Preface
Goodrive300-01A series variable-frequency drive (VFD) for air compressors (hereinafter referred to
as GD300-01A VFD) is designed and optimized based on Goodrive300-01 to be applied in
synchronous/asynchronous air compressor for optimal control performance.
GD300-01A VFD carries the air compressor-specific control logic to connect to various signals of the
air compressor directly e.g. emergency-stop, pressure and temperature signals, fan transformer and
fault signals. It can realize control over solenoid valve and provide 24V power to HMI. It also carries
Modbus communication interface to fit the HMI without external controller or PLC, simplifying the
electrical design while realizing excellent variable-frequency control.
GD300-01A VFD has undergone compatibility test with multiple mainstream motor or master
manufacturers based on the application features and actual needs of air compressor industry. It
adopts dedicated PID and unique flux-weakening design to enable the air compressor to start quickly
and run smoothly with max driving frequency reaching 400Hz and above. Through high-power
density design and compact structure, it simplifies commissioning procedures and downgrades
product size. It adopts independent air duct, heavy-load and high power factor design to cope with
challenging field and grid environment.
GD300-01A VFD in the range of 7.5–15kW supports the built-in contactor units, low-frequency
transformer and low-frequency fan. It can provide 220V/110V power to supply the solenoid valve
(hereinafter referred to as GD300-01A single VFD integrated machine) and act as the extended
application of the small power of Goodrive300-21 dual VFD integrated machine, thus satisfying
diversified application needs of integrated machine.
Read this manual carefully before installation to ensure GD300-01A VFD can be installed and
operated correctly to give full play to its excellent performance.
If the end user is a military unit or the product is used for weapon manufacturing, please comply with
relevant export control regulations in the Foreign Trade Law of the People's Republic of China, and
complete necessary formalities.
Our company reserves the right to update the information of our products.

1.4 Safety instruction
Only well-trained and qualified personnel are allowed to operate on the VFD.
Do not carry out wiring, inspection or component replacement when the
power supply is applied. Ensure all the input power supplies are
disconnected before wiring and inspection, and always wait for at least the
time designated on the VFD or until the DC bus voltage is less than 36V. The
waiting time is shown as below.
VFD model
Minimum waiting time
380V
7.5kW–315kW
5 minutes
Do not refit the VFD unless authorized; otherwise, fire, electric shock or other
injuries may occur.
The base of the radiator may become hot during running. Do not touch to
avoid hurt.
The electrical parts and components inside the VFD are
electrostatic-sensitive. Take proper measurements to avoid electrostatic
discharge during related operation.
1.4.1 Shipment and installation
Install the VFD on fire-retardant material and keep the VFD away from
combustible materials.
Connect the optional brake parts (brake resistors, brake units or feedback
units) according to the wiring diagram.
Do not operate on the VFD if there is any damage or components loss to the
VFD.
Do not touch the VFD with wet items or body; otherwise, electric shock may
occur.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the VFD
and avoid physical injury or death. For physical safety, the installer must take mechanical
protective measures, such as wearing exposure shoes and working uniforms.
Ensure the VFD suffers no physical impact or vibration during moving and installation.
Do not carry the VFD by its front cover only as the cover may fall off.
Installation site must be away from children and other public places.
When the altitude exceeds 1000m, derate by 1% for every increase of 100m. When the altitude
exceeds 3000m, consult the local INVT dealer or office for details.
The application environment should be proper and appropriate.
Prevent the screws, cables and other conductive objects from falling into the VFD.
The leakage current of the VFD may be above 3.5mA during operation. Ground with proper

techniques and ensure the grounding resistor 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). For
models of higher than 30 kW, the cross sectional area of the PE grounding conductor can be
slightly less than the recommended area.
R, S and T are the power supply input terminals, while U, V and W are the output motor terminals.
Connect the input power cables and motor cables correctly; otherwise, damage to the VFD may
occur.
1.4.2 Commissioning and running
Disconnect all power supplies of the VFD before terminal wiring and wait for
at least the designated time after disconnecting the power supply.
High voltage is present inside the VFD during running. Do not carry out any
operation on the VFD except for keypad setting.
The VFD may start up by itself when P01.21=1. Do not get close to the VFD
and motor.
The VFD cannot be used as “Emergency-stop device”
The VFD cannot be used to brake the motor suddenly. A mechanical brake
device must be installed.
Note:
Do not switch on or off the input power supply of the VFD frequently.
For VFDs that have been stored for a long time, check and fix the capacitance and try pilot run
first before actual application.
Close the front cover before running the VFD; otherwise, electric shock may occur.
1.4.3 Maintenance and component replacement
Only well-trained and qualified professionals are allowed to carry out
maintenance, inspection, and component replacement of the VFD.
Disconnect all power supplies of the VFD before terminal wiring. Wait for at
least the time designated on the VFD after disconnecting the power supply.
Take proper measures to prevent screws, cables and other conductive
objects from falling into the VFD during maintenance and component
replacement.
Note:
Select proper torque to tighten the screws.
Keep the VFD and its parts and components away from combustible materials during
maintenance and component replacement.
Do not carry out any insulation voltage-endurance test on the VFD or measure the control circuit
of the VFD by megameter.
Take anti-static measures on internal parts during maintenance and component replacement.

1.4.4 Scrap treatment
There are heavy metals in the VFD. Treat with it as industrial effluent.
When the life cycle ends, the product should enter the recycling system.
Dispose of it separately at an appropriate collection point instead of placing it in
the normal waste stream.

132–315kW are the actually measured results in cases where there is no DC reactor; 15–110kW
is the actually measured result in cases where there is DC reactor.
Rated output current is defined as the output current under 380V output voltage.
