2.3 Electrical Installation

2.3 Electrical Installation

If the RS232C/RS485 communication module is no longersupplied with voltage due to a fault, the bus system willcontinue operation.The connected inverter can however no longer be accessedfrom the host.

The polarity of the voltage supply must not be reversed,otherwise, the communication module will be destroyed!

Voltage supply:

• external 24 V (15 to 30 V) via plug–in connectors 39 (–)/59 (+)or

• internal via the inverter (connection by plugging it on).

Inverters with an extended AIF interface port (front of VF–C inverter) can have aninternal power supply. The greyed area in the diagram below shows the corres–ponding jumper position.

By default, external power supply is set. For internal power supply, you need toposistion the jumper as indicated below.

2.4 Wiring to a Host


This chapter informs about networking the communication module using the bussystems RS232C (LECOM–A) or RS485 (LECOM–B). The required accessories aredescribed in appendix A.1.

Warning!

� An additional electrical isolation is required if

– an inverter is connected to a host and

– a safe electrical isolation (double basicinsulation) according to VDE is required.

� Depending on the field bus used, observe thefollowing:

– RS232C: The electrical isolation of the RS232Cinterface (LECOM–A) can be achieved by twolevel converters (e.g. NAiS C–Net Adapter) oranother RS232C electrical isolation.

– RS485: With RS485 (LECOM–B), the NAiS C–Netlevel converter should be installed to thehost if it is not equipped with anappropriately isolated interface.

� For wiring, the electrical isolation of the supplyvoltage must be taken into account.

3.1 Before Switching On


Check the wiring for completeness, short circuit and earthfault before the inverter is connected to the mains.

Procedure: Observe the following switch–on sequence:

1. Switch on the inverter and – if required – the externalsupply of the communication module.The operating status display for the inverter (� figure 3 on page 2 – 3, Pos. �) must be on or blinking.

The green LED (� figure 3 on page 2 – 3, pos. �) must be on. If thisis not the case, � chapter 5.

2. The transmission speed or LECOM baud rate (C0125) isfactory set to 9600 baud. If a different value is required,adjust it via the operating unit.

3. Set the LECOM unit address (C0009) via the operatingunit or via the host (factory setting: 1).If several inverters are interconnected in a network, it must bepossible for the host to address each inverter uniquely. Every invertermust therefore have a different LECOM inverter address (C0009). Thevalues 00, 10, 20, 30, ..., 90 must not be set since they are reservedfor group addressing.

The code numbers C0009 (LECOM inverter address) and C0125(LECOM baud rate) can also be input via LECOM. Please observethat the parameters for the host must be adapted. If C0125 ischanged, the host will not recognize the response because theinverter has already transmitted it using the new baud rate.

Next steps:1. It is now possible to communicate with every inverter,

i. e. all code numbers can be read and all writeablecodes, except C046 (frequency setpoint) and C0135(control word) can also be changed.If codes C0046 and C0135 are to be changed as well, setC0003=3.

2. If the inverter is switched on while the operating modeC0001 = 3 is active and the speed setpoint is set to 0,QSP (quick stop) is active. Thus, the drive cannot start inan uncontrolled way. The QSP function can bedeactivated by setting bit 3 from C0135 to 0.

RS232C/RS485 Communication Module Parameter Setting


4.1 Overview

4.1 Overview

The parameter setting for the communication module comprises:

• Inverter parameters which can also be set with the BFVC 904Ckeypad.

• Communication parameters, which can only be accessed via thecommunication module.

Only the inverter parameters are permanently saved in the corresponding inverter.

In the following and in the code table (� appendix B), only the parameters importantfor serial communication are listed. For further information about the parameter settingsee the Manual or the Operating Instructions of the inverters.


4 – 4


4.2 Parameter Sets

4.2 Parameter Sets

The VF–C inverter is equipped with 4 addressable parameter sets. They are addressedby means of a code–digit offset:

• Offset 0 addresses parameter set 1 with the codes C0000 toC1999.




