maintenance DANGER before starting repair or maintenance on the AC drive.
• Set and check the parameters again after the AC drive is
replaced.
• All the pluggable components must be plugged or removed only
after power- off.
• The rotating motor generally feeds back power to the AC
drive. As a result, the AC drive is still charged even if the
motor stops, and the power supply is cut off. Thus
ensure that the AC drive is disconnected from the motor before
starting repair or maintenance on the AC drive.

1.2 General Precautions

1) Requirement on residual current device (RCD)
The AC drive generates high leakage current during running, which flows through the
protective earthing ( PE) conductor. Thus install a type- B RCD at primary side of the
power supply. When selecting the RCD, you should consider the transient and steady-
state leakage current to ground that may be generated at startup and during running of
the AC drive. You can select a specialized RCD with the function of suppressing high
harmonics or a general-purpose RCD with relatively large residual current.
2) High leakage current warning
The AC drive generates high leakage current during running, which flows through the
PE conductor. Earth connection must be done before connection of power supply.
Earthing shall comply with local regulations and related IEC standards.

4
3) Motor insulation test
Perform the insulation test when the motor is used for the first time, or when it is reused
after being stored for a long time, or in a regular check-up, in order to prevent the poor
insulation of motor windings from damaging the AC drive. The motor must be
disconnected from the AC drive during the insulation test. A 500-V mega-Ohm meter is
recommended for the test. The insulation resistance must not be less than 5 MΩ .

4) Thermal protection of motor

If the rated capacity of the motor selected does not match that of the AC drive,
especially when the AC drive's rated power is greater than the motor's, adjust the motor
protection parameters on the operation panel of the AC drive or install a thermal relay
in the motor circuit for protection.
5) Running at over 50 Hz
The AC drive provides frequency output of 0 to 3200 Hz (Up to 300 Hz is supported if
the AC drive runs in CLVC and SFVC mode). If the AC drive is required to run at over
50 Hz, consider the capacity of the machine.
6) Vibration of mechanical device
The AC drive may encounter the mechanical resonance point at some output
frequencies, which can be avoided by setting the skip frequency.
7) Motor heat and noise
The output of the AC drive is pulse width modulation (PWM) wave with certain harmonic
frequencies, and therefore, the motor temperature, noise, and vibration are slightly
greater than those when the AC drive runs at power frequency (50 Hz).

5
8) Voltage-sensitive device or capacitor on output side of the AC drive
Do not install the capacitor for improving power factor or lightning protection voltage-
sensitive resistor on the output side of the AC drive because the output of the AC drive
is PWM wave. Otherwise, the AC drive may suffer transient overcurrent or even be
damaged.

9) Contactor at the I/O terminal of the AC drive

When a contactor is installed between the input side of the AC drive and the power
supply, the AC drive must not be started or stopped by switching the contactor on or off.
If the AC drive has to be operated by the contactor, ensure that the time interval
between switching is at least one hour since frequent charge and discharge will shorten
the service life of the capacitor inside the AC drive.
When a contactor is installed between the output side of the AC drive and the motor,
do not turn off the contactor when the AC drive is active. Otherwise, modules inside the
AC drive may be damaged.

the time interval is at least one hour . AC drive may be damaged .

10) When external voltage is out of rated voltage range

The AC drive must not be used outside the allowable voltage range specified in this
manual. Otherwise, the AC drive' s components may be damaged. If required, use a
corresponding voltage step-up or step-down device.
11) Prohibition of three-phase input changed into two-phase input
Do not change the three-phase input of the AC drive into two-phase input. Otherwise, a
fault will result or the AC drive will be damaged.

6
12) Surge suppressor
The AC drive has a built-in voltage dependent resistor (VDR) for suppressing the
surge voltage generated when the inductive loads (electromagnetic contactor,
electromagnetic relay, solenoid valve, electromagnetic coil and electromagnetic
brake) around the AC drive are switched on or off. If the inductive loads generate
a very high surge voltage, use a surge suppressor for the inductive load or also use
a diode.

Note

Do not connect the surge suppressor on the output side of the AC.

13) Altitude and de-rating

In places where the altitude is above 1000 m and the cooling effect reduces due to
thin air, it is necessary to de-rate the AC drive. Contact Hailing for technical support.
14) Some special usages
If wiring that is not described in this manual such as common DC bus is
applied, contact the agent or Hailing for technical support.
15) Disposal
The electrolytic capacitors on the main circuits and PCB may explode when they
are burnt. Poisonous gas is generated when the plastic parts are burnt. Treat
them as ordinary industrial waste.
16) Adaptable Motor
• The standard adaptable motor is adaptable four-pole squirrel-cage
asynchronous induction motor or PMSM. For other types of motor, select a
proper AC drive according to the rated motor current.
• The cooling fan and rotor shaft of non-variable-frequency motor are coaxial,
which results in reduced cooling effect when the rotational speed declines.
If variable speed is required, add a more powerful fan or replace it with
variable-frequency motor in applications where the motor overheats easily.
• The standard parameters of the adaptable motor have been configured inside
the AC drive. It is still necessary to perform motor auto- tuning or modify the
default values based on actual conditions. Otherwise, the running result and
protection performance will be affected.
• The AC drive may alarm or even be damaged when short-circuit exists on
cables or inside the motor. Therefore, perform insulation short-circuit test when
the motor and cables are newly installed or during routine maintenance.
During the test, make sure that the AC drive is disconnected from the tested
parts.

