robust motor control that is tolerant to different motor characteristics without motor derating being required.
The current is split into magnetising and torque-generating parts and provides for much better and quicker estimation of the actual motor loads. It is now possible to compensate for rapid load changes. Full torque as well as extremely accurate speed control can now be obtained even at low speeds or even at standstill.
Good torque control properties and smooth transitions to and from current limit operation are ensured.
Advantages of the Flux Vector control system:
- Accurate speed control down to 0 speed
- Quick response from received signal to
full motor shaft torque
- Good compensation for step loads
- Controlled transition from normal operation to
current limit operation (and vice versa)
. Control circuit
8 On basis of parameters, reference settings and input signals, pulse patterns are generated for forming thevariablemotorvoltageandfrequency.
- Torque control, comprising control of both the torque-generating and the magnetising component of the current
- Full holding torque
P
rogrammable signal outputs VLT 5000 Crane uses a digital technique which makes it possible to program the signal outputs.
For the user, it is easy to program the desired functions by means of the control panel on VLT 5000 Crane or the RS 485/RS 232 user interfaces.
rotection against mains interference
P VLT 5000 Crane is protected against the transients that occur in the mains supply, eg. when switching power factor correction or when fuses blow.
The rated motor voltage and full torque can be maintained all the way down to 10% undervoltage in the mains supply.

VLT® 5000 Crane
Minor interference on mains Since as standard the VLT 5000 Crane features intermediate circuit coils, there is only a small amount of harmonic mains supply interference. This ensures a good power factor and lower peak current, which reduces the load on the mains installation.
A
dvanced VLT protection Current measurement on all three motor phases provides perfect protection of VLT 5000 Crane against earthing and short-circuiting faults on the motor connection.
Efficient monitoring of the three mains supply phases ensures that the unit stops in the case of phase failure. This avoids overloading the inverter and the capacitors in the intermediate circuit, which would dramatically reduce the service life of the frequency converter.
As standard, VLT 5000 Crane features integral thermal protection. If a situation of thermal overload occurs, this function cuts out the inverter.
ncoder supervisory circuit
E The signals from the incremental encoder and hence the cabling are continuously supervised. The encoder signals are made up of three channels, each of which are supervised, and status is given on LEDs placed near the encoder terminals for each channel as well as for the supply voltage for the encoder. Green LED turned on means channel or voltage OK.
fan fails, a thermistor can be integrated and connected to the thermistor input of the frequency converter (terminals 53), see parameters 128 and 308.
Introduction
R
eliable galvanic isolation In the VLT 5000 Crane all of the control circuits are separated from mains potential through isolation meeting the PELV requirements. One set of relay contacts, terminals 01 - 03, is separated from the remaining control circuits through isolation also complying with PELV. Furthermore, the control circuits are placed in blocks individually separated through functional isolation (< 100 V), see General Technical Data.
A
dvanced motor protection VLT 5000 Crane features integrated thermal motor protection.
The frequency converter calculates the motor temperature on the basis of current, frequency and time.
As opposed to the traditional bimetallic protection, electronic protection takes ac cooling at low frequencies that comes from reduced fan speed (motors with internal ventilation).
To obtain maximum protection against overheating of the motor if the motor is covered or blocked, or if the

VLT 5000 Crane Protection
Electronic motor thermal protection against overload
Electronic thermal protection against overload
Temperature monitoring of heat-sink ensures that the frequency converter cuts out if the temperature reaches
90°C. An overtemperature fault can only be reset when the temperature of the heat-sink has fallen below 60°C
The frequency converter is protected against short-circuiting on motor terminals U, V, W
The frequency converter is protected against earth fault on motor terminals U, V, W
Monitoring of the intermediate circuit voltage ensures that the frequency converter cuts out if
the intermediate circuit voltage gets too high or too low
If a motor phase is missing, the frequency converter cuts out, see parameter 234 Motor Phase Monitor
If a mains phase is missing, the frequency converter will cut out when a load is applied to the motor

Electrical Installation
The voltage on the frequency converter is dangerous when the unit is connected to
mains. Incorrect installation of the motor or frequency converter 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 15 minutes if using VLT 5052-5102.
NB!:
It is the users or certified electrician’s
responsibility to ensure correct earthing and protection in accordance with applicable
national and local norms and standards.
All terminals for the control cables are located under the protective cover of the frequency converter. The protective cover (see drawing) can be removed by means of a pointed object - a screwdriver or similar.

