INVT GD200A 7.5KW

INVT GD200A 7.5KW General Purpose Vector Drive Overview

The INVT GD200A 7.5KW General Purpose Vector Drive gives installers and industrial users adjustable control over the speed, frequency and torque of a compatible three-phase asynchronous motor. Its DSP-based control platform combines V/F operation with sensorless vector control, allowing the drive to serve standard transmission loads that need controlled acceleration, deceleration and operating speed.

The exact GD200A-7R5G/011P-4 model has two application ratings: 7.5KW in G-type duty and 11KW in P-type duty. The applicable rating must be selected based on the load category, current demand and overload requirement. The larger P-type figure must not automatically be treated as the correct rating for every machine.

The drive belongs to the 380V-class three-phase range and supports industrial applications such as air compressors, plastic machinery, HVAC systems, water-supply equipment, fans and pumps. It is a general-purpose AC motor drive rather than a solar MPPT pump inverter, so the power source, motor data and control method must be matched accordingly.

Key Features and Benefits

V/F and Sensorless Vector Control

The two control options allow installers to choose a suitable operating method for the connected motor and load instead of relying on basic fixed-frequency operation.

Rotating and Static Motor Auto-Tuning

Rotating auto-tuning supports applications that need higher control accuracy. Static auto-tuning can be used when the driven load is difficult to disconnect from the motor.

Low-Speed Vector Performance

Open-loop vector control supports responsive motor behaviour at low operating frequency when the motor information and control parameters have been configured correctly.

Automatic Voltage Adjustment

The drive regulates its output response during changes in input voltage, helping maintain more stable motor operation.

Speed Tracking

The speed-tracking function allows the drive to identify and smoothly restart a rotating motor where the application permits this operating method.

Flexible Frequency Commands

Frequency can be controlled through the keypad, analog inputs, pulse-frequency input, multi-step speed, simple PLC, PID control, Modbus or PROFIBUS when the required hardware and configuration are available.

Built-In Braking Unit

This model includes an internal braking unit. A correctly sized external braking resistor can be connected where the stopping time and load inertia require dynamic braking.

Integrated EMC Filtering

A built-in C3 filter supports industrial EMC requirements. An optional external filter can be selected for installations requiring C2-level filtering.

Practical Control Connectivity

Multiple digital, analog, pulse and relay channels support integration with switches, sensors, control panels, pressure-control systems and industrial automation equipment.

Best For

This INVT VFD is a practical option for compatible three-phase asynchronous motors used in:

• Ventilation fans
• Centrifugal pumps
• Water-circulation systems
• HVAC equipment
• Air compressors
• Plastic machinery
• Water-supply equipment
• Selected production machines
• Industrial automation panels
• PID pressure-control applications

The 7.5KW G-type rating is relevant where the load and overload requirements match that duty classification. The 11KW P-type rating should only be used where the application qualifies for P-type duty and the motor current remains within the relevant rating.

Not Ideal For

This drive is not suitable for a single-phase motor, a motor with incompatible voltage, or a machine whose current and overload demand exceeds the selected duty rating.

It should not be selected only because a motor nameplate shows 7.5KW. The motor voltage, phase, rated current, frequency, starting behaviour, braking requirements and load type must also match.

The drive is not intended for direct solar-panel input or MPPT-based solar pumping. Applications exposed to water, outdoor weather or heavy dust require a suitably designed electrical enclosure because the VFD itself carries an IP20 rating.

Safety-critical machinery and unusual loads may require application-specific engineering, external protection and commissioning by a qualified technician.

Motor Control and Speed Regulation

The drive produces an adjustable output from 0V up to the available input voltage and supports an output-frequency range of 0 to 400Hz. Actual operating limits must remain within the connected motor’s approved voltage, frequency, speed and cooling range.

Running a standard motor at low speed for extended periods can reduce its self-cooling. The thermal condition of the motor and driven equipment should therefore be considered during system design.

V/F control is suitable for many conventional fan, pump and general motor applications. Sensorless vector control provides more responsive speed and torque behaviour without an encoder when the correct motor information and auto-tuning process are used.

Acceleration and deceleration times should be adjusted for the load inertia to reduce avoidable overcurrent or DC-bus overvoltage trips.

Motor and Load Compatibility

Model GD200A-7R5G/011P-4 is intended for three-phase asynchronous motors. Its rated output current is 18.5A under the 7.5KW G-type rating and 25A under the 11KW P-type rating. The corresponding rated input-current figures are 25A and 32A.

These paired G-type and P-type values must not be mixed.

Motor suitability cannot be confirmed from kW alone. Check the following information before selecting the drive:

• Motor rated voltage
• Motor phase
• Full-load current
• Rated frequency
• Motor speed
• Motor insulation condition
• Motor connection arrangement
• Required starting torque
• Load inertia
• Braking frequency
• Acceleration and deceleration requirements
• Operating environment

Also determine whether the driven equipment is a constant-torque, variable-torque, high-inertia or frequently stopped application. Cable length, switching frequency, ambient temperature and enclosure ventilation can also affect the final installation.

Pump, Fan and Water-Supply Applications

The GD200A platform can control compatible pumps and fans where adjustable speed is used to manage pressure, flow or airflow.

PID control can be integrated with a pressure reference from an analog input or keypad. Relay outputs may also be configured for auxiliary equipment in an engineered water-supply control system.

For a pump installation, confirm the motor current, pump curve, required head, water flow, pipe losses and allowable operating speed. For fans and HVAC equipment, verify the motor duty and minimum safe speed.

This model does not provide solar MPPT operation. A pump or fan installation must therefore use a compatible AC supply and correctly designed control system.

Industrial Applications in Pakistan

In Pakistan, this drive can be used in compatible factory and commercial installations for air compressors, ventilation systems, water circulation, process pumps, HVAC equipment, plastic machinery and selected standard transmission loads.

Adjustable motor speed helps machinery deliver the operating point required by the process. Actual results depend on correct VFD sizing, motor condition and parameter configuration.

Sites experiencing fluctuating supply conditions still need proper electrical protection, earthing and cable selection. The installation should also account for ambient heat, dust and control-panel ventilation.

The supported operating-temperature range is -10°C to 50°C, with derating required above 40°C. Enclosure and cooling design are therefore especially important in hot production areas.

Protection and Control Features

The GD200A provides more than 30 fault-protection functions. Supported protection categories include:

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

Voltage and current control functions can adjust the output frequency during acceleration or deceleration to reduce avoidable trips. These functions do not replace correct motor sizing and upstream electrical protection.

The drive also supports automatic voltage adjustment, speed tracking and multiple braking methods. Dynamic-braking applications require an external braking resistor selected for the actual load energy and stopping cycle.

Incorrect resistor selection or excessively frequent braking can damage equipment. Braking design should therefore be completed by a qualified professional.

Installation and Wiring Notes

The drive must be installed inside a suitable control panel with adequate clearance and airflow. Keep power cables separated from low-voltage signal wiring and use proper protective earthing.

Follow the correct R/S/T input and U/V/W motor-output connections. Never connect the incoming AC supply to the motor-output terminals.

Select upstream protection, cable size, contactors, reactors, EMC components and braking resistance for the site conditions and applicable electrical standards.

The invt gd200a wiring diagram should be checked before terminating the main-circuit and control-board terminals because these terminals perform different functions. Isolate the supply and allow the DC bus to discharge before working on the drive.

Installation and commissioning should only be performed by a qualified technician familiar with VFDs and the connected machinery.
