Protect the VFD and input power cable during short-circuit to aviod thermal overload.

Carry out protective measures according to the following requirements.

VFD

Input cable

Fuse

Figure 3-7 Fuse configuration

Note: Select the fuse according to operation manual. During short-circuit, the fuse will
protect input power cables to avoid damage to the VFD; when internal short-circuit occurred
to the VFD, it can protect neighboring equipment from being damaged.

-17-
 Installation guidelines

3.3.2 Protect the motor and motor cables

If the motor cable is selected based on the rated current of the VFD, the VFD can protect
the motor cable and motor when a short circuit occurs. The VFD provides the motor thermal
overload protection function, which can protect the motor, and lock the output and cut off the
current when necessary.

 If the VFD is connected to multiple motors, it is a must to use a

separated thermal overload switch or breaker to protect the cable and
motor, which may require the fuse to cut off the short circuit current.

3.3.3 Establish a bypass connection

In some critical occasions, industrial frequency conversion circuit is necessary to ensure

proper operation of the system when a VFD fault occurs. In some special cases, such as,
only soft startup is needed, it will convert to power-frequency operation directly after soft
startup, corresponding bypass link is also needed.

 Do not connect any power source to VFD output terminals U, V and W.

The voltage applied to motor cable may cause permanent damage to
the VFD.

If frequent switch-over is needed, you can use the switch which carries mechanical interlock
or a contactor to ensure motor terminals will not be connected to input power cables and
VFD output ends simultaneously.

4.2 Keypad display
The keypad of Goodrive10 series VFD displays the stopped-state parameters, running-state
parameters, function parameter editing status, and fault alarm status.
4.2.1 Displaying stopped-state parameters
When the VFD is in stopped state, the keypad displays stopped-state parameters.

In the stopped state, parameters in various states can be displayed. You can determine
which parameters are displayed by setting the binary bits of P07.07. For definitions of the
bits, see the description of P07.07.

In stopping state, there are 10 parameters that can be selected for display, including set
frequency, bus voltage, input terminal state, output terminal state, PID reference, PID
feedback, AI1, AI2, current step of multi-step speed, and pulse counting. P07.07 can select
the parameter to be displayed or not by bit, and you can press 》/SHIFT to shift selected
parameters from left to right or press QUICK/JOG to shift selected parameters from right to
left.

4.2.2 Displaying running-state parameters

After receiving a valid running command, the VFD enters the running state, and the keypad
displays running-state parameters, with the RUN/TUNE indicator on. The on/off state of the
FWD/REV indicator is determined by the current running direction.

In running state, there are 20 parameters that can be selected for display, including running
frequency, set frequency, bus voltage, output voltage, output current, running speed, output
power, output torque, PID reference PID feedback, input terminal state, output terminal state,
pulse counting, current step of multi-step speed, AI1, AI2, motor overload percentage, VFD
overload percentage, ramp frequency reference, and linear speed. P07.05 and P07.06 can
select the parameter to be displayed or not by bit, and you can press 》/SHIFT to shift
selected parameters from left to right or press QUICK/JOG to shift selected parameters
from right to left.

4.2.3 Displaying fault information

After detecting a fault signal, the VFD enters the fault alarm state immediately, the fault code
blinks on the keypad, and the TRIP indicator is on. You can perform fault reset by using the
STOP/RST key, control terminals, or communication commands.
If the fault persists, the fault code is continuously displayed.

4.2.4 Editing function codes

You can press the PRG/ESC key to enter the editing mode in stopped, running, or fault
alarm state (if a user password is used, see the description of P07.00). The editing mode
contains two levels of menus in the following sequence: Function code group or function
code number → Function code setting. You can press the DATA/ENT key to enter the
function parameter display interface. On the function parameter display interface, you can
press the DATA/ENT key to save parameter settings or press the PRG/ESC key to exit the
parameter display interface.

4.3 Operations on the keypad

You can operate the VFD by using the keypad. For details about function code descriptions,
see the function code list.

