Delta servo drives are components used in motion control systems to precisely control the speed, position, and torque of servo motors. Delta Electronics, Inc. is a multinational company that manufactures a variety of industrial automation products, including servo drives. Servo drives play a crucial role in automation and robotics applications where precise control of movement is required. They receive commands from a controller, such as a PLC (Programmable Logic Controller) or a motion controller, and translate these commands into electrical signals that drive the servo motor accordingly. Some models may offer programmable functions and parameters to customize control algorithms and behaviors.
