upper limit
A5.00 is only valid for VF control mode. In asynchronous motor VF running mode, square wave
dertermines the continuous modulation mode. Wave value＜A5.00：7-stage continuous modulation
mode. Wave value＞A5.00：5-stage continuous modulation mode.
In 7-stage continuous modulation mode, inverter switch loss is relatively big, but current ripple is
small. In 5-stage continuous modulation mode, inverter switch loss is relatively small, but current ripple
is big. High frequency may lead to motor operation instability, generally there is no need of modification.
For VF operation instability please refer to P3.11. For inverter loss and temperature rise please
refer to P0.15.

Synchronous modulation

This parameter is only valid for VF control mode. Asynchronous modulation refers to carrier
frequency that linear changes with output frequency, and ensure that the ratio of them (carrier ratio)
remains the same. Generally high output frequency is benefit for output voltage quality.
Generally, synchronous modulation is not needed at low frequencies ( below 100Hz), because the
ratio of carrier frequency and output frequency is relatively high,asynchronous modulation advantage is
more obvious.
When running frequency is greater than 85Hz, synchronous modulation is valid. And fixed as
asynchronous modulation mode when below this frequency.

Analog input AI1~AI3 of HV590L are all provided with hopping function for set value.
Hopping frequency refers to fixing of analog corresponding setup to the value of hopping point
when analog correspondending setting varies within jump point upper/lower limit.
E.g：
Voltage of analog input AI1 is in 5.00V fluctuation, which range is 4.90V~5.10V. Minimum input
0.00V corresponding to 0.0%, while maximum input 10.00V corresponding to 100.%.The corresponding
setting of AI1 fluctuates between 49.0%~51.0%.
Set A5.16 to 50.0% and A5.17 to 1.0%, after hopping function processing, AI1 is fixed as 50.0%. In
this way, AI1 is converted into a stable input, and fluctuation is eliminated.

This group of function codes are used for calibration of analog input AI , which could eliminate AI
input bias and gain influence. Generally , there is no need of calibration in application, for it has been
calibrated in factory. When restoring the factory value, the parameter would be restored to the default
value of factory calibration.
Measured voltage refers to the actual voltage that has been measured through measuring
instrument such as multimeter. Display voltage refers to the display value that has been sampled by the
inverter. See U0 group (U0.21、U0.22、U0.23) display.
During calibration, put the multimeter measurement value and the U0 value respectively into the
function codes above, inverter would automatically calibrate the AI zero off and gain.

Section VII. Inspection & Maintenance
7.1 Inspection and Maintenance
Under normal working conditions, in addition to daily inspection, the frequency converter
should be subject to regular inspection (for example inspection for overhaul or as specified but
at an interval of at most six months). Please refer to the following table in order to prevent faults.

For inspection,do not disassemble or shake the parts without reason, or pull off the plug-in-
parts at random. Otherwise, the unit will not operate normally, or can not enter the mode of fault
display, or causes faults of components or even parts of the main switch components IGBT
module is damaged.
When needing measurement, the user should note that much different results will be gained
possibly if the measuring is performed with different instruments. It is recommended that the
input voltage be measured with pointer-type voltmeter, output voltage with rectification voltmeter,
input and output current with tong-test ammeter, and power with electrically-driven wattmeter.
148
7.2 Regular replacement of the device
In order to ensure the operation reliability of the frequency converter, in addition to regular
maintenance and inspection, all the parts suffering long-term mechanical wear should be
replaced at a regular interval, which includes all cooling fans and the filtering capacitors of main
circuits for energy buffer and interchange and PCBs. For continuous use under normal
conditions, these parts can be replaced according to the following table and the operating
environment, loads and the current state of frequency converter.
Part name
Standard replacement years
Cooling fan
1~3 years
Filtering capacitor
4~5 years
PCB
5~8 years
(printed circuit board)
7.3 Storage
The following actions must be taken if the frequency converter is not put into use
immediately after delivery to the user and need to keep well for the time being or stored for a
long time：
※ Stored in a dry and adequately-ventilated place without dust and metal powder at the
temperature specified in the specifications.
※ If the frequency converter is not put into use after one year, a charge test should be made,
so as to resume the performance of the filtering capacitor of main circuit in it. For charging,
a voltage regulator should be used to slowly increase the input voltage of the frequency
converter until it reaches the rating, and the charge should last more than 1~2 hours. This
test should be made at least once a year.
※ Don’t perform breakdown test at random, for this test will cause shorter life of the frequency
converter. The insulation test must be performed after the insulation resistance is measured
with a 500-volt mega ohm and this value must not be less than 4MΩ.
7.4 Measuring and Judgment
※ If the current is measured with the general instrument, imbalance will exists for the current
at the input terminal. Generally, differing by not more than 10% is normal. If it differs by 30%,
inform the factory to replace the rectification bridge, or check if the error of three-phase
input voltage is above 5V.
※ If the three-phase output voltage is measured with a general multi-meter, the read data is
not accurate due to the interference of carrier frequency and only for reference.
7.5 Safety Precaution
※ Only specially trained persons are allowed to disassembly,replace the drive components.
※ Before the inspection and maintenance,inverter must be confirmed at least 5 minutes after
149
power off or charged(CHARGE) light is off,otherwise there is risk of electric shock.
※ Avoid metal parts leaving in the drive, or it may result in equipment damage.