4.3.1 Modifying VFD function codes

The VFD provides three levels of menus, including:

1. Function code group number (level-1 menu)

2. Function code number (level-2 menu)

3. Function code setting (level-3 menu)

Note: When performing operations on the level-3 menu, you can press the PRG/ESC or
DATA/ENT key to return to the level-2 menu. If you press the DATA/ENT key, the set value
of the parameter is saved to the control board first, and then the level-2 menu is returned,
displaying the next function code. If you press the PRG/ESC key, the level-2 menu is
returned directly, without saving the set value of the parameter, and the current function
code is displayed.

If you enter the level-3 menu but the parameter does not have a digit blinking, the parameter

cannot be modified due to either of the following reasons:

1) It is read only. Read-only parameters include actual detection parameters and running
record parameters.

2) It cannot be modified in running state and can be modified only in stopped state.

 Function parameters

5 Function parameters
The function parameters of Goodrive10 series VFDs have been divided into 30 groups
(P00–P29) according to the function, of which P18–P28 are reserved. Each function group
contains certain function codes. A three-level menu style is applied to function codes. For
example, "P08.08" indicates the 8th function code in the P8 group. The P29 group consist of
factory function parameters, which are user inaccessible.

The function group numbers correspond to the level-1 menus, the function codes
correspond to the level-2 menus, and the function parameters correspond to the level-3
menus.

1. The content of the function code table is as follows:

Column 1 "Function code": Code of the function group and parameter.

Column 2 "Name": Full name of the function parameter.

Column 3 "Description": Detailed description of the function parameter.

Column 4 "Default": Initial value set in factory.

Column 5 "Modify": Whether the function parameter can be modified, and conditions for the
modification.

"○" indicates that the value of the parameter can be modified when the VFD is in the stop or
running state.

"◎" indicates that the value of the parameter cannot be modified when the VFD is in the
running state.

"●" indicates that the value of the parameter is detected and recorded, and cannot be
modified.

Note: The VFD automatically checks and constrains the modification of parameters, which
helps prevent incorrect modifications.

The cooling is better. The current of the stator

6.1.2 Cooling fan
The service life of the cooling fan of the VFD is more than 25,000 hours. The actual service
life of the cooling fan is related to the use of the VFD and the temperature in the ambient
environment. You can view the running duration of the VFD through P07.14 (Accumulated
running time).

The increase of the bearing noise indicates a fan fault. If the VFD is applied in a key position,
replace the fan once the fan starts to generate unusual noise. You can purchase spare
parts of fans from HL.

 Read and follow the instructions in chapter 1 "Safety precautions".

Ignoring the instructions would cause physical injury or death, or
damage to the equipment.

1. Stop the VFD and disconnect it from the AC power source and wait for at least the time
designated on the VFD.

2. Lever the fan mounting plate from the cabinet with a screwdriver, and lift the fan
mounting plate slightly upward.

3. Disconnect the fan cable.

4. Remove the fan cable, and remove the fan mounting plate.

5. Install the new fan mounting plate including the fan back to the VFD in reverse order.

6. Power on the VFD.

6.1.3 Capacitors
Capacitor reforming

If the VFD has been left unused for a long time, you need to follow the instructions to reform
the DC bus capacitor before using it. The storage time is calculated from the date the VFD is
delivered.

Storage time Operation principle

Less than 1 year No charging operation is required.
The VFD needs to be powered on for 1 hour before the first

running command.
-79-
 Fault tracking

Storage time Operation principle

Use a voltage controlled power supply to charge the VFD:
Charge the VFD at 25% of the rated voltage for 30 minutes,
2 to 3 years and then charge it at 50% of the rated voltage for 30 minutes,
at 75% for another 30 minutes, and finally charge it at 100%
of the rated voltage for 30 minutes.
Use a voltage controlled power supply to charge the VFD:
Charge the VFD at 25% of the rated voltage for 2 hours, and
More than 3 years then charge it at 50% of the rated voltage for 2 hours, at 75%
for another 2 hours, and finally charge it at 100% of the rated
voltage for 2 hours.

The method for using a voltage controlled power supply to charge the VFD is described as
follows:

The selection of a voltage controlled power supply depends on the power supply of the VFD.
For VFDs with an incoming voltage of 1PH/3PH 220 V AC, you can use a 220 V AC/2 A
voltage regulator. Both 1PH and 3PH VFDs can be charged with a 1PH voltage controlled
power supply (connect L+ to R, and N to S or T). All the DC bus capacitors share one
rectifier, and therefore they are all charged.

