1. General outlines of the communication function

This manual explains the RS485 communications interface function provided for the TOSVERT

VF-S15 series of industrial inverters.

The TOSVERT VF-S15 series of inverters can be connected to a computer or a controller (hereinafter referred to as the computer) for data communications via USB converter (USB001Z).

By writing computer programs, you can monitor the operating status of the inverter, control its operation in various ways from the computer, and change and store parameter settings on storage devices.

The communication protocol is preparing the Toshiba inverter protocol and the Modbus RTU protocol. Please choose selection of a protocol with a communication protocol selection parameter

().

<Computer link>

By preparing the program (explained later), the following information can be exchanged between the computer and the inverter.

 Monitoring function (used to monitor the operating status of the inverter: Output frequency, current, voltage, etc.)

 Command function (used to issue run, stop and other commands to the inverter)

 Parameter function (used to set parameters and read their settings)

As for data communications codes, the TOSVERT VF-S15 series of inverters support the binary

(HEX) code, in addition to the JIS (ASCII) code. The communications function is designed on the assumption that the JIS (ASCII) code is used for communications between the inverter and the personal computer, and the binary (HEX) code for communications between the inverter and the microcomputer built into the controller. A communication number is used to access the desired data item.

* The smallest unit of information that computers handle is called a “bit (binary digit),” which represents the two numbers in the binary system: 1 or 0. A group of 16 bits is referred to as a “word,” which is the basic unit of information the VF-S15 series of inverters use for data communications.

One word can handle data items of 0 to FFFFH in hexadecimal notation (or 0 to 65535 in decimal notation).

3. Communication protocol

VF-S15 supports the Toshiba inverter protocol and a part of Modbus RTU protocol.

Select the desired protocol from in the following communication protocol selection parameters

(f829).

“Parameter Name f829, Communication Number. 0829”

Data Range: 0, 1 (Initial value: 0)

0: Toshiba inverter protocol (Includes inter-drive communication)

1: Modbus RTU protocol

* A parameter change is reflected when the inverter is reset, such as in power off.

3.1. About the handling of received frames

To send and receive data frames, a frame synchronization system for locating the start and end points of each frame is defined with time for which no data is sent (time interval equivalent to the time required to send 3.5 bytes of data).

If no data is sent for the time required to send 3.5 bytes of data at the current transmission speed

(approx. 4 ms or more at 9,600 bps or approx. 2 ms or more at 19,200 or approx. 1 ms or more at

38400) after receipt of a frame, the entire frame is assumed to have reached and information in it is analyzed. For this reason, an interval corresponding to at least 3.5 bytes of data must be placed between frames.

When two or more inverters on the same line are controlled individually one after another, the data flames are not only data from the computer to an inverter but also the response from an inverter to the computer. Therefore, an interval corresponding to at least 3.5 bytes should be placed between the time when the computer receives a response from an inverter and the time when it sends a frame to the next inverter. Otherwise the return frame received and the frame that is sent immediately after receipt of the return frame will be recognized as one frame and communication will not be carried out normally.

[Correct]

Frame A

Fram e A (1/2) Frame A (2/2)

Frame B

3.5 bytes or more

Note: An inverter cannot receive frame

B before it finishes analyzing the contents of frame A.

[Wrong]

If divided into two smaller frames, frame A cannot be received as a single fram e when the interval corresponds to less than 1.5 bytes of data.

Frame B

3.5 bytes or more

E6581913

4. Toshiba inverter protocol

Select “TOSHIBA” (f829=0) in the communication protocol selection parameters. “TOSHIBA”

(f829=0) is set for initial communication protocol selection of shipment setting. (See “3.

Communication protocol”.)

 Exchange of data between the computer and the inverter

In communication between the computer and the VF-S15 (hereinafter referred to as the inverter), the inverter is always placed in wait states and acts as a slave that operates on a request from the computer.

The judgment of ASCII mode or binary mode is automatically made with the start code.

ASCII mode

Binary mode

Start code

“(”

“2FH(/) ”

“CR” (carriage return)

Required

Not required

(1) If there is no transmission format or the inverter number that matches, an error occurs and no response is returned.

(2) When an inverter number is added behind the “(” communication will take place only in case of broadcast communication or if the number matches up with that assigned to the inverters.

(3) When a time-out period is specified with parameter f803 (communication time-out time), a time-out occurs if communication do not terminate normally within the specified time. With parameter f804 (communication time-out action), you can specify what the inverter should do if

a time-out occurs. For details, refer to Section 7.3.

(4) On executing the command received, the inverter returns data to the computer. For the response time, see Appendix 2, “Response time”.

Note:

Communication is not available for about one second (initialization) just after the power is supplied to the inverter. If the control power is shut down due to an instantaneous voltage drop, communication is temporarily interrupted.

