AP-GT21-30/1629P(01) Application Field and Working Principle

AP-GT21-30/1629P(01) - otherwise known as GT21 - is an integrated, multi-function motor drive module developed for motor control applications. It is a module made up of several components that act as a unit. This module can control motors in a wide range of applications such as industrial networks and machine automation. This article will discuss the GT21’s application field and working principles.

Application Field

The GT21 is widely used in various types of motors, such as AC, DC Brushless, and Synchronous Motors. It is often used for high precision and high torque applications such as robots and CNCmachines. In addition, the GT21 can be used with various communication protocols, such asProfibus, Ethernet, serial, and CANopen. This makes the GT21 suitable for motors with different communication requirements.The GT21 also has two different configurations that provide options for different applications. Thestandard configuration provides the ability to control up to four three-phase, two-wire AC motors witha single module. The advanced configuration can handle up to four AC motors or up to four DCbrushless motors with two modules.

Working Principle

The GT21 is designed to provide excellent speed and torque control in a wide variety of applications. It features a Sensorless Vector Control (SVC) algorithm, which uses an internal model to estimate the motor’s operating characteristics. This allows for precise and accurate speed control.The GT21 also has a wide speed range (up to 6000 rpm) and torque output up to 140 Nm. In addition, it can operate in either open loop or closed loop control modes. In open loop control, the desired speed is set by the user and the controller’s internal algorithms maintain the speed. In closed loop control, the actual motor speed is monitored and the controller adjusts its output accordingly.The GT21 can also be used for soft-start and coast-down control. This prevents sudden surge of the motor’s current and ensures smooth startups and stops. The controller also includes safety features, such as voltage monitoring, current limiting, and a stall protection circuit. In conclusion, the GT21 is a versatile motor drive module that provides precise speed and torque control for various types of motors. It is suitable for a variety of applications, from industrial networks and machine automation to household devices. The GT21’s features make it a suitable choice for many motor control applications.