For VFDs of a high voltage class, ensure that the voltage requirement (for example, 380 V)
is met during charging. Capacitor changing requires little current, and therefore you can use
a small-capacity power supply (2 A is sufficient).

Change electrolytic capacitors

 Read and follow the instructions in chapter 1 "Safety precautions".

Ignoring the instructions may cause physical injury or death, or damage
to the equipment.

The electrolytic capacitor of a VFD must be replaced if it has been used for more than
35,000 hours. For details about the replacement, contact with the local HL offices or diall
our national service hotline (400-700-9997) for detailed operation.

6.1.4 Power cable

 Read and follow the instructions in chapter 1 "Safety precautions".

Ignoring the instructions may cause physical injury or death, or damage
to the equipment.

1. Stop the VFD, disconnect the power supply, and wait for a time no shorter than the
waiting time designated on the VFD.

-80-
 Fault tracking

2. Check the connection of the power cables. Ensure that they are firmly connected.

3. Power on the VFD.

6.2 Fault handling

 Only qualified electricians are allowed to maintain the VFD. Read the
safety instructions in chapter 1 "Safety precautions" before working on
the VFD.

6.2.1 Alarm and fault indications

Fault is indicated by LEDs. See chapter 4 “Keypad”. When TRIP light is on, an alarm or fault
message on the panel display indicates abnormal VFD state. P07.27–P07.32 record the
lastest 6 fault type and P07.33–P07.56 record the operation data of the lastest 3 fault type.
Using the information reference in this chapter, most alarm and fault cause can be
identified and corrected. If not, contact with the HL office.
6.2.2 Fault reset
The VFD can be reset by pressing the keypad key STOP/RST, through digital input, or by
switching the power light. When the fault has been removed, the motor can be restarted.
6.2.3 Fault instruction and solution
Do as the following after the VFD fault:

1. Check to ensure there is nothing wrong with the keypad. If not, please contact with the
local HL office.

2. If there is nothing wrong, please check P07 and ensure the corresponding recorded fault
parameters to confirm the real state when the current fault occurs by all parameters.

3. See the following table for detailed solution and check the corresponding abnormal state.

4. Eliminate the fault and ask for relative help.

5. Check to eliminate the fault and carry out fault reset to run the VFD.

Note: The numbers enclosed in square brackets such as [4], [5] and [6] in the Fault type

 Communication protocol

7 Communication protocol
7.1 Modbus protocol introduction
Modbus protocol is a software protocol and common language which is applied in the
electrical controller. With this protocol, the controller can communicate with other devices
via network (the channel of signal transmission or the physical layer, such as RS485). And
with this industrial standard, the controlling devices of different manufacturers can be
connected to an industrial network for the convenient of being monitored.

There are two transmission modes for Modbus protocol: ASCII mode and RTU (Remote
Terminal Units) mode. On one Modbus network, all devices should select same
transmission mode and their basic parameters, such as baud rate, digital bit, check bit, and
stopping bit should have no difference.

Modbus network is a controlling network with single-master and multiple slaves, which
means that there is only one device performs as the master and the others are the slaves on
one Modbus network. The master means the device which has active talking right to sent
message to Modbus network for the controlling and inquiring to other devices. The slave
means the passive device which sends data message to the Modbus network only after
receiving the controlling or inquiring message (command) form the master (response). After
the master sends message, there is a period of time left for the controlled or inquired slaves
to response, which ensure there is only one slave sends message to the master at a time for
the avoidance of singles impact.

Generally, the user can set PC, PLC, IPC and HMI as the masters to realize central control.
Setting certain device as the master is a promise other than setting by a bottom or a switch
or the device has a special message format. For example, when the upper monitor is
running, if the operator clicks sending command bottom, the upper monitor can send
command message actively even it can not receive the message form other devices. In this
case, the upper monitor is the master. And if the designer makes the VFD send the data
only after receiving the command, then the VFD is the slave.

The master can communicate with any single slave or with all slaves. For the single-visiting
command, the slave should feedback a response message; for the broadcasting message
from the master, the slave does not need to feedback the response message.