4.1.3. Transmission format of Block Communication

What is block communication?

Data can be written in and read from several data groups set in one communication by setting the type of data desired for communication in the block communication parameters (f870, f871, f875

to f879) in advance. Block communication can save the communication time.

Data is transmitted hexadecimal using the binary (HEX) code transmission characters. “Computer

→ inverter” is for writing only, while “Inverter → computer” for reply is for reading only.

4.2. Commands

Here are the communication commands available.

Command Function

W command Writes the data with the specified communication number. (RAM and EEPROM).

P command Writes the data with the specified communication number. (RAM).

R command Reads the data with the specified communication number.

G command

Reads the data with the specified communication number. (For binary mode only.

Dummy data is required for this command.)

S command Inter-drive communication command (For binary mode only.)

X command Block communication (Computer -> Inverter)

Y command Block communication (Inverter -> Computer)

W (57

H

)

(RAM

*1

/EEPROM

*2

write)

Mandatory action

This command is used to write new data into the parameter specified using it communication number. It writes data into the RAM and EEPROM. For parameters whose settings cannot be stored in the EEPROM (e.g., parameter with the communication number FA00), the W (57H) command writes data into the RAM only. It cannot be used to write data into read-only parameters (e.g., parameter with the communication number FD?? or FE??).

Each time an attempt to write data is made, the inverter checks if the data falls within the specified range. If this check reveals that the data falls outside the specified range, the inverter will reject it and return an error code.

- Ex.: Setting the deceleration time (communication number: 0010) to 10 sec.

CAUTION

 Do not write the same parameter to the EEPROM more than 10,000 times. The life time of EEPROM is

approximately 10,000 times.(Some parameters are not limited, please refer to the “9. Parameter data“)

The lifetime of EEPROM is approximately 10,000 times. When using the Toshiba inverter protocol and the data does not need to be records, use P command (the data is written only to RAM).

 Explanation of terms

*1: The RAM is used to temporarily store inverter operation data. Data stored in the RAM is cleared when the inverter is turned off, and data stored in the EEPROM is copied to the RAM when the inverter is turned back on.

*2: The EEPROM is used to store inverter operation parameter settings, and so on. Data stored in the EEPROM is retained even after the power is turned off, and it is copied to the RAM when the inverter is turned on or reset.

write)

This command is used to rewrite data into the parameter specified using a communication number.

It writes data into the RAM only. It cannot be used to write data into any read-only parameters. Each time an attempt to write data is made the inverter checks whether the data falls within the specified range. If this check reveals that the data falls outside the range, the inverter will reject it and return an error code.

To use the “G” command, however, dummy data (2 bytes) is needed.

This command is available only in binary mode.

Inter-drive communication command(RAM

*1

Write)

This command is for using frequency command value in % (1 = 0.01%), instead of in Hz, and is for synchronous-proportional operation in inter-drive communication. This command can also be used in ordinary computer link communications.

When writing in the frequency command value (FA01) is enabled and a parameter other than it is specified, a communication number error will result. Data is written in the RAMs only and at this time the data check such as an upper limit and lower limit checking is not carried out.

Data is not returned from the inverters while this command is used. This command can be used only in the binary mode.

For the details of the format, see “6.2. Transmission format for inter-drive communication”.

Use (%) as the unit for frequency command value specified by the command S, instead of (Hz), and the receiving side converts units for frequency values to “Hz” in accordance with the point conversion parameter. The conversion formula is shown below.

Frequency command value (Hz) =

Point 2 frequency (F813) − Point 1 frequency (F812)

Point 2 (F814) − Point 1 (F811)

− Point 1 (F811)) + Point 1 frequency (F812) x (Frequency command value (%)

18

E6581913

When Command “s” (lowercase letter) is received, the slave side judges that the master side is tripped and operates in accordance with the inter-drive communication parameter ().

For detail, see "7. Communication parameters".

E6581913

4.4. Broadcast communication function

Broadcast communication function can transmit the command (write the data) to multiple inverters by one communication. Only the write (W, P) command is valid and the read (R, G) command is invalid. The inverters subject to the broadcast communication are the same to the independent communication; 0 to 99 (00H - 63H) in the ASCII mode, and 0 to 63 (00H - 3FH) in the binary mode.

To avoid data deforming, the inverters to return data will be limited.

 “Overall” broadcast communication (ASCII mode / Binary mode)

- ASCII Mode

If you enter two asterisks (**) in the inverter number position of the data transmission format, the computer will send the data simultaneously to all inverters (with an inverter number between 0 and

99 (00 to 63H)) on the network.

