1.3Safety guidelines
1.3.1 Installation and maintenance precautions
Never do installation and maintenance works on the equipment, motor and motor
cables before disconnecting the power supply.
Only qualified persons are allowed to install and maintain the equipment.
If any maintenance work is required for sure, it can only be performed 25 minutes
after it is disconnected from the power supply and affirmed that the bus capacitor
inside the inverter has been completely discharged. Use a multimeter (1MΩ internal
resistance) to directly measure across inviter bus terminals (+) and (-) to confirm if the
inverter is completely discharged.
Do not touch control components of the inverter or external circuits connected with it,
as even when powering down the inverter, the external control circuit may cause

Goodrive3000 series medium voltage inverters Safety precautions
-5-
dangerous voltage inside the inverter.
Never perform insulation withstand voltage test directly on the terminals of the
inverter.
Before reconnecting the motor, please make sure the phase sequence of the motor
cable is correct.
So long as the inverter is powered on, whether it operates or not, there is
dangerous voltage on its terminals.
There is dangerous voltage over 1600V DC on the terminals (+) and (-) of the DC
bus.
There will be dangerous voltage on the output terminals of the relay. The
specific voltage level depends on the external circuits.
Do not refit Goodrive3000 series unauthorizedly; otherwise fire, electric shock or other
injury may occur.
The electrical parts and components inside Goodrive3000 series are electrostatic.
Take measures to avoid electrostatic discharge during relevant operation.
1.3.2 Grounding
Ensure good grounding of the inverter, motor and associated equipment to insure
personal safety under any conditions and effectively decrease the electromagnetic
radiation of the inverter.
Ensure the size of the grounding wire meets the requirement of applicable safety
regulations.
In the case of multi-cabinet connection, ensure independent grounding of each
cabinet.
In order to further decrease electromagnetic radiation, we suggest you to adopt
shielded cable and 360ºHF link, and connect the shielded wire directly to PE to meet
the safety requirement.
The shielding layer can be used as grounding wire only when its sectional area
meets the requirement of applicable safety regulations.
When the operating leakage current of the inverter is higher than 3.5mA (DC) or
10mA (AC), independent grounding must be used to ensure personal safety.
1.3.3Delivery and installation
As the equipment is heavy, do not move it alone. Do not move the equipment upside
down.
Ensure sufficient heat dissipation space for the equipment after installation.
Do not fix the inverter by riveting or welding.
1.3.4 Operation
Before starting the inverter, make sure the connected motor auxiliary devices meet
the operation speed requirements of the inverter. By adjusting the inverter, the
connected motor can run in the speed ranges higher than power frequency or lower
than power frequency.
If a dangerous situation exists, please do not activate the automatic fault reset
function as this function can enable the inverter, after a fault happens, reset fault
automatically and continue to operate.

3.2 Requirements for Goodrive3000 application
3.2.1 Requirements for storage environment
(1) The temporary storage environment must meet the requirements in the table below
Table 3-1 Requirements for temporary storage environment
Items
Specifications
Storage temperature
-40℃~70℃
It is required to avoid
condensation and icing
caused by sudden change
of temperature
Transport temperature
-10℃~50℃
Relative humidity
5~95%, even if the humidity meets the
requirement, the situations which can
cause condensation and icing due to
sudden temperature change cannot
yet meet the requirement
Atmosphere
The inverter should be stored in a place free of dust, direct sunshine,
flammable gasses, oil pollution, steam and vibration
(2) Requirements for permanent storage environment
If the inverter cannot be used at the moment due to change of project or other reasons after it is bought,
please store it by referring to the following instructions according to the specific situations.
The environment requirements for temporary storage must be met first of all. If the storage period
exceeds 3 months, the environment temperature must be controlled below 30℃. This is mainly because
the performances of the electrolytic capacitor inside the inverter will degrade if it is not powered.
Store the inverter with care to avoid intrusion of moisture. You can consider putting desiccant in the
packing box of the inverter to control the humidity inside the box below 70%.
If the inverter is installed inside a control cabinet or other equipment, especially on a construction site, it
will be in a moist and dusty condition. If it will not be used for a long period, we suggest you to remove it
and store in a place with a good environment.
The performances of the electrolytic capacitor will degrade if not used for a long period. When it is stored
long-term, we suggest you to electrify it at least once every year.

4.2 Keypad displaying
The keypad displaying state is divided into stopping state parameter, running state parameter and fault
alarm state and so on.
4.2.1Displayed state of stopping parameter
When the inverter is in the stopping state, the keypad will display stopping
parameters which is shown in figure.
In the stopping state, various kinds of parameters can be displayed. Select
the parameters to be displayed or not by the binary bit according to the
displayed parameter of stopping state. See the instructions for the detailed
definition of each bit in Chapter 5 P07.05 and Chapter 6 P07.07.
》/SHIFT can shift the parameters from left to right, QUICK/JOG can shift
the parameters from right to left.