7.2 Application mode for the VFD

The VFD uses the Modbus RTU mode and the physical layer is 2-wire RS485.
7.2.1 2-wire RS485
2-wire RS485 interfaces works in half-duplex mode and send data signals in the differential
transmission way, which is also referred to as balanced transmission. An RS485 interface
-84-
 Communication protocol

uses a twisted pair, in which one wire is defined as A (+), and the other B (-). Generally, if the
positive electrical level between the transmission drives A and B ranges from +2 V to +6 V,
the logic is "1"; and if it ranges from -2 V to -6 V, the logic is "0".

On the VFD terminal block, the 485+ terminal corresponds to A, and 485- corresponds to B.

The communication baud rate (P14.01) indicates the number of bits sent in a second, and
the unit is bit/s (bps). A higher baud rate indicates faster transmission and poorer
anti-interference capability. When a twisted pair of 0.56mm (24 AWG) is used, the maximum
transmission distance varies according to the baud rate, as described in the following table.

Max. Max. Max. Max.

Baud Baud Baud Baud

rate rate rate rate
distance distance distance distance
2400 4800 9600 19200
1800m 1200m 800m 600m
BPS BPS BPS BPS

When RS485 interfaces are used for long-distance communication, it is recommended that
you use shielded cables, and use the shielding layer as the ground wires.

When there are fewer devices and the transmission distance is short, the whole network
works well without terminal load resistors. The performance, however, degrades as the
distance increases. Therefore, it is recommended that you use a 120Ω terminal resistor
when the transmission distance is long.I

7.2.1.1 When one VFD is used

Figure 7-1 is the Modbus wiring diagram for the network with one VFD and PC. Generally,
PCs do not provide RS485 interfaces, and therefore you need to convert an RS232 or USB
interface of a PC to an RS485 interface through a converter. Then, connect end A of the
RS485 interface to the 485+ port on the terminal block of the VFD, and connect end B to the
485- port. It is recommended that you use shielded twisted pairs. When an RS232-RS485
converter is used, the cable used to connect the RS232 interface of the PC and the
converter cannot be longer than 15 m. Use a short cable when possible. It is recommended
that you insert the converter directly into the PC. Similarly, when a USB-RS485 converter is
used, use a short cable when possible.

When the wiring is completed, select the correct port (for example, COM1 to connect to the
RS232-RS485 converter) for the upper computer of the PC, and keep the settings of basic
parameters such as communication baud rate and data check bit consistent with those of
the VFD.Select

7.2.1.2 When multiple VFDs are used

In the network with multiple VFDs, chrysanthemum connection and star connection are
commonly used. According to the requirements of the RS485 industrial bus standards, all
the devices need to be connected in chrysanthemum mode with one 120 Ω terminal resistor
on each end, as shown in Figure 7-2.

 Communication protocol

Use shielded cables, if possible, in multi-VFD connection. The baud rates, data bit check
settings, and other basic parameters of all the devices on the RS485 line must be set
consistently, and addresses cannot be repeated.

7.2.2 RTU mode

7.2.2.1 RTU communication frame format
If the controller is set to communicate by RTU mode in Modbus network every 8bit byte in
the message includes two 4Bit hex characters. Compared with ACSII mode, this mode can
send more data at the same baud rate.

Code system

• 1 start bit

• 7 or 8 digital bit, the minimum valid bit can be sent firstly. Every 8 bit frame includes two
hex characters (0...9, A...F)

• 1even/odd check bit . If there is no checkout, the even/odd check bit is inexistent.

• 1 stop bit (with checkout), or 2 bits (no checkout)

Error detection domain

• Cyclic redundancy check (CRC)

The following table describes the data format.

11-bit character frame (Bits 1 to 8 are data bits)

Check EStop
Start bit BIT1 BIT2 BIT3 BIT4 BIT5 BIT6 BIT7 BIT8
bit bit

10-bit character frame (Bits 1 to 7 are data bits)

Check EStop
Start bit BIT1 BIT2 BIT3 BIT4 BIT5 BIT6 BIT7
bit bit

In a character frame, only the data bits carry information. The start bit, check bit, and stop bit
are used to facilitate the transmission of the data bits to the destination device. In practical
applications, you must set the data bits, parity check bits, and stop bits consistently.