If a parameter is only available once (see VF–CE Operating Instructions), use thecode–digit offset 0.

� Example:

C011 = maximum field frequencyC011 in parameter set 1: code number = 11C011 in parameter set 2: code number = 2011C011 in parameter set 3; code number = 4011C011 in parameter set 4; code number = 6011

Changes of the parameters are automatically saved in the inverter (see VF–CEOperating Instructions). Process data, for instance control words or setpoints, areexcluded.



4.3 Meaning of Individual Parameters


4.3.1 Operating Mode

Code C0001 (operating mode) determines the source (terminal, keypad, LECOM)which writes the frequency setpoint (C0046) and the control word (C0135).

Independently of the selected operating mode C0001, the inverter can be inhibitedunder C0040 via LECOM.

Please note that the operating mode C0001 is available in bothparameter sets. Thus, C0001 must be set identically in both para-meter sets. LECOM control (C0001 = 3) is subject to the operating mode inparameter set1. Terminal control (C0001 <> 3) is subject to theoperating mode in parameters set 1 and parameter set 2.

Tip

4.3.2 LECOM Unit Address (C0009)

The LECOM–A/B protocol uses the LECOM unit address to address the inverter. TheLECOM unit address is set under code C0009 at the inverter. The address must onlybe used once. Thus, each inverter must get its own LECOM unit address. Do not setthe values 00, 10, 20, 30, ..., 90 because they are reserved for group addressing.

The LECOM–A/B protocol enables inverter groups. This allows a write request to beissued to several drives at the same time, e.g. to select new setpoints or enable or inhibitthe inverter. They are selected through the following reserved LECOM unit address:

LECOM unit addressC0009 for group drives

LECOM unit addresses of the addressed inverters

00 all10 11 to 19

20 21 to 29

30 31 to 3940 41 to 49

50 51 to 59

60 61 to 69

70 71 to 7980 81 to 89

90 91 to 99

4 – 6



Please note that with LECOM inverter addresseswhich end with a 0, the inverter does not return anacknowledgement, i.e. the host does not recognizewhether the inverter received the data correctly ornot.

Tip



4.4 Special Features


4.4.1 Start with Inv. Inhibit Instead of QSP

• After mains connection with the operating mode C0001 = 3, thedrive is in the status QSP.

• With C1920 = 1 the switch–on status is always Inv. inhibit, so thatthe drive can be enabled by writing C0040 = 1.

Code Name Note

LECOM format: VD

4.4.2 Reduction of the Response Time of the Interface

• With active reduced response time, write messages (send) are onlychecked for transmission errors:

– If the message is fault–free, a positive acknowledgement(ACK) is sent, otherwise it is a negative acknowledgement(NAK).

– Only then the value to be written is transmitted to theinverter.

• The module can be re–addressed approximately after 50 ms.

The acceptance of the value by the inverter cannot beguaranteed.

4.4.4 Relative Setpoint Selection C0141 (Parameter Channel)

• Enter a relative setpoint which refers to C0011 under C0141.

• Independently of the currently set parameter, C0011 of parameterset 1 is always taken as reference value.

• The automatic adaptation of the relative setpoint in the event of aC0011 change is not considered because C0011 can only bechanged when the inverter is inhibited.

C – 3Matsushita Electric Works (Europe) AG

C.1 LECOM–A/B Protocol


The LECOM–A/B protocol is used to exchange data between NAiS inverters and a host.The LECOM–A/B protocol is based on DIN 66019, ISO 1745 and ANSI X3.28 (category2.5 and A2, A4). These standards are similar to each other and describe the controlmode of a transmission section of a transmission system.