Installation of Motor Cables
NB!:
If an unscreened cable is used, some EMC requirements are not complied with, see
Special conditions in Appendix.IftheEMC specifications regarding emission are to be complied with, the motor cable must be screened, unless otherwise stated for the RFI filter in question. It is important to keep the motor cable as short as possible to reduce the noise level and leakage currents to a minimum. The motor cable screen must be connected to the metal cabinet of the frequency converter and to the metal housing of the motor. The screen connections are to be made with the biggest possible surface (cable clamp). This is enabled by different installation devices in the different frequency converters.
Mounting with twisted screen ends (pigtails) is to be avoided, since these spoil the screening effect at higher frequencies. If it is necessary to break the screen to install a motor isolator or motor contactor, the screen must be continued at the lowest possible HF impedance.

The frequency converter has been tested with a given length of cable and a given cross-section of that cable. If the cross-section is increased, the cable capacitance
- and thus the leakage current - increases, and the cable length must be reduced correspondingly.

EMC-Correct Electrical Installation
General points to be observed to ensure EMC-correct electrical installation.
- It is important to ensure good electrical contact from the installation plate through the installation screws to the metal cabinet of the frequency converter.
- Use toothed discs and galvanic conductive
- Use only screened/armoured motor cables and screened/armoured control cables.
- Connect the screen to earth at both ends.

- Do not use unscreened/unarmoured motor cables in the installation cabinets.
- Avoid installation with twisted screen ends (pigtails), since this ruins the screening effect at high frequencies. Use cable clamps instead.

Earthing of Braided Screened/armoured
Control Cables
Generally speaking, control cables must be braided screened/armoured and the screen must be connected by means of a cable clamp at both ends to the metal cabinet of the unit. The drawing below indicates how correct earthing is carried out and what to be done if in doubt.
1. Correct earthing
Control cables and cables for serial communication must be fitted with cable clamps at both ends to ensure the best possible electrical contact.
2. Wrong earthing
Do not use twisted cable ends (pig­tails), since these increase the screen impedance at high frequencies.
3. Protection with respect to earth potential
between PLC and frequency converter
If the earth potential between the frequency converter and the PLC (etc.) is different, electric noise may occur that will disturb the whole system. This problem can be solved by fitting an equalising cable, to be placed next to the control cable. Minimum cable cross-section: 16 mm
4. For 50/60 Hz earth loops
If very long control cables are used, 50/60 Hz earth loops may occur. This problem can be solved by connecting one end of the screen to earth via a 100nF capacitor (keeping leads short).
5. Cables for serial communication
It is recommended to use twisted-pair cables to reduce the differential mode interference between the conductors.

Safety Earthing
NB!:
The frequency converter has a leakage current and must be earthed appropriately for safety reasons. Use earth terminal,
which enables reinforced earthing.
Apply national safety regulations.