In RTU mode, the transmission of a new frame always starts from an idle time (the
transmission time of 3.5 bytes). On a network where the transmission rate is calculated
based on the baud rate, the transmission time of 3.5 bytes can be easily obtained. After the
idle time ends, the data domains are transmitted in the following sequence: slave address,
operation command code, data, and CRC check character. Each byte transmitted in each
domain includes 2 hexadecimal characters (0–9, A–F). The network devices always monitor

-87-
 Communication protocol

the communication bus. After receiving the first domain (address information), each network
device identifies the byte. After the last byte is transmitted, a similar transmission interval
(the transmission time of 3.5 bytes) is used to indicate that the transmission of the frame
ends. Then, the transmission of a new frame starts.

RTU data frame format

Modbus packet
Start, preceded by End, followed by a
a time gap with a Slave Function time gap with a

3.5 characters 3.5 characters

The information of a frame must be transmitted in a continuous data flow. If there is an

interval greater than the transmission time of 1.5 bytes before the transmission of the entire
frame is complete, the receiving device deletes the incomplete information, and mistakes
the subsequent byte for the address domain of a new frame. Similarly, if the transmission
interval between two frames is shorter than the transmission time of 3.5 bytes, the receiving
device mistakes it for the data of the last frame. The CRC check value is incorrect due to the
disorder of the frames, and thus a communication fault occurs.

The following table describes the standard structure of an RTU frame.

END (frame tail) T1-T2-T3-T4 (time gap with a min. length of 3.5 bytes)
7.2.2.2 RTU communication frame error check modes
During the transmission of data, errors may occur due to various factors (such as
electromagnetic interference). For example, if the sending message is a logic "1", A-B
potential difference on RS485 should be 6V, but in reality, it may be -6V because of
electromagnetic interference, and then the other devices take the sent message as logic "0".
Without error check, the data receiving device cannot identify data errors and may make a
wrong response. The wrong response may cause severe problems. Therefore, the data
must be checked.

-88-
 Communication protocol

The check is implemented as follows: The transmitter calculates the to-be-transmitted data
based on a specific algorithm to obtain a result, adds the result to the rear of the message,
and transmits them together. After receiving the message, the receiver calculates the data
based on the same algorithm to obtain a result, and compares the result with that
transmitted by the transmitter. If the results are the same, the message is correct. Otherwise,
the message is considered wrong.

The error check of a frame includes two parts, namely, bit check on individual bytes (that is,
odd/even check using the check bit in the character frame), and whole data check (CRC
check).

Bit check on individual bytes (odd/even check)

You can select the bit check mode as required, or you can choose not to perform the check,
which will affect the check bit setting of each byte.

Definition of even check: Before the data is transmitted, an even check bit is added to indicate
whether the number of "1" in the to-be-transmitted data is odd or even. If it is even, the check
bit is set to "0"; and if it is odd, the check bit is set to "1".

Definition of odd check: Before the data is transmitted, an odd check bit is added to indicate
whether the number of "1" in the to-be-transmitted data is odd or even. If it is odd, the check bit
is set to "0"; and if it is even, the check bit is set to "1".

For example, the data bits to be transmitted are "11001110", including five "1". If the even
check is applied, the even check bit is set to "1"; and if the odd check is applied, the odd check
bit is set to "0". During the transmission of the data, the odd/even check bit is calculated and
placed in the check bit of the frame. The receiving device performs the odd/even check after
receiving the data. If it finds that the odd/even parity of the data is inconsistent with the preset
information, it determines that a communication error occurs.

Cyclical Redundancy Check (CRC) method

A frame in the RTU format includes an error detection domain based on the CRC calculation.
The CRC domain checks all the content of the frame. The CRC domain consists of two bytes,
including 16 binary bits. It is calculated by the transmitter and added to the frame. The receiver
calculates the CRC of the received frame, and compares the result with the value in the
received CRC domain. If the two CRC values are not equal to each other, errors occur in the
transmission.

During CRC, 0xFFFF is stored first, and then a process is invoked to process a minimum of 6
contiguous bytes in the frame based on the content in the current register. CRC is valid only
for the 8-bit data in each character. It is invalid for the start, stop, and check bits.