- Binary Mode

To put "FF" to the specified place of the inverter number in the communication format validates the broadcast communication and the command is transmitted to all the applicable inverters in the network (inverter numbers from 0 to 63 (00 to 3FH)).

<Inverter that returns data to the computer>

Data is returned from the inverter bearing the inverter number 00 only.

If you do not want inverters to return data, do not assign the number 00 to any inverter on the network.

 “Group” broadcast communication (ASCII mode only)

If you put “*?” in the inverter number position of the data transmission format, data will be sent simultaneously to all inverters bearing a number whose digit in the one’s place in decimal notation is”?”

If you put ”?*” in the inverter number position of the data transmission format, the data will be sent simultaneously to all inverters bearing a number whose digit in the ten’s place in decimal notation is”?”.

(“?”: Any number between 0 and 9.)

<Inverter that returns data to the computer>

Data is returned only from the inverter bearing the smallest number in the same group of inverters

(i.e., inverter whose number in the position of ”*” is 0).

If you do not want inverters to return data to the computer, do not assign a number having a 0 in the position of “*” to any inverter on the network.)

 Examples of broadcast communication

Ex: Set the frequency setting for communication to 60Hz.

Example of transmission of data from computer to inverter: (**PFA011770)

CR

Example of data returned from inverter to computer: (00PFA011770)

Data is returned from the inverter numbered 00 only, while commands are issued to all inverters connected to the network.

CR

Example of data returned from inverter to computer: (09PFA011770)

Data is returned only the inverter numbered 09 only, while commands are issued to a maximum of 10 inverters bearing the number 09, 19, 29, 39, ... or 99.

*1: Error signal I/F

In broadcast communication, only the representative inverter in each block returns data to the computer. However, you can make the representative inverter in each block report the occurrence of a problem in the block. To do so, follow these steps.

Set the timer function so that, if a time-out occurs, the inverter will trip (Ex.: f803=3 (sec)), set the output terminal selection parameter (FL) so that trip information will be output through the output terminal (f132=10), and set the input terminal selection parameter (F) of the representative inverter in each block to “external input trip (emergency stop)” (f111=20, 21(Inversion)). Then, connect the input terminal (F, CC) of the representative inverter to the FL terminal (FLA, FLC) of each of the other inverters in the same block. In this setting, if an inverter trips, the representative inverter will come to an emergency stop, and as a result it will report the occurrence of a problem in its block to the computer. (If the representative inverter returns a lowercase letter in response to a command from the computer, the computer will judge that a problem has arisen in an inverter.) To examine details on the problem that has arisen, the computer accesses each individual inverter, specifying its communication number. To make the computer issue a command to all inverters in block 1 or block 2 shown in the figure above, specify “1*” or “2*”, respectively. In this system, inverter No. 10 will return data to the computer if a problem arises in block 1, or inverter No. 20 if a problem arises in block 2. For overall broadcast communication, specify “**”, in which case the inverter with the communication number “00” will return data to the computer.

In this example, if you want the computer to maintain communication without bringing an representative inverter to an emergency stop, set its input terminal selection parameter to “disabled

(f111=0) but not to “external input trip (emergency stop).” This setting causes the computer to check the setting of the input terminal information parameter (Communication No.=FE06, bit 0) of the representative inverter, and as a result enables the computer to detect the occurrence of a problem.

CAUTION:

Data from inverters will be deformed if inverters of the same number are connected on the network.

Never assign same single numbers to inverters on the network.

5. Modbus RTU protocol

The Modbus RTU protocol of VF-S15 supports only part of the Modbus RTU protocol. All data will be binary codes.

 Parameter Setting

 Protocol selection (f829)

Select “Modbus RTU (f829 = 1) in the communication selection parameters. “TOSHIBA”

(f829=0) is set for communication protocol selection in initial shipment setting. (See “3. Com-

munication protocol”.)

 Inverter number ( f802

)

Inverter numbers. 0 to 247 can be specified in the Modbus RTU. “0” is allocated to broadcast communication (no return). Set between 1 and 247.

<Related Parameter: Change and set as necessary> f800

: Baud rate f801

: Parity

 Data Exchange with Inverters

The inverters are always ready to receive messages and perform slave operation in response to computer requests.

A transmission error will result if the transmission format does not match. The inverters will not respond if a framing error, parity error, CRC error or an inverter number mismatch occurs. If no response is received, the computer side recognizes that a communication error has occurred.

Transmit data again.

(1) In case spacing for more than 3.5 bytes are provided before characters, all data immediately

preceding it will be aborted. (See “3.1. About the handling of received frames”.)

(2) Communication will be effective only when inverter numbers match or the communication mode is 0 (Broadcast communication). If there is no inverter number that matches or 0 (broadcast communication) is specified, no response is returned by any inverter.

