Warning
1. The damaged inverter or the inverter lack of parts can’t be
installed.
Otherwise, danger of injury would be caused.
 Installing
Warning
1. When carrying, please hold the bottom of inverter
Only the panel is held, the inverter would fall off and such that you
would be injured.
2. Please install it on metallic plate not apt to be burned.
Install it on the flammable material, there would be fire caused.
3.If two or more inverters are installed in the same control
cabinet, please mount a fan and keep the air inlet temperature
at below 40 .
If too hot, there would be fire or other accidents caused.
 Connection
Danger
1. Please make sure the input power supply has been cut off
before connecting.
Otherwise, danger of electric shock and fire would be caused.
2. Lease invites electric engineering technicians to connect the
wire.
Otherwise, danger of electric shock and fire would be caused.
3. The earthing terminal must be earthed reliably.
(Class 380V: Suitable for earthing 3).
Danger of electric shock and fire would be caused.
-6-
4. After electrifying the emergency stop terminal, please check
the operation is available.
Otherwise, danger of injury would be caused. (The connection
responsibility is borne by user)
5. Please never touch output terminal directly, connect inverter
output terminal to enclosure, or give the short connection
among output terminals.
Otherwise, danger of electric shock and short circuit would be
caused.
Warning
1. Please make sure that AC main circuit power supply is
identical with the rated voltage of inverter.
Otherwise, danger of injury and fire would be caused.
2. Never conduct withstand voltage test for inverter.
Otherwise, damage of semiconducting elements would be caused.
3. Please connect the braking resistor or braking unit according
to diagram.
Otherwise, danger of fire would be caused
4. Please fasten the terminal by the screwdriver with specified
torque.
Otherwise, danger of fire would be caused.
5. Never connect the input power line to terminals U, V, W.
Such that, the voltage is applied to output terminal, the inner of
inverter would be damaged.
6. Never connect the phase-shift capacitor and LC/RC noise
filter to output circuit.
Otherwise, the inverter inner would be damaged.
7. Never connect electromagnetic switch and electromagnetic
contactor to output circuit.
When the inverter is running with the load, the surge current caused
by operation of electromagnetic switch and electromagnetic
contactor would cause over current protection circuit operation of
inverter.
8. Never disassemble the enclosure of front panel, but only
disassemble the enclosure of terminal when connecting.
Otherwise, the inner of inverter would be damaged.
-7-
 Maintaining and checking
Danger
1. Never touch the connection terminal of inverter as the terminal has
high voltage.
Otherwise, danger of electric shock would be caused.
2. Before electrifying, please install the terminal enclosure reliably, and
must cut off the power before disassembling the enclosure.
3. Laypeople are not allowed to maintain and check.
Warning
1. As CMOS integrated circuit is mounted on keyboard plate,
control circuit plate, driving circuit plate, please pay special
attention when using.
Once the circuit plate is touched by finger, the integrated chip on
circuit plate would be damaged for electrostatic induction.
2. In electrifying, never change the connecting wire or
disassemble the connecting wire of terminal.
In running, please never check the signal. Otherwise, the
equipment would be damaged.
1.3 Attentions of use
Please pay attention following points when using PR6000 series inverter.
Constant-torque and low-speed running
In case that the inverter with common motor runs at low speed for a long
time, the life of motor would be affected for the poor heat radiation. So if it is
needed low-speed&costant-torque long time running, professional inverter
must be choosed.
2 Confirmation of motor insulation
When using PR6000 series inverter with motor, please check up the
insulation of motor to protect equipment. In addition, if the motor is used in
1
-8-
the harsh environment, it is very necessary to check up the insulation of
motor regularly, so as to protect the safety of system.
3 Negative-torque load
The occasion that needs the load to be raised produces the negative
torque usually, the inverter would generate over current or over voltage fau lt,
and so it would trip, in case of this, a braking resistor shall be mounted.
4 Mechanical resonance point of load device
In the certain output frequency range, the inverter is likely to meet the
mechanical resonance point of load device, if that, the jumping frequency
must be set to avoid this point.
5 Capacitor or pressure sensitive element that improves power factor
If there is a capacitor or varistor for lightning protection that improves
power factor mounted on the output side, they shall be removed, otherwise,
the inverter would trip for fault or the parts would be damaged, because
output voltage of inverter is the type of impulse wave. In addition, on the
output side, it is suggested that air switch and contactor would not be
installed either, shown as diagram 1-3. (If the switch unit has to be mounted
on the side of output, the output current of inverter must be zero when the
switch operates.)