During the generation of the CRC values, the "exclusive or" (XOR) operation is performed on

-89-
 Communication protocol

the each 8-bit character and the content in the register. The result is placed in the bits from the
low-order bit to the high-order bit, and 0 is placed in the high-order bit. Then, the low-order bit
is detected. If the low-order bit is 1, the XOR operation is performed on the current value in the
register and the preset value. If low-order bit is 0, no operation is performed. This process is
repeated 8 times. After the last bit (8th bit) is detected and processed, the XOR operation is
performed on the next 8-bit byte and the current content in the register. The final values in the
register are the CRC values obtained after operations are performed on all the bytes in the
frame.

The calculation adopts the international standard CRC check rule. You can refer to the related
standard CRC algorithm to compile the CRC calculation program as required.

Here provided a simple function of CRC calculation for the reference (programmed with C
language):

unsigned int crc_cal_value(unsigned char *data_value,unsigned char

data_length)
{
int i;
unsigned int crc_value=0xffff;
while(data_length--)
{ crc_value^=*data_value++;
for(i=0;i<8;i++)
{
if(crc_value&0x0001)crc_value=(crc_value>>1)^0xa001;
else crc_value=crc_value>>1;
} }
return(crc_value);
}
In the ladder logic, CKSM uses the table look-up method to calculate the CRC value
according to the content in the frame. The program of this method is simple, and the
calculation is fast, but the ROM space occupied is large. Use this program with caution in
scenarios where there are space occupation requirements on programs.
7.3 RTU command code and communication data description
7.3.1 Command code: 03H
03H (corresponding to binary 0000 0011), read N words (Word) (N≤16)

Command code 03H means that if the master read data form the VFD, the reading number
depends on the “data number” in the command code. The Max. Continuous reading number
is 16 and the parameter address should be continuous. The byte length of every data is 2
(one word). The following command format is illustrated by hex (a number with “H” means

-90-
 Communication protocol

hex) and one hex occupies one byte.

The command code is used to read the working stage of the VFD.

For example, read continuous 2 data content from0004H from the VFD with the address of
01H (read the content of data address of 0004H and 0005H), the frame structure is as
follows:

RTU master command (sent from the RTU slave response (sent from the VFD to
master to the VFD) the master)
START T1-T2-T3-T4 START T1-T2-T3-T4
ADDR 01H ADDR 01H
CMD 03H CMD 03H
Byte number 04H
MSB of the start
00H MSB of data in 0004H 13H
address
LSB of the start
04H LSB of data in 0004H 88H
address
MSB of data number 00H MSB of data in 0005H 00H
LSB of data number 02H LSB of data in 0005H 00H
LSB of CRC 85H LSB of CRC CHK 7EH
MSB of CRC CAH LSB of CRC CHK 9DH
END T1-T2-T3-T4 END T1-T2-T3-T4

T1-T2-T3-T4 between START and END is to provide at least the time of 3.5 bytes as the
leisure time and distinguish two messages for the avoidance of taking two messages as one
message.

ADDR = 01H means the command message is sent to the VFD with the address of 01H and
ADDR occupies one byte.

CMD=03H means the command message is sent to read data from the VFD and CMD
occupies one byte.

"Start address" means reading data from the address and it occupies 2 bytes with the fact
that the MSB is in the front and the LSB is in the behind.

"Data number" means the reading data number with the unit of word. If the "start address" is
0004H and the "data number" is 0002H, the data of 0004H and 0005H will be read.

CRC occupies 2 bytes with the fact that the LSB is in the front and the MSB is in the behind.

The meaning of the response is that:

-91-
 Communication protocol

ADDR = 01H means the command message is transmitted by the VFD whose address is
01H. The ADDR information occupies one byte.

CMD=03H means the message is received from the VFD to the master for the response of
reading command The CMD information occupies one byte.

"Byte number" means all byte number from the byte (excluding the byte) to CRC byte
(excluding the byte). 04 means there are 4 byte of data from the "byte number" to "LSB of
CRC CHK", which are "MSB of data in 0004H", "LSB of data in 0004H", "MSB of data in
0005H" and "LSB of data in 0005H".

There are 2 bytes stored in one data with the fact that the MSB is in the front and the LSB is
in the behind of the message, the data of data address 0004H is 1388H, and the data of
data address 0005H is 0000H.

CRC occupies 2 bytes with the fact that the LSB is in the front and the MSB is in the behind.

7.3.2 Command code: 06H

06H (corresponding to binary 0000 0110), write a word

The command means that the master write data to the VFD and one command can write
one data other than multiple dates. The effect is to change the working mode of the VFD.