4.2.2Displayed state of running parameters
After the inverter receives valid running commands, the inverter will enter
into the running state and the keypad will display the running parameters.
RUN/TUNE LED on the keypad is on, while the FWD/REV is determined
by the current running direction which is shown in figure.
In the running state, various kinds of parameters can be displayed. Select
the parameters to be displayed or not by the binary bit according to the
displayed parameter of stopping state. See the instructions for the
detailed definition of each bit in Chapter 5 P07.05 and Chapter 6 P07.05
and P07.06.
》/SHIFT can shift the parameters from left to right, QUICK/JOG can shift
the parameters from right to left.
4.2.3 Displayed state of faults
If the inverter detects the fault signal, it will enter into the fault pre-alarm
displaying state. The keypad will display the fault information. The TRIP
LED on the keypad is on, and the fault reset can be operated by the
STOP/RST on the keypad, control terminals or communication
commands.
If the fault continues, the keypad will keep displaying the fault
information.
4.2.4 Keypad setting and checking
Press SHIFT key and DOWN key for 3 seconds when power on. The keypad will enter the interface of
selection modes in the menu as follows:
1. Hardware test: test the buttons, display and whether the LED functions are normal or not.
2. Flash date program: be used when FLASH configuration table is updated.
3. Language select: can select Chinese and English.
4. Keypad SW ver: check MCU and Flash software version.
5. Converter Type Select: option 1: GD3000, other: reserved.
Goodrive3000 series Chinese mode is selected by default.
4.2.5 Displayed state of function codes editing
In the state of stopping, running or fault, press PRG/ESC to enter into the editing state (if there is a
password, see P07.00). Press DATA/ENT into the displayed state of function parameter. On this state,
you can press DATA/ENT to save the parameters or press PRG/ESC to retreat.
4.3 Keypad operation
Operate the inverter via keypad.
The inverter has three levels menu, which are:

1. Group number of function code (first-level menu)
2. Tab of function code (second-level menu)
3. Set value of function code (third-level menu)
Remarks: Press the PRG/ESC or the DATA/ENT can return to the second-level menu from the third-level
menu. The difference is: pressing DATA/ENT will save the set parameters into the control panel, and then
return to the second-level menu with shifting to the next function code automatically; while pressing
PRG/ESC will directly return to the second-level menu without saving the parameters, and keep staying
at the current function code.
Figure 4-2 Operation flow chart of three levels menu
Under the third-level menu, if the parameter has no flickering bit, it means the function code cannot be
modified. The possible reasons could be:
1) This function code is not modifiable parameter, such as actual detected parameter, operation records
and so on;
2) This function code is not modifiable in running state, but modifiable in stop state.

Chapter 5 Goodrive3000 series PWM
rectifier
Note: Chapter 5 is only for the rectifier of four-quadrant products.
5.1 Description of the PWM rectifier
The main circuit of PWM rectifier unit includes the LCL filter circuit, main contactor, buffer contactor,
buffer resistor, IGBT power modules and bus capacitors. Dual closed-loop control structure is also
applied. The outer loop is the bus voltage loop and the inner loop is the current loop. The reactive current
component of the input grid current can be controlled by the voltage phase detection and coordinate
transformation and regulation of PI regulator. When the controlled reactive current is 0, the power factor
of the rectifier can be close to 1 and the energy can flow in both directions.

Note: Q1 is the isolating changeover switch; the LCL filter consists of L1, C and L2; R0 is the power buffer
resistor; KM1 is the main contactor; KM2 is the buffer contactor and L3 is the output reactor.
PWM rectifier and converter can combine into the four-quadrant inverter. Goodrive3000 series rectifiers
can be used for potential loads, such as hoists, locomotive traction, oil pumping units and centrifugal
machines. In some large power applications, the four-quadrant inverters are needed to reduce harmonic
pollution to the grid. The inverter with PWM rectifier has the functions of four-quadrant operation, meeting
the requirements of speed regulation of various potential loads. It can transform the regenerative energy
of the motor into electric energy back to the grid and achieve high-efficiency energy saving in energy
feedback braking.
After the conversion of PWM rectifier, 3 phase AC current can be provided as DC current into the DC bus
and the DC circuit provides power to the motor. PWM rectifier monitors the control power before AC
power overvoltage, phase loss fault, IGBT module overtemperature, overcurrent, overload and
pre-charging. Rectifier unit will lock the pulse and send a fault single which can be reset after repowering
if fault occurs.