(4) On executing the command received, the inverter returns data to the computer. For the response time, see Appendix 2, “Response time”.

(3) If no communication take place within the time specified using the timer function, the computer will assume that a communication error has occurred and trip the inverter. The timer function is

disabled when the inverter is turned on or initialized. For details, see “7.3. Communication

time-out detection”.

 Caution:

Communication is not possible for about one second after the power is supplied to the inverter until the initial setting is completed. If the control power is shut down due to an instantaneous voltage drop, communication is temporarily interrupted.

5.2. CRC Generation

“CRC” is a system to check errors in communication frames during data transmission. CRC is composed of two bytes and has hexadecimal-bit binary values. CRC values are generated by the transmission side that adds CRC to messages. The receiving side regenerates CRC of received messages and compares generation results of CRC regeneration with CRC values actually received. If values do not match, data will be aborted.

End (Return CRC)

A procedure for generating a CRC is:

1, Load a 16–bit register with FFFF hex (all 1’s). Call this the CRC register.

2. Exclusive OR the first 8–bit byte of the message with the low–order byte of the 16–bit CRC register, putting the result in the CRC register.

3. Shift the CRC register one bit to the right (toward the

LSB), zero–filling the MSB. Extract and examine the

LSB.

4. (If the LSB was 0): Repeat Step 3 (another shift).

(If the LSB was 1): Exclusive OR the CRC register with the polynomial value A001 hex (1010 0000 0000 0001).

5. Repeat Steps 3 and 4 until 8 shifts have been performed. When this is done, a complete 8–bit byte will have been processed.

6. Repeat Steps 2 through 5 for the next 8–bit byte of the message. Continue doing this until all bytes have been processed.

7. The final contents of the CRC register is the CRC value.

8. When the CRC is placed into the message, its upper and lower bytes must be swapped as described below.

6. Inter-drive communication

Inter-drive communication (communication between inverters) are used, for example, when performing speed proportional control of two or more inverters without using a PLC or computer. The command is instructed by the operation from the master inverter’s panel or analog input, etc.

With the Inter-drive communication function, the master inverter continues to transmit the data selected by the parameters to all the slave inverters on the same network. The master inverter uses the S command for outputting instructions to the slave inverters, and the slave inverters do not re-

turn the data. (See “4.2. Commands".) Network construction for a simple synchronized operation

and speed-proportional operation can be created by this function.

* If the master inverter trips, the slave inverters display the blinking error code “t” and come to a full stop (0Hz).

After the master inverter was reset, the blinking error code “t” is lost.

* With the communication time-out parameters f803 and f804, you can specify what the slave inverters should do (continue to operate, issue an alarm or trip) if a cable is broken or the master inverter is turned off during operation.

* To use the inter-drive communication function, select “Toshiba inverter protocol” ( =) in the communication protocol selection parameters. “Toshiba inverter protocol” (=) is

set for communication protocol selection in Shipment setting. (See “3. Communication proto-

col”.)

Speed command can be transmitted but the run / stop signal is not issued. Slave station should have an individual stop signal or the function to stop the action by the frequency reference. (Setting is necessary for f241:

Operation start frequency, f242: Operation start frequency hysteresis.)

For continuing the operation by the last received command value in the case of a communication breakdown, communications time-out time (f803) to trip the slave inverters. The master inverter does not trip even though the communication breakdown happens. To trip the master inverter, provide an interlock mechanism by installing an FL fault relay point or the like from the slave side.

E6581913

 Setting of parameter

●Protocol selection (f829) Shipment setting: 0 (TOSHIBA)

Protocol setting with all inverters (both master and slave inverters) engaged in inter-drive communication

0: Set the TOSHIBA.

* Inter-drive communication are disabled when Modbus RTU protocol is selected.

* This parameter is validated after resetting the inverter or rebooting the power supply.

● Setting of master and slave inverters for communication between inverters (setting of master and slave) (f806) ... Shipment setting = 0

Assign one master inverter in the network. Other inverters should be the slave inverters.

*Specify only one inverter as the master. In case two or more inverters are designated for the master inverter in the same network, data will collide.

- Setting to the master inverter

Set data desired for sending from the master side to the slave side.

3

: Master (transmission of frequency commands)

4

: Master (transmission of output frequency signals)

- Setting to the slave inverters

Set the desired action on the slave side that will be needed when the master trips.

0 : Slave (0 Hz command issued in case the master inverter fails)

(The output frequency is limited to the lower limit frequency.)

1 : Slave (Operation continued in case the master inverter fails)

Note: If the master inverter trips when an output frequency is specified for it, the operation frequency of the slave inverters become 0Hz because tripping of the master inverter causes its output frequency to drop to 0Hz.

