Goodrive300-21 Series Dual-inverter
Integrated Machine for Air Compressor

Goodrive300-21 integrated machine for air compressor Preface

Preface
Goodrive300-21 series dual inverter integrated machine for air compressor (hereafter referred to as
GD300-21 air compressor integrated machine) is especially developed for
synchronous/asynchronous twin screw air compressor. It can be used in combination with HMI touch
screen to drive and control the twin screw air compressor.
GD300-21 air compressor integrated machine is capable of providing dual inverter output of master
and fan for the air compressor as well as offering +24V power to the touch screen. It supports control
of solenoid valve and receiving of temperature and pressure signal. In respect of function, it is a
perfect replacement for the original dual inverter electrical control cabinet of air compressor but with a
much smaller size and simpler installation and commissioning procedures.
Given the application scenarios and actual demands of air compressor, GD300-21 air compressor
integrated machine can realize fast start-up and stable operation of air compressor through dual PID
and unique weak magnetic design. It adopts independent air duct, heavy load and high power factor
design to effectively cope with challenging grid conditions and application environment. In addition, it
can realize IOT application by installing optional parts and accessories.
Read through this manual carefully before installation to ensure correct installation and operation of
GD300-21 air compressor integrated machine, thus giving full play to its excellent functions and
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.
The manual is subject to change without prior notice.

Note:
1. Do not use asymmetrical motor cables. Do not use asymmetrically constructed motor cable. If
there is a symmetrically constructed ground conductor in the motor cable in addition to the
conductive shielding layer, ground the ground conductor at the inverter end and motor end.
2. Route the motor cable, input power cable and control cable separately.
3. Before powering on the system, ensure that U1/V1/W1 or U2/V2/W2 are not short-circuited to PE
on the output side. Otherwise, tripping may occur on the power distribution cabinet when the
system is being powered on.

Note: The solid line represents the recommended wiring diagram which carries the least wiring for
ensuring system operation. The dotted line represents the wiring diagram used when discrepancy
occurred to the configuration of integrated machine.
4.2 Recommended wiring process
The terminal layout of 15–22kW, 30kW–37kW and 45–90kW slightly differs from each other. 15–
22kW and 45–90kW are taken as examples for wall-mounting wiring.

Note:
1. There are two controlling cable through holes on the top and at the bottom of the integrated
machine cabinet, users can select which through-hole to use based on wiring condition. It is
recommended that the controlling cable is routed via top through-hole to realize separation
between controlling cable and motor cable and reduce interference. The motor temperature
detection or temperature protection cable which follows the motor power cable can be routed via
bottom through-hole.
2. Refer to B.4.3 Installation diagram of optional pedestal for floor installation layout.
4.3 Function commissioning procedure
It is recommended that GD300-21 air compressor integrated machine adopt touch screen for
displaying and commissioning. The concrete procedures are listed as follows: (if other controllers are
used, contact our technician)
1. Conduct wiring and routing according to “4.1 Wiring diagram of integrated machine system” and
“4.2 Recommended wiring process“; check carefully if the wiring is correct and ensure the
integrated machine and its shell GND is properly connected.
2. After power on, the touch screen HMI interface is shown as follows:
