INVT GD200A 18.5KW

INVT GD200A 18.5KW General Purpose Vector Drive Overview

The INVT GD200A 18.5KW General Purpose Vector Drive is designed to regulate the operating speed, frequency, and torque of compatible three-phase asynchronous motors. It belongs to the Goodrive200A high-performance general-purpose vector drive range and combines DSP-based control with V/F and sensorless vector control technologies.

The drive accepts a three-phase AC supply and converts it into a controlled variable-frequency output for the connected motor. This allows the motor to operate at the speed required by the application instead of remaining limited to fixed mains frequency operation.

Accurate speed control can improve process stability, reduce mechanical stress during starting and stopping, and provide better control over pumps, fans, compressors, and other standard transmission loads. Correct motor and application sizing remains essential because power rating alone is not sufficient for selecting a VFD.

Key Features and Benefits

V/F and Sensorless Vector Control

The drive supports standard V/F control and sensorless vector control. V/F control is suitable for many conventional pump, fan, and general motor applications. Sensorless vector control provides better motor response where more accurate speed and torque regulation is required without installing a separate motor encoder.

Accurate Motor Auto-Tuning

Rotating and static motor auto-tuning options help the drive identify important motor characteristics. Rotating auto-tuning can be used when the motor can be separated safely from its mechanical load. Static auto-tuning is useful when disconnecting the load is difficult.

Strong Overload Capability

The G-type overload ratings include:

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

The actual operating load, acceleration time, duty cycle, ambient temperature, and motor current must remain within the drive’s permitted limits.

Flexible Frequency Setting

Operating frequency can be controlled through digital settings, analogue inputs, pulse-frequency input, multi-step speed settings, simple PLC operation, PID control, Modbus communication, or PROFIBUS communication settings.

This flexibility allows the VFD to work with control panels, pressure sensors, PLC systems, external potentiometers, and selected automation equipment when properly configured.

Smooth Speed Tracking

Speed-tracking functionality helps the drive restart a motor that is already rotating. This can be useful for fans and other applications where the motor may continue spinning after the power supply or run command is interrupted.

Built-In Braking Unit

This 18.5KW model falls within the range equipped with a built-in braking unit. An external braking resistor may be installed where the application requires faster deceleration or stronger braking. The resistor rating must be selected according to the load inertia, braking torque, and braking frequency.

Convenient Keypad Operation

The 18.5KW power class supports a detachable LED keypad arrangement. Parameter upload and download support makes repeated configuration and maintenance work more convenient. An optional LCD keypad with English display support can also be considered where required.

Best Applications

The INVT GD200A 18.5KW VFD is suitable for correctly matched applications such as:

• Air compressors
• HVAC equipment
• Ventilation and extraction fans
• Water circulation systems
• Centrifugal pumps
• Pressure-control systems
• Plastic processing machinery
• Petroleum industry equipment
• Mining and coal industry equipment
• Heating and water-supply systems
• Selected conveyors
• General industrial transmission loads
• Compatible process machinery

Application suitability must be checked against the motor nameplate, starting torque, rated current, duty cycle, control method, and operating environment.

Not Ideal For

This VFD should not be selected for:

• Motors exceeding its supported power or current limits
• Motors with an incompatible rated voltage
• Single-phase motors requiring a single-phase motor output
• Direct solar-panel input or applications requiring solar MPPT control
• Outdoor installation without a suitable protective enclosure
• Locations where dust, water, or contamination exceeds IP20 protection
• Applications requiring encoder-based closed-loop control
• Systems requiring specialised regenerative operation without appropriate engineering
• Motors or machinery with control requirements outside the drive’s supported characteristics

Motor Compatibility

The drive is intended for compatible three-phase asynchronous motors. Its general-duty G rating is 18.5KW, with a rated output current of 38A.

Do not select the VFD only by comparing the motor’s kilowatt rating. Before installation, verify:

• Motor rated power
• Motor rated voltage
• Motor rated current
• Motor frequency
• Number of motor phases
• Motor type
• Starting torque requirement
• Continuous and intermittent load demand
• Acceleration and deceleration time
• Required operating speed range
• Environmental temperature
• Braking requirements

A motor with an unusually high rated current or heavy starting load may require a different drive selection even when its nominal kilowatt rating appears compatible.

Industrial Applications in Pakistan

The INVT GD200A 18.5KW can be used in Pakistani industrial and commercial facilities operating compatible three-phase machinery. It is suitable for applications that need adjustable motor speed, controlled starting, pressure regulation, or automated frequency control.

Common installations include factories, commercial buildings, workshops, water circulation systems, ventilation plants, and production facilities. Pump and fan applications can use PID control with appropriate external feedback equipment to maintain pressure or another process value.

Site voltage quality, ventilation, enclosure design, dust, moisture, cable length, motor insulation, and earthing should be evaluated before commissioning.

Protection and Control Features

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

• Overcurrent protection
• Overvoltage protection
• Undervoltage protection
• Overheating protection
• Input or output phase-loss protection
• Motor and drive overload protection

The drive also adjusts output frequency during certain acceleration and deceleration conditions to reduce unnecessary overcurrent and DC-bus overvoltage trips.

Automatic voltage adjustment helps maintain stable motor operation when the incoming grid voltage changes within the supported operating range.

Installation and Wiring Guidance

A qualified VFD technician should install and commission the drive. The incoming three-phase supply, motor cable, protective earth, control wiring, external braking resistor, and optional reactor or filter must be connected according to the correct INVT GD200A wiring diagram.

Keep control and power wiring separated where practical. Use suitable circuit protection, cable sizes, earthing, and enclosure ventilation. Confirm the motor direction at a safe frequency before operating the machine at normal speed.

The VFD must be isolated from the power supply before wiring, maintenance, or inspection. Allow sufficient time for the DC bus to discharge and verify the voltage before touching internal terminals.