2 : Slave (Emergency stop tripping in case the master inverter fails)

The way they make an emergency stop depends on the setting of f603 (emergency stop).

*This parameter is validated after resetting the inverter or rebooting the power supply.

 Communication waiting time (f805) ... Shipment setting = 0.00

- Setting to the master inverter

Specify a waiting time if you want the master to issue commands to slaves with a given delay.

● Frequency setting mode selection 1 (fm0d) ・・・ Shipment setting = 0: Setting dial 1

Designate a target of speed command input for the inverter to the parameter fmod.

- Setting to the master inverter

Select except RS485 communication (fm0d≠4).

- Setting to the slave inverters

Select RS485 communication (fm0d=4)

E6581913

 Relating communication parameters

Following parameters should be set or changed if necessary.

 Baud rate (f800)... Shipment setting = 4: 19200bps

Baud rate of all inverters in the network (master and slave) should be same network.

 Parity (f801) ... Shipment setting = 1: Even parity

Parity of all inverters in the network (master and slave) should be same network.

 Communication time-out time (f803) ... Shipment setting = 0.0

Operation is continued by the last received command value in the case of a communication breakdown. To stop the operation of inverter, provide a communication time-out time (ex. f803=1.0

second

) to the slave inverters. The master inverter does not trip even though the communication breakdown happens. To trip the master inverter, provide an interlock mechanism by installing a FL fault relay point or the like from the slave side.

 Frequency point selection (f810, f811-f814)

The command from master inveter can be performed by the parameter of the point setting.

See “6.1 Speed proportional control” for details.

6.1. Speed proportional control

Proportional control of frequency can be performed in two ways: control by selecting frequency points and control by adjusting the ratio to the maximum frequency. This section explains proportional control of inverters by means of a master inverter (inter-drive communication), although the

VF-S15 series inverters are ready for proportional control by means of the “S” command even when they are operated under the control of a computer (computer-linked communication) (in the latter cases, read the master inverter as the computer).

Proportional control can also be performed in units of Hz using ordinary write commands (W and P commands) (frequency point selection only). For proportional control in units of %, however, the S command should be used.

* For proportional control by selecting frequency points, the gradient can be set variously according to the way each inverter is used. For proportional control by controlling the ratio to the maximum frequency, settings can be made easily without consideration of the rate at which the frequency is increased or decreased to the target frequency.

7. Communication parameters

7.1. Baud rate (f800), Parity (f801)

Communication baud rate and parity bit should be uniform inside the same network.

This parameter is validated by resetting the power supply.

7.2. Inverter number (f802)

This parameter sets individual numbers with the inverters.

Inverter numbers should not be duplicated inside the same network.

Receiving data will be canceled if inverter numbers specified in individual communication and set by a parameter do not match.

This parameter is validated from the communication after change

Data range: 0 to 247 (Initial value: 0)

Parameters can be selected between 0 and 247. Note that the communication protocols limit inverter numbers as follows:

● Toshiba inverter protocol ASCII mode: 0 to 99

● Toshiba inverter protocol Binary mode: 0 to 63

● Modbus RTU protocol: 0 to 247 (0: Broadcast communication)

49

E6581913

7.3. Communication time-out detection (f803) (f804) (f808)

The timer function is mainly used to detect a break in a cable during communication, and if no data is sent to an inverter within the preset time, this function makes the inverter trip () or issue an alarm (). With the communication time-out action parameter (), you can specify what the inverter should do (trip, issue an alarm or do nothing) if a time-out occurs.

 How to set the timer

By default, the communication time-out time parameter (f803) is set to 0.0 (Disabled).

* Timer adjustment range

0.1 sec. (01H) to 100.0 sec. (3E8H) / Timer off is 0.0 sec.

 How to start the timer

If the timer is set from the operation panel, it will start automatically the instant when communication is established for the first time after the setting.

If the timer is set from the computer, it will start automatically the instant when communication is established after the setting.

If the timer setting is stored in the EEPROM, the timer will start when communication is established for the first time after the power has been turned on.

Note that, if the inverter number does not match or if a format error occurs, preventing the inverter from returning data, the timer function will assume that no communication has taken place and will not start.

 How to specify what an inverter should do if a time-out occurs

By default, the communication time-out action parameter (f804) is set to 0 (Alarm only). The data of 1 is trip (err5) and coast stop. The data of 2 is trip (err5) after deceleration stop.

 Time-out detection condition

By default, the communication Time-out detection (f808) is set to 1 (When communication

-mode is selected).

When it is set to 0, it always detects time-out error.

When it is set to 2, it detects time-out error during communication-mode and running.

 How to disable the timer

Set 0.0 (Disabled) to the parameter (f803).