For example, write 5000 (1388H) to 0004H from the VFD with the address of 02H, the frame
structure is as follows.

RTU master command (sent from the RTU slave response (sent from the VFD to
master to the VFD) the master)

7.3.4 Data address definition
This section describes the address definition of communication data. The addresses are
used for controlling the running, obtaining the status information, and setting function
parameters of the VFD.
7.3.4.1 Function code address format rules
The parameter address occupies 2 bytes with the fact that the MSB is in the front and the
LSB is in the behind. The range of MSB and LSB are: MSB—00–ffH; LSB—00–ffH. The
MSB is the group number before the radix point of the function code and the LSB is the
number after the radix point. But both the MSB and the LSB should be changed into hex.
For example P05.05, the group number before the radix point of the function code is 05,
then the MSB of the parameter is 05, the number after the radix point 05, then the LSB of
the parameter is 05, then the function code address is 0505H and the parameter address of
P10.01 is 0A01H.
Note:
 P29 group is the factory parameter which cannot be read or changed. Some
parameters cannot be changed when the VFD is in the running state and some
parameters cannot be changed in any state. The setting range, unit and related
-93-
 Communication protocol

instructions should be paid attention to when modifying the function code parameters.
 EEPROM is stocked frequently, which may shorten the usage time of EEPROM. For
users, some functions are not necessary to be stocked on the communication mode.
The needs can be met on by changing the value in RAM. Changing the MSB of the
function code form 0 to 1 can also realize the function. For example, the function code
P00.07 is not stocked into EEPROM. Only by changing the value in RAM can set the
address to 8007H. This address can only be used in writing RAM other than reading. If
it is used to read, it is an invalid address.
7.3.4.2 Description of other function addresses in Modbus
BIn addition to modifying the parameters of the VFD, the master can also control the VFD,
such as start and stop it, and monitor the operation state of the VFD. The following table
describes other function parameters.

The Read/Write (R/W) characteristics indicate whether a function can be read and written.
For example, "Communication-based control command" can be written, and therefore the
command code 6H is used to control the VFD. The R characteristic indicates that a function
can only be read, and W indicates that a function can only be written.
Note: Some parameters in the preceding table are valid only after they are enabled. Take
the running and stop operations as examples, you need to set "Running command channel"
(P00.01) to "Communication", and set "Communication running command channel" (P00.02)
to the Modbus communication channel. For another example, when modifying "PID setting",
you need to set "PID reference source" (P09.00) to Modbus communication.
The following table describes the encoding rules of device codes (corresponding to the
identification code 2103H of the VFD).

Note: The code is consisted of 16 bit which is 8 MSBs and 8 LSBs. 8 MSBs indicate the
motor type series and 8 LSBs indicate the derived motor types of the series.

7.3.5 Fieldbus ratio scale

In practical applications, communication data is represented in the hexadecimal form, but

hexadecimal values cannot represent decimals. For example, 50.12Hz cannot be
represented in the hexadecimal form. In such cases, we can multiply 50.12 by 100 to obtain
an integer 5012, and then 50.12 can be represented as 1394H (5012 in the decimal form) in
the hexadecimal form.

In the process of multiplying a non-integer by a multiple to obtain an integer, the multiple is

referred to as a fieldbus scale.

The fieldbus scale depends on the number of decimals in the value specified in
"Description" or "Default ". If there are n decimals in the value, the fieldbus scale m is the
nth-power of 10. Take the following table as an example, m is 10.

Function
Name Description Default Modify
code
Wake-up–from-sleep 0.0–3600.0s (valid when
P01.20 0.0s ○
delay P01.19=2)
0: Disable
P01.21 Restart after power off 0 ○
1: Enable

The value specified in "Setting range" or "Default" contains one decimal, so the fieldbus
scale is 10. If the value received by the upper computer is 50, the value of
"Wake-up-from-sleep delay" of the VFD is 5.0 (5.0=50/10).

To set the "Wake-up-from-sleep delay" to 5.0s through Modbus communication, you need
first to multiply 5.0 by 10 according to the scale to obtain an integer 50, that is, 32H in the
hexadecimal form, and then transmit the following write command:

VFD Write Parameters Data number CRC check

address command address

After receiving the command, the VFD converts 50 into 5.0 based on the fieldbus scale, and
then sets "Wake-up-from-sleep delay" to 5.0s.

