Preface
Goodrive300-01A series variable-frequency drive (VFD) for air compressors (hereinafter referred to
as GD300-01A VFD) is designed and developed by INVT based on the requirements of the air
compressor industry, which can be applied in the control of synchronous/asynchronous air
compressor. The product supports an optional multi-function expansion card, which is suitable for air
compressor control that requires more functions.
Goodrive300-01A 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 current
transformer and fault signals. It can provide 24V power to HMI. It also carries RS485 communication
interface of standard Modbus protocol 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. 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.
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 product is ultimately used for military affairs or weapon manufacture, comply with the export
control regulations in the Foreign Trade Law of the People's Republic of China and complete related
formalities.
Our company reserves the right to update the information of our products without prior notice.

Do not perform wiring, inspection or component replacement when power
supply is applied. Ensure that 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.

Do not refit the VFD unless authorized; otherwise fire, electric shock or other
injury may result.
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 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.
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. To ensure personal 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.
The application environment should be proper and appropriate.

Goodrive300-01A series VFD for air compressor Safety precautions
-3-
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 and wait for
at least the designated time 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.During maintenance and component replacement, take
measures to prevent screws, cables and other conductive matters from
falling into the internal of the programmable controller.
Note:
Use proper torque to tighten screws.
Keep the VFD and its parts and components away from combustible materials during

Goodrive300-01A series VFD for air compressor Safety precautions

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 the VFD and 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.

Note:
Rated input current is the actually measured result under 380V input voltage. Input current of
7.5–11kW and 132–315kW VFD models is the actually measured results in cases where there
is no DC reactor. Input current of 15–110kW VFD models is the actually measured result in
cases where there is DC reactor. Input current of 350–500kW VFD models is the actually
measured result under 380V input voltage with input reactor.
Rated output current is defined as the output current under 380V output voltage.
Under the allowable input voltage range, the output current shall not exceed its rated output
current, and the output power also shall not exceed its rated output power.

Note:
Input current of 22–350kW VFD models is the actually measured result under 660V input
voltage without DC reactor and input/output reactor.
Input current of 400–630kW VFD models is the actually measured result under 660V input
voltage with input reactor.
Rated output current is defined as the output current under 660V output voltage.
Under the allowable input voltage range, the output current shall not exceed its rated output
current, and the output power also shall not exceed its rated output power.
