INVT GD200A 37KW

INVT GD200A 37KW General Purpose Vector Drive Overview

The INVT GD200A 37KW General Purpose Vector Drive is designed to control the speed, frequency and torque of compatible three-phase asynchronous motors. It belongs to the Goodrive200A general-purpose vector drive range and combines DSP-based processing with V/F and sensorless vector control.

The 37KW G-type rating is suitable for constant-torque industrial applications when the connected motor voltage, phase, rated current and load requirements remain within the drive’s operating limits. Its approximate motor equivalent is 50 HP, but motor selection must not be based on horsepower or kilowatt rating alone.

This invt vfd gd200a can manage gradual acceleration, controlled deceleration, variable-speed operation and stable motor performance under changing load conditions. It is suitable for properly engineered pump, fan, air-compressor, HVAC and industrial transmission systems.

Key Features and Benefits

V/F and Sensorless Vector Control

The drive supports V/F and sensorless vector control. V/F control is useful for standard variable-speed applications, while sensorless vector control provides improved speed and torque management without requiring a motor encoder in compatible installations.

Automatic Motor Tuning

Rotating and static motor auto-tuning options help match the control characteristics of the drive with the connected motor. Static tuning is useful where disconnecting the motor from the mechanical load is difficult. Rotating tuning can be selected when the application permits motor movement during commissioning.

Controlled Acceleration and Deceleration

Voltage and current control helps the drive respond to demanding acceleration and deceleration conditions. Correct ramp settings can reduce unnecessary mechanical shock and limit avoidable overcurrent or DC-bus overvoltage faults.

Multiple Frequency-Setting Methods

Operating frequency can be controlled through digital settings, analogue references, pulse-frequency input, multi-step speed settings, simple PLC functions, PID control and compatible communication settings.

PID Process Control

Built-in PID functionality supports applications requiring feedback-based control. A correctly configured pressure sensor, reference signal and control circuit can be used for constant-pressure water supply and other compatible process-control duties.

Smooth Speed Tracking

Speed-tracking functionality allows the drive to detect and smoothly restart a motor that may already be rotating. This feature is useful in selected fan and process applications where the motor does not immediately stop after the previous command.

Flexible Installation

The 37KW G-type unit supports wall and flange mounting. Correct clearances, ventilation, cabinet design and cable routing remain necessary for reliable heat dissipation.

Industrial EMC Filtering

A C3 EMC filter is built in for applicable industrial environments. An external C2 filter can be selected where the installation requires the corresponding EMC performance level.

Best For

The INVT GD200A 37KW drive is suitable for professionally designed applications such as:

• Industrial water pumps
• Constant-pressure water supply systems
• Ventilation and extraction fans
• HVAC equipment
• Air compressors
• Plastic-processing machinery
• Oil and petroleum-related equipment
• Mining and coal-industry machinery
• Water circulation systems
• Selected conveyors and process motors
• Standard industrial transmission loads

Final suitability depends on the motor nameplate, starting torque, operating current, duty cycle, braking requirements and machinery control method.

Not Ideal For

This VFD should not be selected for:

• A single-phase motor
• A motor with an incompatible rated voltage
• A motor whose current exceeds the drive’s permitted output
• Direct outdoor installation without a suitable protective enclosure
• Wet, dusty or corrosive locations without proper cabinet protection
• Applications requiring an encoder-based closed-loop control system
• Direct solar-panel input or built-in solar MPPT operation
• Loads requiring braking equipment that has not been correctly selected
• Safety-critical machinery without the required external safety system

The GD200A is a general-purpose AC vector drive. It must not be presented as a dedicated solar pump inverter because direct PV input and solar MPPT specifications are not established for this model.

Motor Compatibility

The drive is designed for compatible three-phase asynchronous motors. Its 37KW G-type rating is approximately equivalent to 50 HP.