The VLT 5000 Crane can be combined with an LCP control unit (Local Control Panel) which makes up a complete interface for operation and programming of the frequency converter. The LCP control panel can be installed up to 3 metres away from the frequency converter, eg. on a front panel, by means of the additional mounting kit.
The control panel is divided into five functional groups:
1. Display.
2. Keys used to change the display function.
3. Keys used to change the programme parameters.
4. Indicator lamps.
5. Local control keys.
Alldataisdisplayedviaa4-linealphanumeric display, which during normal operation will be able to continuously display 4 items of operating data and 3 operating modes. During programming all information needed for quick, effective parameter setup of the frequency converter will be displayed. As a supplement to the display there are three indicator lamps for voltage indication (ON), warning (WARNING) and alarm (ALARM) respectively. All frequency converter parameter Setups can be changed immediately from the control panel, after entering

General Advice on Programming
On the following pages the control keys for parameter set-up and the local control keys will be explained.
First, however, please draw attention to the difference between the [+]/[-] keys and the [<]/[>] keys. The [+]/[-] keys are used for:
Changing parameter numbers within a
parameter group
Changing parameter values
The [<]/[>] keys are used for:
Shifting between parameter groups
Moving the cursor when changing numeric values
For further details on the parameter groups, please refer to the table in Parameter Programming.
Example:
The configuration mode in parameter 100 is to be set to SPEED CLOSED LOOP.
1. Press Menu to get access to the parameters
2. Press the [>] key to enter parameter group 100
3. Press [Change Data]
4. Press the [+] key twice to select the data value [1] for SPEED CLOSED LOOP
5. Press [OK]
6. The parameter is now set
Control keys for parameter Setup
The control keys are divided into functions, in such a way that the keys between the display and the indicator lamps are used for parameter Setup, including selection
of the displays view mode during normal operation.
[DISPLAY/STATUS] is used to select the displays
view mode or to change back to Display mode from either Quick Menu or Menu mode.
[QUICK MENU] provides access to the parameters
used in the Quick Menu. It is possible to switch between Quick Menu and Menu mode.
[MENU] gives access to all parameters. It is possible
to switch between Menu mode and Quick Menu.
[CHANGE DATA] is used to change a parameter that
has been selected either in Menu mode or Quick Menu.
Password Protection
To protect against unintended change of sensitive parameters, eg. motor parameters, some of the parameters are protected by a password. There are three levels of protection, for which two of the levels are protected by a password. The password protection is only accessable from the LCP, not from the serial bus communication. This means that all parameters are accessable from the bus eventhough they may be protected from the LCP. The three levels are the following:
Level 0: Danfoss service (not accessable)
Level 1: Commissioning (110775)
Level 2: Normal operation (000002)
NB!:
NOTE that level 1 and level 2 passwords must be re-entered after each power-up!
For further information on password protection see Parameter 650.
[CANCEL] is used if a change to the selected
parameter is not to be implemented.
[OK] is used to confirm a change to a
selected parameter.
[+ / -] are used for selecting parameters and
for changing parameter values. These keys are also used in Display mode to switch between the readouts of operating variables.
[< >] are used for selecting parameter group and to
move the cursor when changing a numerical value.

Local control
[STOP/RESET] is used for stopping the motor
connected or for resetting the frequency converter after a drop-out (trip). Can be set to active or inactive via parameter 014 Local stop. If stop is activated Display line 2 will flash.
NB!:
If an external stop function is not selected and the [STOP/RESET] key is set to inactive, the motor can only be stopped by disconnecting
the voltage to the motor or the frequency converter.
VLT® 5000 Crane
[FWD / REV] changes the direction of rotation of
the motor, which is indicated by means of the arrow on the display. Can be set to active or inactive via parameter 016 Local reversing. The [FWD/REV] key is only active when parameter 002 Local/remote operation is set to Local control.
NB!:
Note that the fwd/rev function is not active in crane profile. The function only functions if the VLT is programmed to run as a normal
VLT 5000 (see parameter 512).
[START] is used to start the frequency converter. Is
always active, but cannot override a stop command.
NB!:
If the local control keys are set to inactive, these will both become active when the
frequency converter is set to Local control and Remote control via parameter 002 Local/remote operation, with the exception of [FWD/REV], which is only active in Local control.
[JOG] overrides the output frequency to a preset
frequency while the key is pressed down.
NB!:
The Jog function is not available in crane profile.
If the VLT 5000 Crane is programmed to run
as a normal VLT 5000 (see parameter 512), the Jog function will, however, be available.