The host, which is the master, can communicate with a NAiS VF–CE frequency inverter(slave) in three modes:

• RECEIVE (� C – 10)

• SEND (� C – 12)

• BROADCAST/MULTICAST (� C – 13)

C.1.1 General

The units communicate by means of the ASCII code:

0 1 2 3 4 5 6 7 8 9 O 6.5 C D E F0 NUL SOH STX ETX EOT ENQ ACK BEL BS HT LF VT jFF CR SO SI

1 DLE DC1 DC2 DC3 DC4 NAK SYN ETB CAN EM SUB ESC FS GS RS US

2 ‘ ’ ‘!’ ‘”’ ‘#’ ‘$’ ‘%’ ‘&’ ‘’’ ‘(’ ‘)’ ‘*’ ‘+’ ‘,’ ‘–’ ‘.’ ‘/’

3 ‘0’ ‘1’ ‘2’ ‘3’ ‘4’ ‘5’ ‘6’ ‘7’ ‘8’ ‘9’ ‘:’ ‘;’ ‘<’ ‘=’ ‘>’ ‘?’

4 ‘@’ ‘A’ ‘B’ ‘C’ ‘D’ ‘E’ ‘F’ ‘G’ ‘H’ ‘I’ ‘J’ ‘K’ ‘L’ ‘M’ ‘N’ ‘O’

5 ‘P’ ‘Q’ ‘R’ ‘S’ ‘T’ ‘U’ ‘V’ ‘W’ ‘X’ ‘Y’ ‘Z’ ‘[’ ‘\’ ‘]’ ‘^’ ‘_’

6 ‘‘’ ‘a’ ‘b’ ‘c’ ‘d’ ‘e’ ‘f’ ‘g’ ‘h’ ‘i’ ‘j’ ‘k’ ‘l’ ‘m’ ‘n’ ‘o’

7 ‘p’ ‘q’ ‘r’ ‘s’ ‘t’ ‘u’ ‘v’ ‘w’ ‘x’ ‘y’ ‘z’ ‘{’ ‘|’ ‘}’ ‘~’

� Example: “EOT” character = 02hex = 2dec

“1” character = 31hex = 49dec

Code number (C1, C2)

Standard addressing

The meaning of the code numbers and the assigned parameters can be obtained fromthe code table (see appendix B). When transmitting data, the code number is coded asfollows:

The following calculation determines the two ASCII digits (value range: 48dec … 127dec)from the code number (value range: 0 … 6229):

C1 = INTEGER((REMAINDER(code number/790))/10)+48dec

� next page


C – 4



C2 = REMAINDER(REMAINDER(code number/790)/10) +INTEGER(code number/790) x 10 + 48dec

The INTEGER is the digit before the comma, the REMAINDER is an integer.

� Example 1: 1/5 = 2 remainder 3

INTEGER(13/5) = 2 REMAINDER(13/5) = 3

� Example 2: Convert code number 1002 in ASCII code C1 and C2:

C1 ASCII = INTEGER((REMAINDER(1002/790))/10) + 48 = INTEGER(212/10) + 48 = 21 + 48 = 69 = 45hex = “E”ASCII

C2 ASCII = REMAINDER(REMAINDER(1002/790)/10) +INTEGER(1002/790) x 10 + 48 = REMAINDER(212/10) + 1 x 10 + 48 = 2 + 10 + 48 = 60 = 3Chex = “<”ASCII

The code number C1002 is converted into the ASCII string “E<”, if it is transmitted to theinverter by a host.

Addressing via code bank

With previous LECOM–A/B drivers, only code numbers in the range from 0 to 255 couldhave been addressed, since these drivers used only one byte as code number. Toachieve the addressing of the wider code–number range with these drivers, use codebanking. The code–number range 0 … 255 is displayed as a window over the wholecode–number range. This is controlled via the code C0249 (code bank). Code C0249can always be accessed via number 249, no matter which code bank has currently beenset.

The following assignments exist:

Code bank Code offset Code–number range0 0 0 … 255

1 250 250 … 505

2 500 500 … 755

3 750 750 … 1005

4 1000 1000 … 1255

5 1250 1250 … 1505

6 1500 1500 … 1755

7 1750 1750 … 2005




�Note

Codebanking is only active when the standard addressing isbeing used. If the selected code numbers are higher than 255,the code–number range increases correspondingly. Only thecorresponding code–number offset is selected by means ofthe code bank.

