INVT GD200A 4KW General Purpose Vector Drive Overview

The INVT GD200A 4KW is a high-performance general-purpose VFD for controlling the speed, torque, acceleration and stopping behaviour of compatible three-phase asynchronous motors. It uses DSP-based control with V/F and sensorless vector control technologies to support stable motor operation under different load conditions.

Buyers searching for invt gd200A or invt gd200a often require a dependable drive for pumps, fans, compressors, HVAC systems, plastic machinery and other standard industrial transmission loads. This model provides a practical combination of motor-control performance, programmable inputs and outputs, protection functions and communication support.

A VFD does more than switch a motor on and off. It adjusts the motor frequency and output voltage according to the required operating speed. This can improve process control, reduce mechanical stress during starting and help the motor respond more smoothly to changing application requirements.

The GD200A is a general-purpose vector drive. It should not be treated as a dedicated solar pump inverter with built-in solar MPPT. Any DC supply or solar-related application requires project-specific electrical design and confirmation of the permitted input arrangement before installation.

Key Features and Benefits

V/F and Sensorless Vector Control

The drive supports conventional V/F control and sensorless vector control. V/F mode is useful for many standard variable-speed applications, while sensorless vector control provides improved speed and torque performance where more responsive motor operation is required.

Accurate Motor Auto-Tuning

Rotating and static motor auto-tuning options help the drive identify important motor characteristics. Static tuning is useful when the motor cannot be disconnected from the load, while rotating tuning can be selected where the application permits the motor to rotate safely during commissioning.

Stable Voltage and Current Control

The GD200A manages voltage and current during acceleration and deceleration to reduce unnecessary overcurrent and DC-bus overvoltage trips. Correct acceleration, deceleration and motor parameters remain essential for dependable operation.

Flexible Frequency Setting

The operating frequency can be controlled through digital settings, analogue inputs, pulse frequency, multi-step speed settings, simple PLC functions, PID control or Modbus communication. This flexibility supports both local keypad operation and integration with an external automation system.

Multiple Braking Functions

Dynamic braking, DC braking, flux braking and short-circuit braking functions are available for suitable applications. This 4KW model includes a built-in braking unit, while an external braking resistor must be selected according to the load, stopping time and braking duty.

Extensive Protection

The drive provides more than 30 fault-protection functions, including protection against overcurrent, overvoltage, undervoltage, overheating, phase loss and overload. Proper earthing, enclosure design, cable selection and parameter configuration are still required.

Communication and Control Integration

Modbus communication, programmable digital inputs, analogue inputs, analogue outputs, relay outputs and high-speed pulse functions allow the VFD to work with compatible sensors, controllers and automation equipment.

Best For

The INVT GD200A 4KW can be considered for properly matched applications such as:

• Centrifugal pumps
• Water-circulation systems
• Ventilation and exhaust fans
• HVAC equipment
• Air compressors
• Plastic machinery
• Constant-pressure water-supply systems
• Selected conveyors
• Oil-industry equipment
• General industrial process motors
• Standard variable-speed transmission loads

Final selection must consider the motor nameplate, load type, starting torque, overload demand and operating environment.

Not Ideal For

This VFD is not suitable where:

• The motor exceeds the drive’s rated power or output current.
• The motor voltage or phase arrangement is incompatible.
• A single-phase motor is being used without verified compatibility.
• The installation requires a higher enclosure protection rating than IP20.
• The equipment will be exposed directly to water, dust or harsh contaminants without a suitable control cabinet.
• A dedicated solar pump inverter with integrated MPPT is required.
• The application requires regenerative operation or a braking arrangement that has not been properly engineered.
• The load needs specialised control characteristics beyond a general-purpose vector drive.

Motor Compatibility and Correct Sizing

The INVT GD200A 4KW is intended for compatible three-phase asynchronous motors. Its rated output power is 4KW in G-duty operation, with a rated output current of 9.5A.

Motor compatibility must not be decided from the 4KW rating alone. Check the motor’s rated voltage, current, frequency, phase, speed, connection method, load type and required starting torque. The motor nameplate current should remain within the VFD’s applicable output limits.

The drive offers G-type overload capability of 150% rated current for one minute, 180% for ten seconds and 200% for one second. These ratings do not permit permanent oversizing of the connected motor or operation beyond the drive’s continuous current limit.

Industrial and Water-Supply Applications

The GD200A can regulate compatible pumps and fans by adjusting motor speed according to process demand. Its PID function and analogue feedback capability support properly engineered constant-pressure water-supply systems.

For industrial machinery, controlled acceleration and deceleration can reduce abrupt mechanical shocks compared with direct-on-line starting. Sensorless vector control can also provide better load response in applications that require more precise speed and torque behaviour.

Pump performance, water flow and pressure cannot be calculated from the VFD rating alone. A complete water-pumping design requires the pump curve, motor data, total dynamic head, required flow rate, pipe size, cable length and site conditions.

Protection and Control Features

The drive supports the following protection and control functions:

• Overcurrent protection
• Overvoltage protection
• Undervoltage protection
• Overheating protection
• Phase-loss protection
• Motor overload protection
• Automatic voltage adjustment
• Speed tracking for a rotating motor
• PID control
• Multi-step speed operation
• Simple PLC operation
• Analogue and digital control inputs
• Programmable relay outputs
• Modbus communication
• Dynamic, DC, flux and short-circuit braking functions

Protection settings must be configured according to the connected motor and application. A VFD cannot compensate for incorrect wiring, poor earthing, an unsuitable motor or an undersized electrical installation.

Installation, Wiring and Parameter Settings

Installation should be completed by a qualified electrical technician. Keep the power and control wiring separated, provide reliable earthing and select protective devices and cables according to the supply, motor current and applicable electrical requirements.

The invt gd200a wiring diagram should be followed carefully for the main circuit and control terminals. Never connect incoming AC power to the VFD output terminals. Before working on the drive, isolate the power and allow the DC bus to discharge fully.

Correct invt gd200a parameter setting begins with verified motor nameplate data. Enter the motor’s rated power, voltage, current, frequency and speed before performing an appropriate auto-tuning procedure. Acceleration, deceleration, minimum frequency, maximum frequency and protection settings should match the actual load.

Manual, Catalogue and Technical Resources

The invt gd200a manual should be matched with the exact series and voltage class before commissioning. An invt gd200a manual pdf can help technicians review terminal functions, parameter groups, fault codes and commissioning procedures.

When searching for invt gd200a user manual or invt gd200a user manual pdf download, confirm that the document covers the GD200A series and is obtained from a reliable source. A mismatched manual can lead to incorrect terminal connections or parameter values.