For another example, after the upper computer transmits the "Wake-up-from-sleep
delay"parameter command, the master receives the following response from the VFD:

01 03 02 00 32 39 91
VFD Read 2-byte Parameter CRC check
address command data data

-97-
 Communication protocol

The parameter data is 0032H, that is, 50, so 5.0 is obtained based on the fieldbus scale
(50/10=5.0). In this case, the master identifies that the "Wake-up-from-sleep delay" is 5.0s.

7.3.6 Error message response

Operation errors may occur in communication-based control. For example, some

parameters can only be read, but a write command is transmitted. In this case, the VFD
returns an error message response. Error message responses are sent from the VFD to the
master. The following table describes the codes and definitions of the error message
responses.

allowed to be executed. The possible causes are as
follows:

The slave uses functional code fields and fault addresses to indicate it is a normal response
or some error occurs (named as objection response). For normal responses, the slave
shows corresponding function codes, digital address or sub-function codes as the response.
For objection responses, the slave returns a code which equals the normal code, but the
first byte is logic 1.

For example: when the master sends a message to the slave, requiring it to read a group of
address data of the VFD function codes, there will be following function codes:

0 0 0 0 0 0 1 1 (Hex 03H)

For normal responses, the slave responds the same codes, while for objection responses, it
will return:

1 0 0 0 0 0 1 1 (Hex 83H)

Besides the function codes modification for the objection fault, the slave will respond a byte
of abnormal code which defines the error reason. When the master receives the response
for the objection, in a typical processing, it will send the message again or modify the
corresponding order.

For example, set the “running command channel” of the VFD (P00.01, parameter address is
0001H) with the address of 01H to 03, the command is as following:

01 06 00 01 00 03 98 0B
VFD Write Parameter Parameter CRC check
address command address data

But the setting range of “running command channel” is 0–2, if it is set to 3, because the
number is beyond the range, the VFD will return fault response message as below:

01 86 04 43 A3
VFD Exception Fault code CRC check
address response code

-99-
 Communication protocol

Abnormal response code 86H means the abnormal response to writing command 06H; the
fault code is 04H. In the table above, its name is operation failed and its meaning is that the
parameter setting in parameter writing is invalid.

7.3.7 Read/Write operation example

For details about the formats of the read and write commands, see section 7.3.

7.3.7.1 Examples of reading command 03H

Read the state word 1 of the VFD with the address of 01H (see section 7.3.4.2 “Description
of other function addresses in Modbus”). The parameter address of the state word 1 of the
VFD is 2100H.

The command sent to the VFD:

01 03 21 00 00 01 8E 36
VFD Read Parameter Data quantity CRC check
address command address

If the response message is as below:

01 03 02 00 03 F8 45
VFD Read Number Data content CRC check
address command of bytes

The data content is 0003H. From the table 1, the VFD stops.

Watch “the current fault type” to “the previous 5 times fault type” of the VFD through
commands, the corresponding function code is P07.27–P07.32 and corresponding
parameter address is 071BH–0720H(there are 6 from 071BH).

The command sent to the VFD:

03 03 07 1B 00 06 B5 59
VFD Read Start 6 parameters in total CRC check
address command address

If the response message is as below:

03 03 0C 00 23 00 23 00 23 00 23 00 23 00 23 5F D2
VFD Read Number of Type of Type of Type of last Type of last Type of last Type of last CRC check
address command bytes current fault last fault but one fault but two fault but three fault but four fault

See from the returned data, all fault types are 0023H (decimal 35) with the meaning of
maladjustment (STo).

7.4 Common communication faults

Common communication faults include the following:

 No response is returned.

 The VFD returns an exception response.

Possible causes of no response include the following:

 The serial port is set incorrectly. For example, the converter uses the serial port COM1,
but COM2 is selected for the communication.

 The settings of the baud rates, data bits, stop bits, and check bits are inconsistent with
those set on the VFD.

 The positive pole (+) and negative pole (-) of the RS485 bus are connected reversely.

 The RS485 wire cap on the terminal board of the VFD is not connected. This wire cap is
at the back of the terminal block.