� Example:

Set the codebank INTEGER (1002/250) = 4 in C0249 to addressthe code number 1002. C1002 is then accessed via the codenumber C02.

Addressing via input selection

Simple LECOM–A/B drivers, which only use the standard addressing, cannot addresssubcodes. The input selection C0248 has been developed to offer the possibility ofaddressing the subcodes. When using the standard addressing, the value entered inC0248 is always considered as subcode. The code C0248 can always be accessed vianumber 248, no matter which code bank has currently been set.

� Example:

Enter value 1 in C0248 to address the JOG value 1 in C0039subcode 1. Now subelement 1 is always addressed whenaccessing C39.

After a subelement has been accessed through C0248,C0248 should be reset to 0 to avoid accidentally addressinga subelement when accessing a code.

Tip

Extended addressing

Another possibility is the direct addressing of parameters by means of extendedaddressing.

! CH1 CH2 CH3 CH4 SC1 SC2

� next page


C – 6



The abbreviations have the following meanings:

! The ASCII character “!” = 21hex = 33dec shows that the expandedaddressing is used.

CH1 to CH4 Code number in hexadecimal code: each character correspondsto a nibble of the code numbers (CH1 is the highest, CH4 is thelowest nibble).

SC1, SC2 Subcode number in hexadecimal code: Each character corres–ponds to a nibble of the code number word (SC1 is the highestand SC2 the lowest nibble).

The following characters can be displayed in the ASCII code:

ASCII 0 1 2 3 4 5 6 7 8 9 O 6.5 C D I F

dec 48 49 50 51 52 53 54 55 56 57 65 66 67 68 69 70

hex 30 31 32 33 34 35 36 37 38 39 41 42 43 44 45 46

A code number range from 0 to 65535 can be addressed by means of these characters.A maximum of 255 subelements (field elements) can be accessed via one subcodenumber of each code.

� Example: 1002 = “!03EA00”

Parameter value (V1 to Vn)

Parameter values can be transmitted in four different formats with the followingstructures:

• ASCII decimal format (VD)

– VK1 VK2 VK3 VK4 VK5 VK6 . NK1 NK2 NK3 NK4

• ASCII hexadecimal format (VH)

H VH1 VH2 VH3 VH4 VH5 VH6 VH7 VH8

• String format (VS)

S VS1 VS2 VS3 VS4 VS5 VS6 ... VS240

• Octet string format for data blocks (VO)

O VO1 VO2 VO3 VO4 VO5 VO6 ... VO240





VK1 to VK6 Integers; decimal point (if required)

NK1 to NK4 Decimal codes (if required)

“H” (48hex) Character [H], transfer of parameter values in the ASCII hexadeci-mal format

VH1 to VH8 1 to 8 hexadecimal characters each [0 to 9; A to F]

“S” (53hex) Character [S], transfer of parameter values in the string format

VS1 to VS240 1 to 12 visible ASCII characters each (no control characters)

“O” (4Fhex) Character [O], transfer of parameter values in the octet stringformat

VO1 to VO240 Data block in hexadecimal code; each character corresponds to anibble of the data block

Parameter value in the ASCII decimal format (VD)

The ASCII decimal format (VD) is most often used. The values consist of the following:

1 leading negative sign(if required) 6 digits before the comma (VK1 to VK6) 1 decimal point (if required) 4 digits after the comma (NK1 to NK4) (if required)

Values from –214748.3648 to 214748.3647 can be displayed.

In the ASCII decimal format (VD), the decimal point mustnot be transmitted if the value does not have digits after thecomma.