The functions are described further below:
Crane ready input signal for system ready. Positioning is selected if the frequency converter
is to work in positioning mode. Positioning mode is only available when running in remote control. If the signal is removed, the frequency converter is to operate in normal mode.
Start lowering is selected when the frequency
converter is to lower a load. This function is only available in remote control.
Start hoisting this function enables hoisting of a load
when the frequency converter is in remote control.
Quick stop ramps the motor speed down to zero
with the selected quick ramp time.
Gear choice is used whenever the gear is changed
in order to perform a load estimation. The function is only available in remote control.
Load contact 1 is the high load contact, which is used
for load monitoring when operating in remote control.
Load contact 2 is the low load contact,
which is also used for load monitoring when operating in remote control.

Start (START) [1] Reversing (REVERSING) [1] Jog (JOGGING) [4] [4] [5][4] [4]
Function:
The different possible functions related to the inputs on terminals 16-33 listed in the table above, are only accessable when running in FC profile.. The maximum frequency for terminal 16, 17, 18, 19, 27, 32, 33 and 37 is 5 kHz. The maximum frequency for terminal 29 is 50 kHz.
Description of choice:
No function is selected if the frequency converter is
not to react to signals transmitted to the terminal.
Reset zeroes the frequency converter after an alarm;
however, not all alarms can be reset.
Coasting stop inverse is used for making the
frequency converter let go of the motor to make it coast
freely to stop. 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. 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 (start-disable) are to be used as disconnection switch in connection
with repairs. Cut mains instead.
Start, is selected if a start/stop (operating
command, group 2) command is desired. Logic
1= start, logic 0=stop. Reversing is used for changing the direction of rotation
of the motor shaft. Logic ’1’ will lead to reversing.
The reversing signal only changes the direction of rotation; it does not activate the start function.
Jog is used for overriding the output frequency to
the jog frequency set in parameter 213. The ramp time can be set in parameter 211. Jog is not active if a stop command has been given (start-disable). Jog does not override a start signal.
NB!:
The Jog function is not available in Crane profile. If the VLT 5000 Crane is programmed to run as a normal VLT 5000 (see parameter 512),
the Jog function will, however, be available.

Resistor brake (RESISTOR)
Function:
The factory setting is On [1] for VLT 5052-5062 400-500 V. Resistor brake [1] is used for programming the frequency converter for connection of a brake resistor. The connection of a brake resistor allows a higher intermediate circuit voltage during braking (generating operation).

403 POWER MONITORING
Value:

Warning (WARNING)
Trip (TR I P)
Function:
This parameter allows monitoring of the power transmitted to the brake resistor. The power is calculated on the basis of the resistor ohm value (parameter 401), the intermediate circuit voltage and the resistor running time. If the power transmitted over 120 sec. exceeds 100% of the monitoring limit (parameter 402) and Warning [1] has been selected, a warning will come up on the display. The warning will disappear if the power goes below 80%. If the calculated power exceeds 100% of the monitoring limit and Trip [2] has been selected in parameter 403 Power monitoring , the VLT frequency converter will cut out while giving an alarm. If power monitoring has been selected as Off [0] or Warning [1], the brake function will remain active, even if the monitoring limit has been exceeded. This may lead to thermal overload of the resistor. It is also possible to have a warning via the relay/digital outputs. The typical measuring accuracy of the power monitoring depends on the accuracy of the resistor ohmic value (better than ± 20%).

