Its built-in functions, including PID control, multi-step speed control, torque control, automatic voltage regulation, and comprehensive fault protection, help simplify motor system configuration and improve operating stability.
GK100 supports V/f control and sensorless vector control, allowing users to select a suitable control method according to the motor and application requirements. This makes the AC motor drive suitable for a wide range of general-purpose motor control tasks.
The drive provides 150% starting torque at 0.25 Hz under SVC control and 150% at 0.5 Hz under V/f control. This helps the motor start reliably when the application requires higher starting torque.
GK100 provides speed control precision suitable for general industrial motor applications. The available control modes help maintain stable motor operation under changing operating conditions.
The built-in PID control function allows the drive to regulate process variables such as pressure, temperature, and flow. This makes GK100 suitable for applications where motor speed needs to respond automatically to process conditions.
GK100 supports up to 16 multi-step speeds through its built-in PLC or control terminals. This function allows users to create different predefined operating speeds for machines with multiple working stages.
The automatic voltage regulation (AVR) function helps maintain stable output voltage when the input voltage fluctuates. This supports more consistent motor operation in applications with unstable power supply conditions.
The drive provides multiple protection functions, including over-current, over-voltage, under-voltage, overheating, phase loss, overload, and short-circuit protection. These functions help reduce the risk of drive and motor damage caused by abnormal operating conditions.
GK100 supports digital, analog, pulse, serial communication, multi-step speed, simple PLC, and PID-based frequency setting methods. These options provide flexible ways to control motor speed according to different machine requirements.

Choosing an AC motor drive requires more than matching the motor power rating. The drive should be selected according to the motor, load characteristics, operating environment, and required control functions.
Before selecting a drive, consider the following factors:
Check the motor type, rated voltage, rated current, power, and frequency to ensure compatibility with the selected AC motor drive.
Different loads require different control strategies. Fans and pumps typically have different operating characteristics from conveyors, compressors, and constant-torque machinery.
Determine whether the application requires V/f control, sensorless vector control, torque control, PID regulation, or other advanced control functions.
Consider the required operating frequency and speed range. The drive should provide sufficient control range for the machine’s normal operating conditions.
Applications with high inertia or frequent starting and stopping may require suitable acceleration, deceleration, braking, and protection functions.
For automated production systems, check whether the drive needs to communicate with PLCs, HMIs, or other industrial controllers. GK100 provides an RS485 interface with Modbus-RTU support.
Ambient temperature, humidity, altitude, ventilation, and installation conditions should also be considered when selecting and installing an AC motor drive.
An AC drive is a broad term for equipment used to control AC motor operation. A variable frequency drive (VFD) is a common type of AC drive that controls motor speed primarily by adjusting the output frequency and voltage.
