Example 14: programmable zero speed window

Assume you want the value of the main analogue reference to remain below a

programmable threshold when it is cancelled. In practice, a speed window around zero rpm is

defined within which speed is set to zero. The value of the threshold is set in parameter Pr88

in rpm; parameter Pr89 is used as an auxiliary memory area.

The required pico-PLC program is as follows:

Browse...button. The following installation procedure automatically creates a new icon for

Pcbrush. Once the program is installed, launch it by double clicking the relative icon (or select

the icon and then press ENTER).

Set the following parameters on the drive: Pr26=6, Pr27=0, b40.14=1, b42.3=1.

• Windows and the Windows logo are registered trade marks or trade marks owned by Microsoft Corporation in the United States of

America and/or other countries.

5. SERIAL INTERFACE

The drive communication protocol is “master-slave” half-duplex type on an asynchronous

RS-485/RS-422 line. The drives assume control of the line only following interrogation by

the master.

Up to 32 drives can be connected on the same serial line, allocating each a different serial

address in parameter Pr27. It is also possible to set transmission speed in parameter Pr26 as

specified in the table:

Pr26 (decimal base)

b/s

time-out (ms)

600

512

1200

256

2400

4800

9600 (*)

9600

19200

38400

57600

125000

57600 (**)

(*) The version with code Pr26=4 differs from Pr26=5 because of the 25 ms response delay.

This version was developed to interface with PLCs that require this characteristic.

(**) The version with code Pr26=10 was developed to allow data communication between

two HPD drives.

Refer to the heading Serial line connection for connection diagrams.

5.1. Communication protocol

The right hand column in the table shows the time-out value in milliseconds for each

communication speed; this is the time, starting from the beginning of each message (STX)

within which the transmission of the message must terminate. Therefore, if the message is

interrupted, after the time-out the drive will ignore the information already received and stand

by to receive a new message.

Messages are made up of several consecutive data in the following format:

1 start bit

8 data bits following one byte between square brackets

1 parity bit (even)

1 stop bit

The message structure is:

[STX] [CMD+ADDR] [LUN] [PAR] [D0] ... [Dn] [CHK]

where:

[STX] = $7E transmission start indicator. If a field other than STX should assume the value

$7E in the message, this field is followed by a ($00) to ensure that it cannot be interpreted as

an [STX].

[CMD+ADDR] = command and address of peripheral device, always different to zero. This

datum is composed as follows: the first 5 bits (from 0 to 4) define the drive address (from 0 to

31); the remaining 3 bits (from 5 to 7) define the type of message, as described in the

following table:

CMD bit 7 bit 6 bit 5 message type

drive response

read PLC instruction

write PLC instruction

read parameter

write parameter

bit change

broadcast parameters to all drives

[LUN] = total number of bytes transmitted (parameter or PLC instruction); can assume values

from 1 to 4. This value must not hold zero characters ($00) after values that coincide with the

initial transmission character ($7E).

[PAR] = parameter or PLC instruction read/write address

[D0] ... [Dn] = datum transmitted.

[CHK] = 256 modulus sum of all fields except [STX] (checksum).

Message types

[CMD1] = drive response to data request, format:

[STX] [001+ADDR] [LUN] [PAR] [D0] ... [Dn] [CHK]

or confirm message in response to data entry or update, format:

[STX] [001+ADDR]

where ADDR identifies the answering drive.

[CMD2] = read message of PLC area instruction; format:

[STX] [010+ADDR] [LUN] [PAR] [CHK]

[CMD3] = write message of PLC area instruction; format:

[STX] [011+ADDR] [LUN] [PAR] [D0] ... [Dn] [CHK]

[CMD4] = parameter read message; format:

[STX] [100+ADDR] [LUN] [PAR] [CHK]

[CMD5] = parameter write message; format:

[STX] [101+ADDR] [LUN] [PAR] [D0] ... [Dn] [CHK]

[CMD6] = byte parameter bit change message; format:

[STX] [110+ADDR] [LUN] [PAR] [D0] [D1] [CHK]

In this case (LUN=2) two bytes are transmitted for the data: the first byte is the mask

containing 0 in the positions of the bits to change and 1 in the other positions; the second byte

contains 1 in bit positions to be set to 1 and 0 in the other positions. The address PAR

corresponds to the parameter (byte) in which one or more bits is to be modified. If the

parameter is a word and the bit to be modified is among the first 8 (b0...b7): PAR

parameter address; otherwise if the bit to modify is one of the upper 8 (b8...b15): PAR =

parameter address + 1.

[CMD7] = parameter write broadcast message to all drives connected to the serial line;

format:

[STX] [11100000] [LUN] [PAR] [D0] ... [Dn] [CHK]

The address of peripheral device (ADDR) must be zero.

Notes:

- Parameters shown on the display with decimals must be treated as integer values, e.g.

978.5 will be read, and written, as 9785.

- All values preceded by the symbol $ are hexadecimal numbers.

- The value in square brackets is the basic unit (byte) of the message.

- To be considered valid all messages must be terminated within a clearly defined time

interval (time-out) which is a function of speed, and they must have correct parity and

checksum.

- The drive responds to data requests or transmission only if the message is received

correctly; if the message contains an error, no answer will be transmitted. The only

exception is message type 7, with which a datum is transmitted with a single message

addressed to all drives connected to the serial line.

Serial line initialisation and management

Drive serial communication can be enabled or disabled by means of bit b40.14.

The drive is factory set with b40.14=0, i.e. serial line disabled (default).

If you want to use the serial line first set the baud-rate in Pr.26; now set the serial address

in Pr.27; finally, enable serial communication by setting b40.14=1 and initialise using b42.3.