6
Derating use when setting basic frequency
When the basic frequency is lower than rated frequency, please pay
attention that the motor shall be derated; otherwise, the motor would be
damaged for over heat.
7 Run at over 50Hz.
If the inverter has to run at over 50Hz, the applicable speed range of
motor bearing and mechanical equipment must be guaranteed in addition to
considering the vibration and noise of motor, and please inquire before
inverter runs.
8 Electronic heat protection value of motor
-9-
When a motor chosen is applicable, the inverter can provide the motor
with heat protection. If the motor isn’t matchable with the rated capacity of
inverter, the protection value must be adjusted or other protection measures
must be taken, to guarantee the motor runs safely.
9
Altitude and derating use
If the inverter runs in area of over 1000m altitude, it must be derated by
reason that the heat radiation of inverter gets poor for rarefied air. Diagram
1-4 shows the relation between rated current of inverter and altitude.

1.4 Rejection attentions
Before scrapping the inverter, please pay attention following information:
When burning, the electrolytic capacitor of main circuit and electrolytic
capacitor of printed board are likely to explode, and the plastic part will
produce noxious gas. Therefore, the inverter shall be handled as the
industrial rubbish.

the cross screwdriver, i.e., the enclosure can be disassembled.
Install: Align the mounting screw, and then mount the screw.
3.3 Attentions of wiring
Warning
1 Before connecting, make sure the power supply has been cut off for more than
10min, otherwise, there would be electric shock danger.
2 Never to connect the power line to output terminals U,V,W of inverter.
3 Because there is leakage current in the inverter, the inverter and motor must be
grounded safely, the grounding wire shall be copper conductor of more than 3.5
mm², and the grounding resistance shall be less than 10Ω.
4 User shall not conduct the withstand voltage test for the inverter as it has passed this
test before leaving factory.
5 Between inverter and motor shall not be installed with the electromagnetic contactor
and absorbing capacitor or other resistance--capacitance absorbing implements as

RS232 communication wiring
(1) As is shown in diagram 3-12 multi inverters may be connected together by RS485
interface, they are controlled by PLC (or upper machine) that is used as master. And as
is shown in diagram 3-13 one inverter of them also can be used as master, and other
inverters are used as slave. With the addition of inverters, the communication is apt to
be interfered more easily, so we suggest the following connecting ways:

(All the inverter sand motors shall be earthed).
In case that aforementioned wiring can’t provide the normal communication, the following
measures may be tried.
(1) Supply the power for PLC (or upper machine) individually or isolate its power supply.
(2) Magnetic ring is used on the communicating wire; reduce the carrier frequency of inverter
properly.
3.7 Installation guide in line with EMC requirement.
Because the inverter outputs PWM wave, some electromagnetic noise will
be made when it operates, in order to prevent inverter interfering outside, this
section mainly introduces the methods of installing inverter EMC on the
aspect of noise suppression, field wiring, grounding, leakage current, power
filter and so on.

Solution
When the grounding wire of peripheral equipment with laying wire of inverter forms
the closed loop circuit, the leakage current of grounding wire will enable the
equipment to produce false operation. At this time, if the equipment isn’t earthed,
the false operation can be avoided.
When the power supply of peripheral equipment and power supply of inverter are
provided with the same system, the noise from inverter will transmit with inverting
the power line, thus, other equipment in the same system will be affected. The
following measures can be used to suppress the noise: Mount an electromagnetic
noise filter at input terminal of inverter; other equipment is isolated with isolating
transformer or power filter.
(1)The equipment and signal wire that is apt to be interfered shall be kept far from
the inverter. The signal wire shall be shielded wire. The single end of shielded layer
shall be earthed, and kept away the inverter and its input/output wire as far as
possible. If the signal wire must be crossed with heavy-current cable, they are must
be kept in quadrature.
(2)The roots of input/output side of inverter are installed with high-frequency noise
filter (common mode chock of ferrite), to suppress the radio frequency interference
of power line effectively.
(3)The cable of motor shall be put in the shield of large thickness, if installed in the
pipe of over 2mm or embedded into cement slot, the power line shall be covered in
the metallic pipe, and the shielded wire is used to earth (The motor cable shall be of
4 cores, one end is earthed on the side of inverter, the other is connected to
enclosure of motor. ).
Avoid heavy and light current conductors being laid in parallel or tied together, the
wiring shall be kept away from the installation equipment of inverter and
input/output wire as far as possible. The signal wire and power wire shall be the
shielded wire. The equipment with strong electric field or magnetic field shall be
kept a certain distance from the installation place of inverter or be kept in
quadrature.