Ex.: To disable the timer function from the computer (To store the timer setting in the EEPROM)

E6581913

7.4. Communication waiting time (f805)

Use this function for the following case:

When the data response from the inverter is too quick after the PC had sent the data to the inverter,

PC process cannot get ready to receive the data, or when the USB/RS485, RS485/RS232C converter is used, changeover of sending and receiving data takes much time in the converter process.

Functional specification:

A time for sending data is prolonged longer than the preset time (f805), until the inverter returns the data to the PC, after it finishes receiving the data (in case of an inter-drive communication, until the inverter returns the next data to the PC, after it has sent the data.) In case the inverter's processing capacity requires longer setting time, the value more than this time will be the set value. (The parameter makes the inverter wait for more than the set time.)

Setting range: 0.01 to 2.00 seconds (10ms to 2000ms)

If the set value is 0, this function becomes invalid and the interval time for sending data is set to the maximum capacity of the inverter. To obtain a quick response for sending data, set value 0.

8. Commands and monitoring from the computer

Across the network, instructions (commands and frequency) can be sent to each inverter and the operating status of each inverter can be monitored.

8.1. Communication commands (commands from the computer)

Communication command 1

(Communication Number : FA00)

Commands can be executed on inverter frequencies and operation stop through communication.

The VF-S15 series can enable command and frequency settings through communication irrespective of settings of the command mode selection (cmod) and frequency setting mode selection 1

(fmod). However, if “48 (49): Forced switching from communication to local is set by input terminal function selection (f1o4, f108, f110 to f115), a change to a command other than communication and to a frequency command is feasible through a contact on the terminal block.

Once the communication command (FA00) is set to enable communication command priority and frequency priority, both priorities will be enabled unless OFF is set, power is turned off or is reset, or factory default setting (typ) is selected. Emergency stop and PID control are always enabled even though communication command priority is not set.

Communication command 2

(Communication Number : FA20)

This command is enabled only when the communication command is enabled. Set Bit 15 of

Communication Command 1 (communication Number: FA00) to “1” (enable). When enabling the communication command by Communication Command 1, commands by communication can be given the priority irrespective of the setting of the command mode selection parameter (cm0d).

However, if “48 (49): Forced switching from communication to local is set by input terminal function selection (f1o4, f108, f110 to f115), the enabled command and frequency will be given the priority.

Once enabled, this setting will be enabled till disable is set (0 setting), power is turned off or is reset, or factory default setting (typ) is selected. Electric power quantity reset is always enabled even though communication command priority is not set.

Frequency setting from the computer

“Communication Number: FA01”

Setting range: 0 to maximum frequency (fh)

This frequency command value is enabled only when the frequency command by communication is enabled. To make frequency commands from the computer valid, set the frequency setting mode selection parameter (fmod) to RS485 communication (communication No. 0004: 3 (RS485 communication input) or select the “Command priority” option (bit 14 of FA00 : 1 (enabled)). In this case, frequency commands by communication will be enabled independent of fmod setting.

However, enabled commands and frequencies are given the priority if “48 (49): Forced switching from communication to local,” is set by input terminal function selection (f1o4, f108, f110 to f115).

Once enabled, this frequency setting will be enabled till disable is set (0 setting), power is turned off or is reset, or factory default setting (typ) is selected.

Set a frequency by communication hexadecimal in Communication Number FA01. (1=0.01Hz (unit))

(communication number: FA13)

Setting range: 0 to 24000min

The number of motor poles is selected by to f856.

The motor speed command can be set from FA13.

The output frequency is converted from the motor speed command by the following calculation formula.

If the output frequency is more than fh, Inverter return the error to the computer and the motor speed command is ignored.

Output frequency [0.01Hz] = (Output motor speed [min

-1

] x poles [f856] ) ÷ 120

This frequency command is enabled only when the frequency command by communication is enabled by setting “RS485 communication (“4” for Communication Number 0004) by the speed command selection parameter (fmod) or setting command priority (Bit 14 of Communication Number

FA00 to “1” (enable)) by the communication command. In this case, frequency command by communication will be enabled independent of fmod setting. However, enabled commands and frequencies are given the priority if “48: Forced change from communication to local,” “52: Forced operation,” or “53: Fire speed” is set by input terminal function selection (f1o4, f108, f110 to f118).

Once enabled, this frequency setting will be enabled till disable is set (0 setting), power is turned off or is reset, or standard shipment setting (typ) is selected.

FM analog output (FA51)

The FM analog output terminal on each inverter can be directly controlled with the computer.

To use this function, set the FM terminal meter selection parameter (fmsl) to 18 (RS485 communication data).

This makes it possible to send out the data specified as FM analog output (FA51) through the FM analog output terminal. Data can be adjusted in a range of 0 to 100.0 (resolution of 10 bits).