At this point you must save the configuration using command b99.15.

For parameter addresses and lengths refer to the relative table.

In the case of PLC instructions, each one occupies 2 or 4 bytes, the format of which is

described below.

Instruction

code

length (bytes)

LD Pa.y

LDN Pa.y

OUT Pa.y

OUTN Pa.y

AND Pa.y

ANDN Pa.y

OR Pa.y

ORN Pa.y

ADD Pa, Pb, Pc

SUB Pa, Pb, Pc

MUL Pa, Pb, Pc

DIV Pa, Pb, Pc

SET Pa.y

RES Pa.y

FIN Pb40.y/Pb70.y

END

The memory area available for PLC instructions is 128 bytes, with addresses from 0h to 7Fh.

As the minimum length for each instruction is 2 bytes, the PLC program can hold a

maximum of 64 instructions.

The first four bits of the first byte in each instruction (b0..b3) contain the instruction code.

For the first 8 instructions in the table (LD...ORN) and the SET and RES instructions, the

remaining 4 bits of the first byte (b4..b7) contain the value y, while the second byte contains

the value Pa.

For instructions ADD, SUB, MUL and DIV, the second byte contains the value Pa, the

third Pb, and the fourth Pc.

The second byte is not utilised for the END instruction.

For the FIN instruction the fifth bit (b4) of the first byte selects the parameter: b4=0 refers

to Pr.40, b4=1 refers to Pr.70; the sixth bit (b5) of the first byte is used for negative logic if

required: b5=0 the bit is copied; b5=1 the bit is inverted and then copied. The second byte of

the FIN instruction contains the value of y.

If FIN instructions are used they must be the first of the program and there must be no

more than 3 so they will occupy addresses from 0h to 5h. If a FIN instruction is included from

address 6h forward or, anyway, after any other instruction, it will be ignored (NOP).

The instructions must be one after the other starting from address 0h, without any free bytes.

There is just one program and it terminates with the END instruction.

Serial line application examples

For a better understanding of how to implement the serial line communication protocol, we

have provided a few examples for each type of message.

The values are entered simply by way of example.

Case 1: reading a 1 byte parameter

Assume you want to read the value of parameter Pr.31 (operating mode), and that the value of

this parameter is 9; assume the drive serial address is 0. The message to transmit is:

[$7E][$80][$01][$54][$D5]

The drive answers with the message:

[$7E][$20][$01][$54][$09][$7E][$00]

Case 2: reading a 2 byte parameter

Assume you wish to read the reference speed (Pr.7) and that the relative value is 2000;

assume also that the drive serial address is 1. The message to transmit is:

[$7E][$81][$02][$42][$C5]

The drive answers with:

[$7E][$21][$02][$42][$D0][$07][$3C]

Case 3: writing a 1 byte parameter

Assume you want to select operating mode 1 (Pr.31); assume also that the drive serial address

is 3. The message to transmit is:

[$7E][$A3][$01][$54][$01][$F9]

The drive answers with:

[$7E][$23]

Case 4: writing a 2 byte parameter

Assume you intend to set rated current at 25.3% (Pr.33); assume also that the drive serial

address is 3. The message to transmit is:

[$7E][$A3][$02][$C6][$FD][$00][$68]

The drive answers with:

[$7E][$23]

Case 5: setting a bit to 1

Assume you want to enter the command to save the PLC program (b99.14=1); assume also

that the drive serial address is 0. The message to transmit is:

[$7E][$C0][$02][$93][$BF][$40][$54]

The drive answers with:

[$7E][$20]

Case 6: setting a bit to 0

Assume you want to disable the drive by software (b40.9=0); assume that drive serial address

is 0. The message to transmit is:

[$7E][$C0][$02][$5D][$FD][$00][$1C]

The drive answers with:

[$7E][$20]

Case 7: writing a PLC instruction

Assume you want to set the first PLC instruction as: LD 90.4; assume the drive serial address

is 0. The message to transmit is:

[$7E][$60][$02][$00][$40][$5A][$FC]

The drive answers with:

[$7E][$20]

Case 8: reading the first PLC instructions

Assume you want to read the first instructions of the PLC default program; assume the serial

address of the drive is 0. The message to transmit is:

[$7E][$40][$04][$00][$44]

The drive answers with the message:

[$7E][$20][$04][$00][$10][$5A][$A7][$5A][$8F]

which corresponds to the acquisition of the following instructions: LD 90.1, ORN 90.10.

The Profibus-DP interface is optional, and must therefore be expressly requested when ordering the

EC-4 board.

The Profibus interface implemented is based on the ASIC LSPM2. The EC-4 is seen by the profibus

master as a remote I/O module with 16 inputs and 16 outputs. Obviously, the I/Os are virtual.

Interpretation of the meaning of the I/Os will be defined by the program installed on the EC-4

board.

The configuration file SBC0EC4.GSD is provided to configure the EC-4 as a slave Profibus-DP.

n.c.

Two application layers are available for the Can interface.

The first is SBCCAN, which enables master/slave communication, as well as slave/slave

communication. It includes synchronism telegrams, transmissions to slave groups, and cyclic,

acyclic, and interrupt transmissions. There is also a subset of SBCCAN which allows for simple

data exchange between SBC drives (IDC inter-drive communication).

The second is DeviceNet. With the DeviceNet interface implemented, the EC-4 is seen by the master

as a remote I/O module with 256 inputs and 256 outputs. Obviously, the I/Os are virtual.

Interpretation of the meaning of the I/Os will be defined by the program installed on the EC-4

board.