A 37KW motor should not be connected based on power rating alone. Before installation, verify:

• Motor rated power
• Motor rated voltage
• Motor rated current
• Motor phase
• Motor frequency
• Motor speed
• Starting torque
• Load characteristics
• Overload demand
• Acceleration and deceleration time
• Braking requirements

The drive provides a rated output current of 75A in its 37KW G-type configuration. The motor’s nameplate current and operating demand must remain compatible with this limit.

Industrial Applications in Pakistan

The INVT GD200A 37KW VFD can help Pakistani factories, commercial facilities and agricultural operations regulate compatible motor-driven equipment according to actual demand.

In pump and fan applications, variable-frequency control can reduce unnecessary full-speed operation when the process does not need maximum output. Actual electricity consumption depends on the load profile, operating hours, system design and selected control settings. A fixed saving percentage should not be assumed.

For constant-pressure water systems, PID control can adjust motor speed in response to a correctly installed pressure-feedback signal. Industrial users can also integrate compatible analogue, digital, relay and communication signals into a wider control system.

Protection and Control Features

The GD200A platform provides more than 30 fault-protection functions. Major supported protections include:

• Overcurrent protection
• Overvoltage protection
• Undervoltage protection
• Overheating protection
• Phase-loss protection
• Motor and drive overload protection

The G-type overload capability includes:

• 150% of rated current for one minute
• 180% of rated current for ten seconds
• 200% of rated current for one second

These short-duration ratings do not permit continuous operation above the drive’s rated current. Correct motor sizing, parameter setup and load assessment remain essential.

Technical Specifications

Control Terminals and Communication

The drive provides analogue, digital, pulse and relay interfaces for integration with compatible control systems. It includes eight common digital inputs, one high-speed input, two analogue outputs, one high-speed pulse output, one open-collector output and two programmable relay outputs.

Frequency commands can be configured through supported digital, analogue, pulse, multi-step, PLC, PID, MODBUS and PROFIBUS control methods. The required communication hardware, wiring, protocol settings and control logic should be confirmed during system design.

Braking and Deceleration Requirements

The 37KW G-type configuration requires an optional external braking unit where dynamic braking is needed. The braking resistor is also external.

Braking equipment must be selected according to motor size, load inertia, stopping time and braking frequency. Incorrect resistor resistance, power rating or duty-cycle selection can damage the drive or connected braking components.

DC braking, flux braking and short-circuit braking functions may be used only where their operating characteristics suit the machine. High-inertia and frequently stopped loads require careful engineering.

Installation and Environmental Requirements

The IP20 enclosure is intended for installation inside a suitable electrical panel or protected indoor area. It does not provide outdoor, rain, water-jet or dust-tight protection.

Provide adequate ventilation and maintain the required installation clearances. Ambient temperature can range from -10°C to 50°C, but drive derating is required above 40°C.

Separate motor and control wiring where practical. Use proper earthing, correctly rated protection devices, suitable cable sizes and manufacturer-compatible input or output reactors when required by the installation.

Manual, Wiring Diagram and Parameter Setting

Use the product-specific invt gd200a manual when configuring motor data, control terminals, acceleration time, deceleration time, PID functions and fault handling. The invt gd200a user manual must match the Goodrive200A series and the installed voltage class.

The invt gd200a wiring diagram should be followed by a qualified electrical professional. Main-circuit wiring, control terminals, earthing, braking components and communication connections must be verified before power is applied.

Searches for invt gd200a manual pdf, invt gd200a user manual pdf download, invt vfd gd200a manual pdf, invt inverter gd200a manual and invt drive gd200a manual should lead to the correct GD200A documentation revision.

The phrase invt gd200 manual pdf download may return information for a different series. It must not replace the correct Goodrive200A material. Similarly, searches for manual inverter invt gd200a, invt vfd manual pdf free download or invt vfd parameter setting pdf free download should be checked carefully for the correct product series and voltage class.

Use the correct invt gd200a parameter setting procedure for the connected motor and application. Do not copy parameter values from another installation without checking the motor nameplate and load conditions. The invt gd200a catalog can be used to identify the applicable product family and accessories.