(3)
Control signal line shall be shielded cable; the shielded layer is connected to PE
terminal of inverter, and earthed near the single end of inverter side.
(4)
The PE terminal grounding cable can’t be provided with other equipment earth wire, it
must be connected to grounding plate directly.
(5)
Control signal wire can’t be laid with cable of heavy current in parallel or in a near distance
( R, S, T or R T and U, V, W), and they can’t be tied together either, shall be kept over
20-60cm distance (relevant to strong current size). As is shown in diagram 3-12, they shall
be laid in vertical if need cross .As diagram 3-14
(6)
Light-current grounding wires like signal control line, sensor line and strong-current
grounding wire must be earthed independently.
(7)
Never connect other equipment to power supply input terminal (R, S, T or R, T) of
inverter.

Reverse run indicator light, indicates that the inverter indicator lights
output reverse phase order and the connected motor go on at the
rotates in reverse direction
same time.
When inverter occurs fault alarming, this light will go on.
4.2.4 Panel display state
PR-6000 keyboard display status is classified as stop parameter display
status, function code parameter editing status display, malfunction alarm
status display, and run status parameter display in total 4 kinds of status.
 Stop parameter display status
The inverter is in stop status and the status supervision parameter, usually
the setting frequency (b000) is displayed on keyboard. Unit is displayed by
rightward unit indicator light.
To press ►► key it can display different stop status supervision
parameters circularly(default b group of supervision parameter, for detail
please see b group status supervision parameter in function parameter
schedule graph of chapter 5). Pressing PRG , ▲ , ▼ to switch and
display status will be switched to constant supervision parameter
b000(namely set frequency) ,which is set by P063,displays automatically if
there is no key pressed within 1 minute.
 Run parameter display status
The inverter enters into run status when receiving effective run command
and run status supervision parameter normally output frequency (b000) is
displayed on the keyboard. Unit is displayed by rightward unit indicator light.
To press ►► key it can display different run status supervision
parameter circularly. Pressing PRG and ▲ , ▼ to switch and display
status will be switched to constant supervision parameter b000 (namely set
frequency), which is set by P063, display automatically if there is no key
pressed within 1 minute
- 35 -
 Failure alarm display status
The inverter enters into failure alarm display status upon detecting failure
signal and displays failure code sparklingly (as shown in Fig.4-5); To press
PRG
PRG enters into program mode to check b group parameter. It can be
carried on failure restoration by pressing key STOP
on the keyboard, control
RESET
terminal or communication command after troubleshooting. Keep displaying
failure code if failure exists continuously.
Diagram 4-5 Failure alarm display status
Warning For some serious failure, such as inverse module protection, over
current, over voltage etc., must not carry on failure reset forcibly to make the
inverter run again without failure elimination confirmed. Otherwise danger of
damaging the inverter would be caused.
 Function code editing status
Under waiting, run or failure alarm status, press PRG key, can enter into
editing status and editing status is displayed according to two classes’ menu
mode, as shown in diagram 4-6. The sequence is function code→ function
code parameter; pressing SET key can enter into one class by one class.
Under function parameter display status, to press SET key to carry on
parameter storage operation, to press PRG key can only come back to
upper class menu without storing modified parameter.

Description: under menu status, if the parameter has no flashing digit, this
function code can not be modified, possible reasons are as follows:
1 This function code is the parameter that is not amendable, for example,
actual detected status parameter, run record parameter etc.;
2 This function code can not be modified under run status and can be
changed after stopping running
3 When parameter is protected, all the function codes can not be modified.

Delay time of analog input signal
0.1 ~ 5.0 S
0.5S
The system filters analog signal input from external voltage input and external current
with the setting filter time constant, to remove the influence from interference signal.
The longer the time goes by, the stronger the interference resistance gets, in addition,
the control is quite stable, but the response is slower; on the contrary, the shorter the
time goes by, the more fast the response gets, but interference ability is poorer, and the
control may be unstable. In the practice use, if the best value can not be determined,
this parameter will be adjusted properly according to control and response situation.

The percentage of P146/P147 are all opposite to the max feedback quantity.
These parameters are used for setting closed-loop sleeping function.
The setting values of sleeping/waking threshold take the max feedback quantity as
the reference.
Sleeping process: When the inverter is in the closed-loop running state, if the
feedback quantity is always higher than the specified quantity, when the output
frequency of inverter falls to lower-limit frequency, and the feedback quantity is higher
than sleeping threshold, the inverter will time, and after P147 waiting sleeping time, it
will begin to decelerate to zero.
Waking process: When the feedback quantity is lower than waking threshold, the
inverter will start to time, and after P147 waiting sleeping time, it will perform PI
regulation and start closed-loop running.
If the lower frequency has been set, and sleeping condition is met, the inverter will
enter into the sleeping state at lower-limit frequency. And the function P145 P147 is
used to finish closed-loop sleeping function to realize energy-saving running.
