Key Features
Advanced Vector Control
The GK310 uses open-loop vector control to provide accurate control of motor speed and torque. This makes the Vector Control AC Drive suitable for industrial equipment where stable low-speed operation, responsive acceleration, and consistent torque performance are important.
Strong Starting Performance
With 150% starting torque at 0.25Hz, the GK310 is designed to provide strong motor output during startup and low-speed operation. This capability is valuable for equipment that starts with a loaded motor or experiences changing torque requirements.
Flexible Motor Compatibility
The GK310 supports both asynchronous and synchronous motors, giving equipment designers greater flexibility when selecting the motor and drive combination.
High Overload Capability
The drive supports three levels of short-term overload performance: 150% for 1 minute, 180% for 10 seconds, and 200% for 0.5 seconds. This allows the High Performance AC Drive to handle demanding transient load conditions more reliably.
Compact Industrial Design
The book-type structure provides an efficient form factor for industrial control cabinets. Its compact construction supports flexible installation while helping make better use of available cabinet space.
Expandable Control Functions
The GK310 offers comprehensive I/O options and supports functional expansion cards. This allows the drive to be configured for different control requirements and integrated more easily into industrial automation systems.
Protection and Operational Reliability
Built-in protection functions help address common drive and motor operating conditions, including overcurrent, overvoltage, undervoltage, overheating, overload, and motor short-circuit detection.

Applications
The GK310 is designed for industrial equipment that requires stronger motor control performance than a basic general-purpose drive. Its vector control technology, starting torque, overload capability, and flexible control options make it suitable for applications where motor response and operating stability are important.
Material Handling
The GK310 AC Drives series can be used in material handling equipment where motors may experience changing loads during starting, conveying, and movement.
Textile Machinery
Textile machines often require stable motor speed and consistent torque during continuous production. The GK310 provides vector-based motor control for equipment with demanding speed regulation requirements.
Pump Systems
The GK310 can be applied to pump equipment requiring adjustable motor speed and reliable operation under changing operating conditions.
Industrial Machinery
The drive is suitable for machinery that requires accurate speed and torque control, particularly where compact cabinet installation and flexible motor compatibility are important.
Automated Production Equipment
With its open-loop vector control, comprehensive I/O, and expansion capability, the GK310 can be integrated into industrial automation equipment that requires configurable motor control.
Why Vector Control Matters in Industrial Applications
A conventional frequency drive can regulate motor speed by varying output frequency and voltage, while vector control provides a more precise approach to managing motor torque and speed. This makes a Vector Control AC Drive particularly useful for applications with demanding acceleration, low-speed torque, or changing load conditions.
For equipment requiring stronger dynamic response, the GK310 combines vector control with high starting torque and short-term overload capability. This positioning makes it a suitable High Performance Vector Control AC Drive for demanding industrial machinery rather than only basic speed-control applications.
Selecting the Right GK310 Model
When selecting a GK310 AC Drives model, the drive should be matched with the motor and the operating conditions of the application.
Important selection factors include motor type, rated motor current, input voltage, load characteristics, starting torque requirements, operating frequency, ambient temperature, installation altitude, and required control functions.
The available GK310 range covers different input voltage levels and output current requirements, allowing the series to be configured for a broad range of industrial equipment.