Tip

Parameter value in ASCII hexadecimal format (VH)

The LECOM–A/B protocol supports the tranmission of hexadecimal parameter valueswith a length of:

• 2 characters (byte value)

• 4 characters (wort/integer value)

• 8 characters (double word/long integer)

In the ASCII hexadecimal format, VH1 is the highest and VH8 the lowest hexadecimalcharacter.


C – 8



Parameter value in the string format (VS)

By means of the string format (VS) of the protocol it is possible to transmit strings withmax. 20 characters in both directions. The NAiS inverter can only send the string parameters (e. g. C200).

Parameter values in the octet string format (VO)

The LECOM–A/B protocol includes the octet string format (VO) with which it is possibleto transfer data blocks.The character sequence correspond to the filing in the memory (ascending order), i. e.the character transmitted first is the data block nibble with the lowest address. The datastructure of the data block corresponds to the Intel–memory format with the followingdifinition:

BYTE: 1. High nibble

2. Low nibble WORD: 1. High BYTE

2. Low BYTE DWORD: 1. High WORD

2. Low WORD

Unit address (AD1, AD2)

One or more bus participants (slaves) can be selected by means of the unit addresswhich is 2 bytes (AD1, AD2) long. The LECOM–A/B protocol supports the broadcastmessages, i.e. a message is sent to a group or all other bus participants. For this, unitaddresses are reserved (see BROADCAST, page 13). A unit address has the followingstructure:

AD1 AD2


AD1 ASCII ten–digit code of the slave address (0 … 9; 30 … 39hex)

AD2 ASCII one digit code of the slave address (0 … 9; 30 … 39hex)




Block–check character (BCC)

The block–check character (BCC) is used to store the transmitted data and is generatedaccording to DIN 66219 (chapter 3).

Because of the program, the block–check character is generated by a XOR link from thefollowing digits of the SEND message:

• it starts with the character directly after the STX control character

• it ends directly after the ETX control character

– BCC can accept the value 00 … FFhex.

EOT AD1 AD2 STX C1 C2 V1 ... Vn ETX BCC

<——————— BCC ———————>

or with expanded addressing:

STX ”!” CH1 CH2 ... SC2 ETX BCC

<—————————— BCC —————————>

Message response

The NAiS inverter must return an acknowledgement to the host. The only exception isthe broadcast message.This message does not require an acknowledgement.

The NAiS inverter sends two types of acknowledgements:

• Positive acknowledgement (ACK = 06hex), if:

– no faults occur during the block storage (longitudinal andlateral parity),

– a valid command (variable address) has been recognized,

– the variable value is within the permissible range,

– the variable value could have been changed.

• negative acknowlegdement (NAK = 15hex), if:

– one of the above listed conditions cannot be met.

• No acknowledgement, if:

– a broadcast message is send,

– the unit address is not correct.


C – 10



C.1.2 RECEIVE

The command RECEIVE is to request parameter values of the NAiS inverters. The codenumbers of the requested parameter are transmitted with the RECEIVE message usingthe following structure:

EOT AD1 AD2 C1 C2 ENQ


EOT (04hex) End of the (previous) transmission

AD1, AD2 Logic unit address of the slave to be addressed

C1, C2 Code number (two ASCII characters) or extended addressing

ENQ (05hex) Station request

Structure and meaning of the code numbers (C1, C2) and the unit address (AD1, AD2)are described in the corresponding paragraphs of the chapter on SEND (� C – 12).

Message response

The NAiS inverter addressed via a RECEIVE message generates one of the followingresponses:

• The inverter could decode the request and is now sending therequested parameter value to the host.

STX C1 C2 V1 ... Vn ETX BCC

• The inverter could decode the request, however, a check–sum fault(parity fault) occured during transmission.

STX C1 C2 ? ETX BCC

• The inverter could not process the request because the codenumber does not exist.

STX C1 C2 EOT


STX (02hex) Start of text

C1, C2 Code number (two ASCII characters) or extendedaddressing

ETX (03hex) End of text

BCC Block–check character (00 ... FFhex)

? (3Fhex) ASCII character “?”