For details, refer to “Meter setting and adjustment” of the inverter’s instruction manual.

Information for reset or not (FA87)

FA87 sets to ‘1’ by user-communication. If the inverter reset, FA80 set to ‘0’ by the inverter.

8.2.Monitoring from the computer

This section explains how to monitor the operating status of the inverter from the computer.

Monitoring of the output frequency from the computer (FD00, FE00)

Output frequency (current status): “Communication Number FD00” (unit: 0.01Hz)

Output frequency (status immediately before the occurrence of a trip): “Communication Number

FE00” (unit: 0.01Hz)”

The current output frequency is read out in hexadecimal in units of 0.01Hz. For example, if the output frequency is 80Hz, 1F40H (hexadecimal number) is read out. Since the unit is 0.01Hz, 1F40H

(hexadecimal number) = 8000 (decimal number) x 0.01 = 80 (Hz)

Example: Monitoring of the output frequency (operation frequency: 50Hz) ・・・ (1F40H=8000d,

8000×0.1=80Hz)

Computer→Inverter Inverter→Computer

Monitoring of the output current with the computer (FD03, FE03)

Output current (current status): “Communication Number FD03” (unit: 0.01%)

Output current (status immediately before the occurrence of a trip): “Communication Number FE03”

(unit: 0.01%)

The current output current is read out in hexadecimal in units of 0.01%. For example, if the output current of an inverter with a current rating of 4.8A is 2.4A (50%), 1388H (hexadecimal number) is read out. Since the unit is 0.01%, 1388H (hexadecimal number) = 5000 (decimal number) x 0.01 =

50 (%)

Example: Monitoring of the output current (output current: 90%) ・ ・ ・ (2328H=9000d,

9000×0.01=90%)

Input terminal block status (FD06, FE06)

Input terminal block status (current status): “Communication Number FD06”

Input terminal block status (status immediately before the occurrence of a trip): “Communication

Number FE06”

Using terminal function selection parameters, functions can be assigned individually to the terminals on the input terminal block.

If a terminal function selection parameter is set to 0 (no function assigned), turning on or off the corresponding terminal does not affect the operation of the inverter, so that you can use the terminal as you choose.

When using a terminal as a monitoring terminal, check beforehand the function assigned to each terminal.

Terminal VIC monitor (current status): “Communication Number FE37” (unit: 0.01%)

These monitors can also be used as A/D converters irrespective of the inverter’s control.

Terminal VIA and Terminal VIC monitor are capable of reading the data from external devices in a range of 0.01 to 100.00% (unsigned data: 0H to 2710H).

Terminal VIB monitor is capable of reading the data from external devices in a range of -100.00 to

100.00% (signed data: D8F0H to 2710H).

If analog input mode is selected with the frequency setting mode selection parameter, however, keep in mind that any data entered via an analog terminal is regarded as a frequency command.

8.3.Utilizing panel (LEDs and keys) by communication

The VF-S15 can display data that is not related to the inverters through an external controller or other means. Input by key operations can also be executed. The use of inverter resources reduces the cost for the entire system.

8.3.1. LED setting by communication

Desired

LED information can be displayed by communication.

<How to Set>

Set the standard monitor display selection parameter to “communication LED setting

(f710=18).”

When in the standard monitor mode status, LED information is displayed according to the setting of

Communication Number FA65. (Set to Communication Number FA65 = 1 and initial data

“data” in shipment setting)

In case of an alarm while setting communication LEDs, the alarm display will alternately display specified LED data and alarm message.

For example, if an over-current alarm (alarm display “c”) occurs while “60.0” is displayed by this function, “c” and “60.0” will be displayed alternately.

Block Communication Function for LED Display

To display LED data for ASCII display that is synchronized to each digit, set data for each digit and validate this set data by display selection by communication (Communication Number FA65).

Synchronization can also be achieved by batch writing LED data parameters after changing the following block communication mode parameters and by sending data by block communication.

Writing in the block communication function will be writing in the RAM only due to the EEPROM life for write operations. The LED data will reset to the initial value “data“ when the power is turned off, in failure resetting or when standard shipment settings are set.

 Parameter Setting

“Block communication mode (Communication Number FA80)”

Setting range: 0, 1 (Initial value 0)

0: Block communication parameters (f870 - f879) is used

1: LED display ASCII data is used (When writing, ASCII display data 1 [Communication Number FA70 - FA74], when reading, LED data displayed before change)

*To validate LED data set by using LED display block communication, set standard monitor display selection to “communication LED select (f710 = 18) and display selection by communication to “ASCII data 1 (Communication Number FA65).