Bus connection RS 485
The serial bus connection is connected to terminals 68/69 of the frequency converter (signals P and N) in accordance with the RS 485 (2-wire) norm. Signal P is the positive potential (TX+,RX+), while signal N is the negative potential (TX-,RX-).
If more than one frequency converter is to be connected to a given master, use parallel connections.
VLT® 5000 Crane
Hardware connection of the RS 232:
Pin 1 is connected to pin 6 on the control card, which results in the PC receiving a "Clear to Send" when it sends a "Request to Send".
In order to avoid potential equalizing currents the circuit driving terminals 68 and 69 are connected to the VLT chassis ground via a 100
us termination
B The bus must be terminated by a resistor network at both ends. For this purpose, set switches 2 and 3 on the control card for "ON", see Switches 1-4.
Bus Connection RS 232
The purpose of the RS 232 is to enable communication between a PC and one VLT. With this communication it is possible to monitor, programme and control the VLT.
However, it is not possible to use the RS 232 concurrently with the RS 485. When using one of the buses, the other must be disconnected, ie. when using eg. the RS 232, the RS 485 plug must be removed from the board.
resistor.
When looking into the RJ-11, pin 1 is the left terminal.
Danfoss offers a cable with an RJ-11 male plug in both ends and an adaptor between RJ-11 and Sub-D 9 Pole (for PC connection).

This is possible, eg. in parameter 404 Brake Check. After a trip, alarm and warning will flash, but if the fault is removed, only alarm will flash. After a reset, the frequency converter will be ready to start operation again.

Derating for Running at Low Speed
When a motor is connected to a frequency converter, it is necessary to check whether the cooling of the motor is adequate. At low RPM values, the motor fan is not able to supply the required volume of air for cooling. This problem occurs when the load torque is constant (e.g. a conveyor belt) across the regulating range. The reduced ventilation available decides the size of thetorquethatcanbepermittedunderacontinuous load. If the motor is to run continuously at an RPM value lower than half the rated value, the motor must be supplied with additional air for cooling. Instead of such extra cooling, the load level of the motor can be reduced. This can be done by choosing a bigger motor. However, the design of the frequency converter sets limits as to the size of motor that can be connected to it.

Serial Communication
Telegram Communication
ontrol and reply telegrams
C Telegram communication in a master-slave system is controlled by the master. A maximum of 31 slaves ( 5000 Crane) can be connected to one master, unless a repeater is used. If a repeater is used, a maximum of 126 slaves can be connected to one master.
The master sends control telegrams addressed to the slaves and awaits reply telegrams from these. The response time of the slaves is maximum of 50 ms.
A slave responds by sending a reply telegram when it has received telegram with corr STX, LGE, ADR and BCC..

roadcast A master can send the same telegram at the same time to all slaves connected to the bus. In such broadcast communication, the slave does not send a reply telegram to the master, provided the telegram has been correctly received. Boradcast communication is set up in the address format (ADR).
C
ontent of a byte Each transferred character begins with a start bit. Subsequently, 8 data bits are transferred. Each character is secured via a parity bit, which is set to "1"whenthereisevenparity(i.e. anevennumber
of binary 1sinthe8databitsandtheparitybit
combined). A character ends with a stop bit, thus consisting of a total of 11 bitsl.
Appendix
Telegram Build-up
Each telegram begins with a start byte (STX) = 02 Hex, followed by a byte that states the telegram length (LGE) and a byte that states the address of the frequency converter (ADR). Then follows a number of data bytes (variable, depending on telegram type). The telegram ends with a data control byte (BCC).

Telegram timing The speed of communication between a master and a slave depends on the baud rate. The baud rate of the frequency converter must be the same as the baud rate of the master and is selected in parameter 501 Baud rate. After a reply telegram from the slave, there must be a minimum pause of 2 characters (22 bits) before the master is able to send another telegram. At a baud rate of 9600 baud, there must be a minimum pause of 2.3 msec. After the master