Structure and meaning of the block–check character (BCC) are described in thecorresponding paragraph of the chapter on SEND (� C – 9).

Examples for a RECEIVE message

� Example 1:

The current speed setpoint (code number C46) is to be read with the bus address 01 atthe inverter.

The host sends the following message:

EOT 0 1 4 6 ENQ

The inverter can response in three different ways:

STX 4 6 3 5 . 4 ETX BCC

Valid request: The current value of the parameter C46 is 35.4 (Hz)

or

STX 4 6 ? ETX BCC

Invalid request: A check–sum fault (parity fault) occured during data transmission

or

STX 4 6 EOT

Invalid request: The parameter C46 does not exist in this inverter.

� Example 2:

The current operating status (code number C68) is to be read with the bus address 25for the inverter. The operating status is bit–coded and transmitted in the hexadecimalformat.

The host sends the following message:

EOT 2 5 6 8 ENQ

The inverter responds:

STX 6 8 H 0 9 0 0 ETX BCC

Valid request: The current value of the parameter C68 is “0900”. This means:

C.1.3 SEND

The command SEND is to transmit data from the master to the slave. The master sendsa message with the following structure:

EOT AD1 AD2 STX C1 C2 V1 ... Vn ETX BCC



AD1, AD2 Logic unit address of the slave to be addressed

STX (02hex) Start of text

C1, C2 Code number (two ASCII characters)

V1 to Vn Parameter value (n ASCII characters)

ETX (03hex) End of text

BCC Block–check character (00 ... FFhex)

In the text section of the message, which is embedded between the control charactersSTX and ETX, the code number (C1, C2) and the corresponding parameter value (V1to Vn) are transmitted to the slave.

� Example: SEND message

The maximum speed (code number C11) is to be set to the value 95.2 Hz via the busaddress 34 at the inverter.

The host must send the following SEND message:

EOT 3 4 STX 1 1 9 5 . 2 ETX BCC




The inverter can respond with two different acknowledgements:

ACK

The command could not be processed correctly. The current value of the parameter C11is 95.2 Hz

or

NAK

The request could not been processed correctly. The parameter value was not changed.

C.1.4 BROADCAST/MULTICAST

In a bus network, the command BROADCAST is to address all participants or a groupof participants (multicast) at the same time. The structure of the BROADCAST messageis similar to the structure of the SEND message. The only exception is that it does notreturn an acknowledgement.

The participants can be selected via their unit addresses. The following unit addressesare reserved for a BROADCAST message:

Unit addresses Unit address of ASCII character(reserved) groups AD1 AD2

00 all “0” “0”

10 11 to 19 “1” “0”

20 21 to 29 “2” “0”

30 31 to 39 “3” “0”

40 41 to 49 “4” “0”

50 51 to 59 “5” “0”

60 61 to 69 “6” “0”

70 71 to 79 “7” “0”

80 81 to 89 “8” “0”

90 91 to 99 “9” “0”

� Example: BROADCAST message

All inverters are to be stopped when setting inverter enable (code number C40 = 0).

The host sends the following BROADCAST message:

EOT 0 0 STX 4 0 0 ETX BCC

The inverters do not return an acknowledgement.


C – 14



C.1.5 Monitoring of the Slave Response

The master monitors the selected slave. The slave must return a response within adefined time.Under the following circumstances the slave does not return a response tothe master (time out):

• The unit address could not be recognized

• A fault (e.g. parity fault) had been detected in one or severalcharacters, including the character ”ENQ”

• The transmission path is faulty

• A BROADCAST message had been sent

• The hardware does not work properly

If the master does not receive a response within a defined period of time, thetransmission is tried again. The number of repetitions is limited.

The monitoring time of the master should be approx. twice as long as the maximumrespond time.

C.1.6 Transmission Faults

After a transmission fault, the master can read C0068 and evaluate the communicationerror in bit 4…7 .
