the aging of the devices in the AC drive, which may cause potential faults or
reduce the service life of the AC drive. Therefore, it is necessary to carry out
routine and periodic maintenance.
(1) Routine maintenance involves checking:
• Whether the motor sounds abnormally during running
• Whether the motor vibrates excessively during running
• Whether the installation environment of the AC drive changes.
• Whether the AC drive's cooling fan works normally
• Whether the AC drive overheats
(2) Routine cleaning involves:
• Keep the AC drive clean all the time.
• Remove the dust, especially metal powder on the surface of the AC drive, to
prevent
the dust from entering the AC drive.
• Clear the oil stain on the cooling fan of the AC drive.

‐33‐
VM1000 Series
Do not reverse poles (+) and (-). Otherwise, it may damage the AC drive and even
cause a fire.
–– The cable length of the braking unit shall be no longer than 10 m. Use twisted
pair wire or pair wires for parallel connection.
–– Do not connect the braking resistor directly to the DC bus. Otherwise, it may
damage the AC drive and even cause fire.
C: Braking resistor connecting terminals (+)、PB
The connecting terminals of the braking resistor are effective only for the AC drive
of 22kw and configured with the built-in braking unit.
The cable length of the braking resistor shall be less than 5 m. Otherwise, it may

D: External reactor connecting terminals P、(+)
For the AC drive of 33 kW and above, it support external DC reactor. Remove the
jumper bar across terminals P and (+) and install the reactor between the two
terminals.
E: AC drive output terminals U, V, W
The capacitor or surge absorber cannot be connected to the output side of the AC
drive. Otherwise, it may cause frequent AC drive fault or even damage the AC
drive.
If the motor cable is too long, electrical resonance will occur due to the existance
of distributed capacitance. This will damage the motor insulation or generate
higher leakage current, causing the AC drive to trip in overcurrent protection. If
the motor cable is greater than 50m, an AC output reactor should be installed close
to the AC drive.
‐34‐
F: PE Terminal
This terminal must be reliably connected to the main earthing conductor and
resistance range must less than 0.1Ω. Otherwise, it may cause mal-function or even
damage to the AC drive.

(3)Wiring Standard of Control Terminal
According to the input signal and internal design of terminals, there are A, B, C
three conditions as following.
A: Analog input terminal
Weak analog voltage signals are easy to suffer external interference, and therefore
the shielded cable must be used and the cable length should be less than 20 m, as
shown in following picture2-17.In applications where the analog signal suffers
severe interference, install filter capacitor or ferrite magnetic core at the analog
signal source,as shown in following picture 2-18.

B:Digital Input Terminal
Generally, select shielded cable no longer than 20 m. When active driving is adopted,
necessary filtering measures shall be taken to prevent the interference to the power supply. It
is recommended to use mechanical contact input for control.
SINK Wiring
Figure 2-19 SINK Wiring
Sink wiring is the most commonly used wiring mode. To apply external power
supply, remove jumpers between +24 V and OP and connect the positive pole of
external power supply to OP and negative pole to COM.
‐41‐
VM1000 Series
Figure 2-20 Source Wiring
To source wiring, OP must be changed to connect to COM(for example by lug plate), and
connect +24v to public terminal of external controller.If using external power, it also
needs to connect the negative pole of external power to OP.
C:Digital Output Terminal
When the digital output terminal needs to drive the relay, an absorption diode shall
be installed between two sides of the relay coil. Otherwise, it may cause damage to
the 24 VDC power supply.
Do not reverse the polarity of the absorption diode during installation, as shown in
Figure2-21. Otherwise, the 24 VDC power supply will be damaged immediately
once there is digital output.