VLT® 5000 Crane
has completed the telegram, the response time of the slave back to the master will be max. 20 msec. and there will be a minimum pause of 2 characters.
Pause time, min. 2 characters Response time, min. 2 characters Response time, max. 20 msec.
The time between individual characters in a telegram is not to exceed 2 characters and the telegram must be completed within 1.5 times the rated telegram time.
If the baud rate is 9600 baud and the telegram length is 16 characters, the telegram must be completed within 27.5 msec.
T
elegram length (LGE) The telegram length is the number of data bytes plus the address byte ADR plus the data control byte BCC.
Telegrams with 4 data bytes have a length of: LGE=4+1+1=6bytes Telegrams with 12 data bytes have a length of: LGE=12+1+1=14bytes
E
xample A telegram is sent to frequency converter address 22 using address format 1-31:
7 6 5 4 3 2 1 0 0 0 0 1 0 1 1 0
Data control byte (BCC) The data control byte is the EXOR-sum of the entire telegram. It is best explained by means of an example: Before the first byte of the telegram is received, BCC is 0.
When the first byte has been received: BCC
NEW
=BCC
EXOR "first byte"

(EXOR = exclusive-or gate)

V
LT address (ADR) Two different address formats are used, in which the address range of the frequency converter is either from 1-31 or from 1-126.:
1 Address format 1-31 The byte for this address range has the following profile:
Bit 7 = 0 (address format 1-31 active) Bit 6 is not used Bit 5 = 1: Broadcast, address bits (0-4) are not used Bit 5 = 0: No Broadcast Bit 0-4 = Frequency converter address 1-31
2. Address format 1-126: Thebyteforthe1-126addressrangehas the following profile:
Each subsequent byte gates with BCC and produces a new BCC
BCC
OLD
=00000010
NEW
, e.g.:
OLD
EXOR 2ndbyte =11010110(D6H) BCC
NEW
=11010100
The result after the latest incoming byte is BCC.
Databytes
The build-up of data blocks depends on the type of telegram. There are three types of telegram and the telegram type applies to both control telegram
(masterslave) and reply telegram (slavemaster).
The three types of telegrams are the following:
1. Parameter block, used for transferring parameters between master and slave. The data block has 12 bytes 6 words and also contains the process block.
EXOR
Bit 7 = 1 (address format 1-126 active) Bit 0-6 = Frequency converter address 1-126 Bit 0-6 = 0 Broadcast
The slave sends the address byte back to the master in the reply telegram in unchanged form.
96
2. Process block, built up as a data block with four bytes (2 words), covering:
- Control word and reference value (from master to slave)
- Status word and present output frequency (from slave to master)

Index is used together with the parameter number for read/write-access to parameters with an index, such as parameter 615 Error code. Index has 2 bytes - a lowbyte and a highbyte. However, only the lowbyte is used. See example below:

9 Visible string 10 Byte string 13 Time difference 33 Reserved 35 Bit sequence
The frequency converter will respond in the parameter value (PWE) block by means of an error code with a value from 1-99.
Parameter value (PWE)
The parameter value block consists of 2 words (4 bytes) and its value depends on the command given (AK). If the master enquires about parameter value, the PWE block contains no value.
If a parameter value is to be changed by the master (write), the new value is entered in the PWE block and sent to the slave.
The transferred text corresponds to the figures given in the parameter descriptions in the manual. Eg. parameter 001 Language, where [0] corresponds to English, and [2] corresponds to French. However, parameters with data type 9 (text string) are excepted, as this 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. Parameters 621-631 (nameplate data) have data type 9 (text string).
Unsigned means that there is no sign included in the telegram.
Conversion: The different attributes for each parameter can be seen in the section on factory settings. Since a parameter value can only be transferred as a whole number, a conversion factor must be used to transfer decimals.
E
xample: Parameter 202 Output speed high limit has a conversion factor of 0.1. If you wish to preset the minimum frequency to 10 Hz, the value 100 must be transferred, as a conversion factor of 0.1 means that the value transferred is multiplied by 0.1. The value 100 will thus be perceived as 10.0. See also Conversion and Unit of measurement.
Process bytes
The process byte block is divided into two blocks each of 16 bits, which always come in the sequence stated.