I.2 Communication protocol
I.2.1 Protocol content
The serial communication protocol defines the information content and format of the
use of the transmission in serial communication. Including： the host polling (or broadcast)
format、host encoding methods.Concent including： require action of the function code,
data transmission and error checking and so on. Slave machine's response is the same
structure, including： action confirmation, return data and error checking. Slave error
occurred when receiving information, or can not do what the host request action, it will
organize a fault messageas the response back to the host computer.
Application mode：
The inverter accessing with “ single main multi-slave” PC/PLC control network which
equipped with RS232/RS485 bus.
Bus structure：
(1) Interface mode
RS232/RS485 hardware interface
(2) Transmission mode
Asynchronous serial, half-duplex transmission. At the same time host and slave
computer can only permit one to send data while the other can only receive data. Data in
the process of serial asynchronous communication is in the message format and sent one
frame by one frame.
(3) Topological mode
In single-master system, the setup range of slave address is 1 to 247. Zero refers to
broadcast communication address. The address of slave must is exclusive in the network.
That is one condition of one slave machine.
I.3 Protocol Description
HV590L series inverter communication protocol is an asynchronous serial master-slave
Modbus communication protocol, only one device in the network
(master) to establish
protocol (known as the "query / command"). Other device (slave) can only provide data
response to the host query / command, or make the appropriate action according to the
148
host query
/ command. Host refers to a personal computer
(PC), industrial control
equipment, or programmable logic controller
(PLC), etc. The slave indicates HV590L
inverter. Host can not only communicate separately with the slave, but also broadcast
messages tothe lower machine. For separate access to the host query / command, the
slave should return a message (called the response), and for broadcast information issued
by host machine , feedback needs not to be responded to the host.
Communication data structure HV590L series inverter Modbus protocol communication
data format is as follows： using RTU mode, messages are sent at least at interval of 3.5
bytes times pause. In a variety of bytes in the network baud rate of time, this could be most
easily achieved (see below T1-T2-T3-T4 shown). The transmission of a do main is the
device address.
Transmission characters are hexadecimal 0...9, A...F. Network equipment continue to
detect the network bus, including a pause interval of time. When the first field (the address
field) is received, each device decodes it to determine whether sent to their own. At least
3.5 bytes times pause after the last transmitted character, a calibration of the end of the
message. A new message may start after this pause.
The entire message frame must be used as a continuous stream. If the pause time
frame prior to the completion of more than 1.5 byte times, the receiving device will refresh
the incomplete message and assumes thatthe nextbytewill be the address field ofa
newmessage. Similarly, if a new message starts in less than 3.5 bytes times following the
previous message, the receiving device will consider it a continuationof thepreviousmessage.

I.4 Cyclical Redundancy Check
Cyclical Redundancy Check—CRC mode：CRC(Cyclical Redundancy Check) is in RTU
frame format, message contains an error-checking field that is based on a CRC method. The
CRC field checks the contents of the entire message. The CRC field is two bytes, containing a
16-bit binary value. The CRC value is calculated by the transmitting device, which appends the
CRC to the message. The receiving device recalculates a CRC during receipt of the message,
and compares the calculated value to the actual value it received in the CRC field. If the two
values are not equal, an error results. The CRC is started by 0xFFFF. Then a process begins of
applying successive 8-bit bytes of the message to the current contents of the register. Only the
eight bits of data in each character are used for generating the CRC. Start and stop bits, and the
parity bit, do not apply to the CRC.
During generation of the CRC, each eight-bit character is exclusive XOR with the register
contents. Then the result is shifted in the direction of the least significant bit (LSB), with a ZERO
filled into the most significant bit (MSB) position. The LSB extracted and examined. If the LSB
was 1, the register then exclusive XOR with a preset, fixed value. If the LSB was 0, no exclusive
XOR takes place. This process is repeated until 8 shifts have been performed. After the last (8)
shift, the next eight-bit byte is exclusive XOR with the register’s current value, and the process
repeats for 8 more shifts as described above. The final contents of the register, after all the
bytes of the message have been applied, is the CRC value.
When CRC appended to the message, the low byte is appended first, and then the high
byte.
CRC calculation program：
unsigned int cal_crc16
(unsigned char *data, unsigned int length)
{
unsigned int i,crc_result=0xffff;
while(length--)
{
crc_result^=*data++;
for(i=0;i<8;i++)
{
if(crc_result&0x01)
151
crc_result=(crc_result>>1)^0xa001;
else
crc_result=crc_result>>1;
}
}
crc_result=((crc_result&0xff)<<8)|(crc_result>>8);
return(crc_result);

I.5 Communication parameter address
The chapter is about communication contents, it’s used to control the inverter operation, the
status of the inverter and related parameter setup. Read and write functioncode parameters
(Some function codesare not able to be changed, only for the manufacturer use.). The mark
rules of function code parameters address：
The group number and mark of function codesare parameter address for indication rules.
High byte：F0~FF(P group), A0~AF(A group), 70~F(U group)Low byte：00~FF
For example： P3.12, the address indicates F30C
Caution：
Group PF： Parameters could not be read or be modified.
Group U： Parameters could be read but not be modified.
Some parameters can not be changed during operation, some parameters regardless of
the kind of state the inverter in, the parameters can not be changed. Change the function code
parameters, pay attention to the scope of the parameters, units, and relative instructions.
Besides, if EEPROM is frequently stored, it will reduce the service life of EEPROM. In some
communication mode, function code needto be stored as long as changing the RAM value.
Group P： to achieve this function, change high order F of the function code address into 0.
Group A： to achieve this function, change high order A of the function code address to be 4.
Corresponding function code address are indicated below：
High byte： 00~0F(P group), 40~4F(A group)Low byte： 00~FF
For example：
Function code P3.12 can not be stored into EEPROM, address indicates to be
030C,function code A0-05 can not be stored in EEPROM, address indicates to be 4005；This
address can only act writing RAM, it can not act reading, when act reading, it is invalid address.
For all parameters, command code 07H can be used to achieve this function.