 Format

The format is the same as that used in the usual block communication mode. (For the detail infor-

mation, see “4.1.3. Transmission format of Block Communication”.) The block communication pa-

rameters (f870 - f879) will become invalid. Write data will become ASCII display data 1

(Communication Number :FA70 - FA74) fixed. LED display data that is actually being output will be read during reading. The specification range for write operations is 0 to 5.

 Example

Communication LED selection (f710 = 18) for standard monitor display selection.

ASCII data 1 (Communication Number: FA65 = 1) for display selection by communication.

LED display ASCII data (Communication Number: FA80 = 1) for the block communication mode.

Current LED display status is display of initial value “data”

8.3.2.Key utilization by communication

The VF-S15 can use the panel keys on the inverters through external communication.

 Key Monitoring Procedure

Set panel key selection (Communication Number: FA10) to “1” to set the external key mode.

However, if communication duration is less than 1sec to avoid an inverter operation shutdown in communication disruption, communication must always be maintained, such as monitoring key data and LED data to automatically reset inverter operations to inverter key operation (FA10 = 0). Set to the external communication key mode (FA10 = 1) to disable the key function of the inverters so that inverter operation will not be affected by pressing of the keys on the inverters. By monitoring key information, which is input by the keys on the inverters in this condition, through inverter key data (Communication Number; FC01), the keys on the inverters can be operated through a controller and other devices.

* When the key mode is the external key mode, key operation as an inverter function is disabled and the inverters cannot be stopped by pressing the STOP key to stop inverter operation. Enable emergency stop through an external terminal or other device when an inverter stop is desired.

Panel Key Selection (Communication Number: FA10)

The panel key selection parameter (Communication Number; FA10) discriminates which keys are to be used, panel keys on the inverters or keys sent by external communication, as panel keys used in panel processing of the inverters.

(1) “Title” means the display on the inverter panel.

(2) “Communication number” is affixed to each parameter that is necessary for designating the parameter for communication.

(3) "Adjustment range" means a data range adjustable for a parameter, and the data cannot be written outside the range. The data have been expressed in the decimal notation. For writing the data through the communication function, take the minimum setting unit into consideration, and use hexadecimal system.

(4) "Minimum setup unit" is the unit of a single data (when the minimum setting unit is "-", 1 is equal to 1).

For example, the "minimum setting unit" of acceleration time (acc) is 0.1, and 1 is equal to 0.1s. For setting a data to 10 seconds, transmit 64h [10÷0.1=100d=64h] by communication.

If 0999 is equal to 2, the acceleration/deceleration time parameters acc, dec, f500, f501, f510, f511

can be set in units of 0.1 sec. If 0999 is equal to 1, these parameters can be set in units of 0.01 sec.

2: 0.1 sec. (0.1-3600.0)

Note: Don’t write the communication number of 0999. The acceleration/deceleration time unit is set by f519.

(5) When data is a negative number, it treats as an one's complement expression (ex. FFFFH is equal to ‘-1’).

67

E6581913

 Command

For those parameters that contain data only in the RAM and not in the EEPROM, their data return to initial values when the power is turned off, in failure resetting, or when standard shipment settings are set. Note that parameters without data storage in the EEPROMs will be written in the RAM only even if the command W (writing in EEPROMs and RAM) is executed.

The state of transmission and reception can be checked in the state

An error code is returned. of communication of the status monitor function of inverter.

For details, please see inverter’s instruction manual.

- Are the same baud rate, parity and bit length set for every unit on the network?

- Is the line of network equipped with a terminator/bias resistance?

- Is the data transmission format correct?

- Does the data written fall within the specified range?

- Some parameters cannot be written during inverter operation.

Changing should be attempted when the inverter is in halt.

-f700 (Parameter protection selection) is 2: Writing prohibited

(1+RS485 communication), 4: Reading prohibited (3+RS485 com munication)

- If f738 (Password setting) was set to data, f738 can not set to data.

- Check the cable connection and the timer setting. The trip err5 and alarm t occur.

Frequency instructions from the computer have no effect.

- Is the frequency setting mode selection parameter set to “computer”?

Commands, including the run and stop commands, from the commuter have no effect.

- Is the command mode selection parameter set to “computer”?

A change to a parameter does not take effect.

Some communication-related parameters do not take effect until the inverter is reset. To make them take effect, turn the inverter off temporarily, and then turn it back on.

The setting of a parameter was changed, but it returns to its original setting when the inverter is turned off.

The setting of a parameter was changed, but the function doesn’t work.

When using the Toshiba inverter protocol, use the W command to write data into the EEPROM. If you use the P command that writes data into the RAMs only, the data will be cleared when the inverters are reset.

- Some parameters become effective after the drive is reset.

- The Modbus RTU protocol has usage restrictions.