2.3 Electro Magnetic Compatibility
2.3.1 Eletromagnetic Interference and Installation Precautions
The electromagnetic interference includes two situations: one is electromagnetic
noise from the surroundings having interference on VFD; the other interference is
the interference to other equipment generating by VFD
Precautions:
(1)VFD and other electrical product should be well grounded.
(2)Try not to install the power input and output cables of the AC drive and
weak-current signal cables (such as control cable) in parallel. Install vertically if it
has conditions.
(3)It is recommended to use shield cable in the VFD output power or and the
shielding should be grounded completely.For the extension cable of interfered
equipment, it is suggested to use twisted shield cable and shielding should be well
grounded.
(4)If motor cable is longer than 50m, it requires to install output filter and reactor.
.
‐43‐
VM1000 Series
2.3.2 Solutions of Interfering VFD by Electromagnetic Equipment
Generally, the reason that VFD has an influence on electromagnetic is there are a large number
of relays, contactors, or electromagnetic brakes around VFD.When VFD is interfered and
malfunction, the following methods are recommended:
① Install a surge suppressor for the part that generates interference
②Install a filter at VFD intput side, refer to 2.3.5 for more details
③Use shield cables in VFD control signal line and detection cable, shielding should be well
grounded.
2.3.3 Solutions of interfering peripheral equipments by VFD
Noise in this part is classified into two kinds:One is VFD radiated interference;The other one
is VFD conducted interference. Both kinds of interference generate eletro magnetic and
electrostatic induction around the equipment, which result in equipment malfunction. Refer to
the following solutions according to various interference situations
(1)Generally the signal of meter, receiver and sensor etc for measuring is relatively
weak. If they are closed to VFD or in the same cabinet, it will cause interference and
malfunction to them easily.It is suggested to adopt the following solutions:Try to keep away
from the interference source;Do not arrange signal cable and power cable in parallel,especially,
do not tie together.Signal cable and power cable should use shield cable and ground
well;Install ferrite ring on VFD output side(suppressing frequency range from 30~1000MHz),
and coil 2 ~ 3 turns. For bad conditions, it can install an EMC output filter as option.
(2)When the equipment and VFD use same power, it will cause conducted interference. If the
solutions above can not eliminate interference, it needs to install EMC filter between VFD and
power (For model selection, refer to 2.3.5)
(3)Peripheral equipment ground independently, which can eliminate interference that caused
by leakage current of VFD ground cable when it is in common -ground.
‐44‐
VM1000 Series
2.3.4 Leakage Current and Handling
There are two forms of leakage current while using VFD: one is earth leakage current,the other
is leakage current between cable and cable.
(1)Factors that influenced earth leakage current and solutions
There exists distributed capacitance between wire and earth.The bigger the distributed
capacitance, the larger the leakage current.It can decrease the carrier frequency in order to
decrease leakage current. However, to decrease carrier frequency will increase motor noise.
Please note that the installation of the reactor is also an effective way to solve the leakage
current.
Leakage current increases with the loop current. When motor power is high, the corresponding
leakage current is high.
(2)The factors that caused leakage current between cable and cable and solutions
There exists distributed capacitance in VFD output circuits. It is likely to cause resonance and
bring about leakage current if the current in the circuits contains higher harmonics. If thermal
relay is put into use at this time, it will cause malfunction.
Solutions: decrease carrier frequency or install output reactor. When using VFD, it is suggested
to use its electronic overload protection, and do not install a thermal relay before the motor.
Precautions of installing EMC input filter at power input side
①Notes:Strictly comply with the ratings when using the EMC filter. The EMC filter is
category I electric apparatus, and therefore, the metal housing ground of the filter should be in
good contact with the metal ground of the installation cabinet on a large area, and requires good
conductive continuity. Otherwise, it will result in electric shock or poor EMC effect.
②As result of EMC test, it founds that the ground of the EMC filter and the PE conductor of
the AC drive must be tied to the same common ground. Otherwise, the EMC effect will be
affected seriously.
③The EMC filter should be installed as closely as possible to the power input side of the AC
drive.

4.5 Auto-tuning of Motor Parameters
Selection of vector control mode:Before the drive operates ,you must input the
exact nameplate parameters of motor, the standard motor parameters is equipped
with 8000H inverter according to parameters on the nameplate; vector control has a
high dependence on motor parameters.In order to get good control performance,it
must receive the correct parameters of controlled motor.
Procedures of motor auto tuning are as follows:
First, the control command source (F0.02) is selected as keypad.
Then input the following parameters according to the actual motor parameters
(according to the current motor selection):
F2.00: GP Type Display Selection
F2.01: motor rated power
F2.02: motor rated voltage
F2.03: motor rated current
F2.04: motor rated frequency
F2.05: motor rated speed
If the motor is completely disconnected from the load, select 2 in F2.11 (auto-tuning
completely), and then press the “RUN ”on the keypad , the VFD will automatically
calculate following parameter of the motor:
F2.06: asynchronous motor stator resistance
F2.07: asynchronous motor rotor resistance
F2.08: asynchronous motor leakage inductance
F2.09: asynchronous mutual inductance
F2.10: Motor no load current
The motor parameter automatic tuning above is completed
If the motor can not be completely disconnected with load, select 1 in the F2.11
(static auto tuning), and then press the RUN key on the keyboard.
‐62‐
If VFD will measure the stator resistance, rotor resistance and leakage inductance
instead of the mutual inductive reactance and load current,the user can calculate
these two parameters on their own according to the motor nameplate. The
parameters that used for calculating motor nameplate are: rated voltage U, rated
current I, rated frequency and power factor η:
The calculation methods of motor no-load current and motor mutual inductance is as
follows: Lσ indicates motor leakage inductance.
