Preface
Thank you for choosing Goodrive270 series variable-frequency drive (VFD).
If not otherwise specified, the VFD in the manual always indicates Goodrive270 series VFD, which is
an optimized VFD special for fan and pump. Simple and easy to use, the VFD can drive the fans and
pumps in wastewater treatment, HVAC, chemical, metallurgical, electric power and other industries.
Using advanced vector control technologies, the VFD can drive both synchronous motors (SMs) and
asynchronous motors (AMs) in various complex work conditions. In addition, the VFD has been
embedded with various fan and pump application macros, such as PID, multi-pump control, constant
pressure water supply, effectively relieving engineers from the difficulty in debugging. The VFD uses
an independent air duct design and thickened circuit board coating, helping to adapt to hostile
environments, ensuring long and reliable run, and reducingmaintenance cost. The VFD also supports
communication bus add-on, such as CAN bus and PROFINET bus, providing better industrial control
system compatibility. The VFD power density is improved, facilitating the in-cabinet design and
reducing customer system costs. The VFD circuit optimization design has excellent electromagnetic
compatibility characteristics to ensure stable run in complex electromagnetic environments.
This manual instructs you how to install, wire, set parameters for, diagnose and remove faults for, and
maintain the VFD, and also lists related precautions. Before installing the VFD, read through this
manual carefully to ensure the proper installation and running with the excellent performance and
powerful functions into full play.
The manual is subject to change without prior notice.

Do not refit the VFD unless authorized; otherwise fire, electric shock or other
injury may result.
The base may become hot when the machine is running. Do not touch.
Otherwise, you may get burnt.
The electrical parts and components inside the VFD are electrostatic sensitive.
Take measurements to prevent electrostatic discharge when performing
related operations.
1.4.1 Delivery and installation
Do not install the VFD on inflammables. In addition, prevent the VFD from
contacting or adhering to inflammables.
Do not run the VFD if it is damaged or incomplete.
Do not contact the VFD with damp objects or body parts. Otherwise,
electric shock may result.
Do not push the VFD sidewards during moving.
Prevent the VFD from tipping sidewards.

and avoid physical injury or death. To ensure personal safety, take mechanical protective
measures like wearing safety shoes and working uniforms.

Goodrive270 series VFD for fan and pump Safety precautions
-3-
Protect the VFD against physical shock or vibration during the delivery and installation.
Do not carry the VFD only by its front cover as the cover may fall off.
The installation site must be away from children and other public places.
When the altitude exceeds 1000m, derate by 1% for every increase of 100m.
Use the VFD in proper environments. (For details, see section 4.2.1 Installation environment.)
Prevent the screws, cables and other conductive parts from falling into the VFD.
As leakage current of the VFD during running may exceed 3.5mA, ground properly and ensure
the grounding resistance is less than 10Ω. The conductivity of PE grounding conductor is the
same as that of the phase conductor (with the same cross sectional area).
R, S and T are the power input terminals, and U, V and W are the output motor terminals.
Connect the input power cables and motor cables properly; otherwise, VFD damage may occur.
1.4.2 Commissioning and running
Cut off all power supplies connected to the VFD before terminal wiring, and
wait for at least the time designated on the VFD after disconnecting the power
supplies.
High voltage presents inside the VFD during running. Do not carry out any
operation on the VFD during running except for keypad setup. The VFD control
terminals form extra-low voltage (ELV) circuits. Therefore, you need to prevent
the control terminals from connecting to accessible terminals of other devices
when there is no isolation protection mechanism configured.
The VFD may start up by itself when power-off restart is enabled (P01.21=1).
Do not get close to the VFD and motor.
The VFD cannot be used as an "Emergency-stop device".
The VFD cannot act as an emergency brake for the motor; it is a must to install
a mechanical braking device.
During driving a permanent magnet SM, besides above-mentioned items, the
following work must be done before installation and maintenance:
All input power supplies have been disconnected, including the main power
and control power.
The permanent-magnet SM has been stopped, and the voltage on output
end of the VFD is lower than 36V.
After the permanent-magnet SM has stopped, wait for at least the time
designated on the VFD, and ensure the voltage between + and - is lower
than 36V.
During operation, it is a must to ensure the permanent-magnet SM cannot
run again by the action of external load; it is recommended to install an
effective external braking device or cut off the direct electrical connection
between the permanent-magnet SM and the VFD.

1. Mechanical type of the load to be driven by the VFD to verify whether the VFD will be
overloaded during work. Whether the power class of the VFD needs to be increased.
2. Whether the actual running current of the motor is less than the rated current of the VFD.
3. Whether the control accuracy required by the load is the same as that is provided by the
VFD.
4. Whether the grid voltage is consistent with the rated voltage of the VFD.
5. Check whether expansion cards are needed for selected functions.
2.4 Environment checking
Check the following before installing the VFD:
1. Whether the actual ambient temperature exceeds 40°C. When the temperature exceeds
40°C, derate by 1% for every increase of 1°C. Do not use the VFD when the ambient
temperature exceeds 50°C.
Note: When the VFD is built in a cabinet, the ambient temperature is the temperature of air
in the cabinet.
2. Whether the actual ambient temperature is lower than -10°C. If the temperature is lower

than -10°C, use heating devices.
Note: When the VFD is built in a cabinet, the ambient temperature is the temperature of air
in the cabinet.
3. Whether the altitude of the application site exceeds 1000m. When the installation site
altitude exceeds 1000m, derate by 1% for every increase of 100m.
4. Whether the actual environment humidity exceeds 90% or condensation occurs. If yes, take
additional protective measures.
5. Whether there is direct sunlight or biological invasion in the environment where the VFD is
to be used. If yes, take additional protective measures.
6. Whether there is dust or inflammable and explosive gas in the environment where the VFD
is to be used. If yes, take additional protective measures.
2.5 Checking after installation
Check the following after the VFD installation is complete.
1. Whether the input power cables and motor cables meet the current-carrying capacity
requirements of the actual load.
2. Whether correct accessories are selected for the VFD, the accessories are correctly and
properly installed, and the installation cables meet the capacity carrying requirements of all
components (including the input reactor, input filter, output reactor, output filter, and DC
reactor).
3. Whether the VFD is installed on non-flammable materials and the heat-radiating
accessories (such as reactors) are away from flammable materials.
4. Whether all control cables and power cables are run separately and Whether the routing
complies with EMC requirement.
5. Whether all grounding systems are properly grounded according to the requirements of the
VFD.
6. Whether all the installation clearances of the VFD meet the requirements in the manual.
7. Whether the installation mode conforms to the instructions in the operation manual. It is
recommended that the VFD be installed uprightly.
8. Whether the external connection terminals of the VFD are tightly fastened and the torque is
appropriate.
9. Whether there are screws, cables, or other conductive items left in the VFD. If yes, get
them out.
2.6 Basic commissioning
Complete the basic commissioning as follows before the actual use of the VFD:
1. According to the actual motor parameters, select themotor type, set motor parameters, and
select the VFD control mode.

2. Check whether autotuning is required. If possible, de-couple the VFD from the motor load
to start dynamic parameter autotuning. If the VFD cannot be de-coupled from the load,
perform static autotuning.
3. Adjust theACC/DEC time according to the actual work condition of the load.
4. Perform device commissioning by means of jogging and check whether the motor rotational
direction is correct. If not, change the rotation direction by swapping any two phase wires of
the motor.
5. Set all control parameters and then perform actual run.