 Define communication data

This series of frequency converters support four communication protocols: Modbus RTU,
CANopen, canlink and PROFIBUS DP, user programmable card and point- to- point
communication are derived from canlink protocol. Through these communication protocols,
the upper computer can control and monitor the frequency converter and modify and view
the functional parameters.
Communication data can be divided into function code data and non function code data.
The latter includes operation command, operation status, operation parameters, alarm
information, etc.
1 Function code data

The function code data is an important setting parameter of the frequency converter. The
functional parameters of group F and group A are as follows:
Group P P0、P1、P2、P3、P4、P5、P6、

Group A A0、A1、A2、A3、A4、A5、A6、
data
(read/ write) A7、A8、A9、AA、AB、
AC、AD、AE、AF

The function code data communication address is defined as follows:

1. When reading function code data for communication

For P0 ~ PF and A0 ~ AF group function code data, the upper sixteen digits of the
communication address are directly the function group number, and the lower sixteen digits
are directly the serial number of the function code in the function group, for example:

P0-16 function parameters, and its communication address is P010H, where P0H
represents P0 group function parameters and 10H represents function code active
hexadecimal data format of serial number 16 in the group

AC-08 function parameter, its communication address is AC08, where ACH represents AC
group function parameter and 0 8 H represents function code active hexadecimal data in
sequence number group 8

2. When writing function code data for communication

For P0 ~ PF group function code data, its communication address is 16 digits high, which is
divided into 00 ~ 0F according to whether it is written to EEPROM or P0 ~ PF, the lower 16
digits are the serial number of the function code in the function group, for example:

Parameter writing function P16-P0

When EEPROM does not need to be written, its communication address is 0010H

When EEPROM needs to be written, its communication address is P010H

For A0 ~ AF group function code data, its communication address is 16 digits high.

According to whether it is necessary to write EEPROM, it is divided into 40 ~ 4F or A0 ~ AF,

83
 Define communication data
the lower 1 6 digits are the serial number of the function code in the function group, for
example:

Write function parameter AC-08

When EEPROM does not need to be written, its communication address is 4C08H

When EEPROM needs to be written, its communication address is AC08H

Group u parameter monitoring parameters

For the description of group u monitoring data, see relevant descriptions in Chapter 5 and
Chapter 6, and its address is defined as follows:

For U0 ~ UF, the upper sixteen digits of its communication address are 70 ~ 7F, and the
lower sixteen digits are the serial number of the monitoring parameters in the group, for
example:

U0-11, its communication address is 700bh

Fault description of frequency converter

When the communication reads the fault description of the frequency converter, the
communication address is fixed at 8000 h, and the upper computer can obtain the current
frequency converter fault code by reading the address data. See the definition of f9- 1 4
function code in Chapter V for the description of the fault code

Operation status of frequency converter

When the communication reads the operation status of the frequency converter, the

This function is required when it is necessary to initialize the parameters of the frequency
converter through the upper computer.

If PP-00 (user password) is not 0, first verify the password through communication. After the
verification is passed, the upper computer will initialize the parameters within 30 seconds.

Description of communication parameters of FD group

Baud rate initial value 6005

bit: Baud rate

Set range

This parameter is used to set the data transmission rate between the host computer and the frequency converter.
Note that the baud rate set by the host computer and the frequency converter must be consistent, otherwise,
communication cannot be carried out. The higher the baud rate, the faster the communication speed.

data format initial value

0: no check: data format < 8,N,2 >

1. even check: data format < 8,E,1 >
Set range
2. odd check: data format < 8,0,1 >
3: No verification: data format < 8 N -1 >

The data formats set by the host computer and the frequency converter must be consistent, otherwise,
communication cannot be carried out.

local address initial value

Set range 1~247, 0 is the broadcast address.

When the local address is set to 0, it is the broadcast address, which realizes the broadcast function of the upper
computer.
The local address is unique (except the broadcast address), which is the basis for realizing point-to-point
communication between the upper computer and the inverter.

89
 Response delay initial value

Set range

Response delay: refers to the interval between the end of data acceptance of the frequency converter and the
sending of data to the upper computer. If the response delay is less than the system processing time, the time shall
prevail; if the response delay is longer than the system processing time, the system processes it.
The response delay is processed by the system.
After the data is finished, it is necessary to delay waiting until the response delay time is up, and then send the
data to the upper computer.

Communication timeout initial value

invalid
Set range

When the function code is set to 0.0 s, the communication timeout parameter is invalid. When this function code is
set to a valid value, if the interval between one communication and the next communication exceeds the
communication timeout, the system will report a communication failure error (Er16). Usually it is set to invalid. If
the secondary parameters are set in a continuous communication system, the communication status can be
monitored. under

Communication protocol initial value

Set range 0: Non-standard Modbus protocol

1. Standard Modbus protocol

FD-05=1: Select the standard Modbus protocol.

FD-05=0: When reading a command, the number of bytes returned by the slave is one byte more than that of the
standard Modbus protocol.

Communication &current resolution initial value

Set range

Used to determine the output unit of the current value when the communication reads the output current.
