D+P controller Germany D+P model D+P price

D+P controller is a type of controller used to control servo motors. Its function is similar to that of a variable frequency drive acting on a standard AC motor. It is part of the servo system and is mainly applied in high-precision positioning systems. Servo motors are generally controlled via position, speed, and torque modes to achieve high-precision positioning of the transmission system, making it a high-end product in transmission technology. Servo drives are an important component of modern motion control and are widely used in automated equipment such as industrial robots and CNC machining centers. Servo drives applied to control AC permanent magnet synchronous motors have become a research hotspot both domestically and internationally. Current AC servo drive designs commonly adopt current, speed, and position 3 closed-loop control algorithms based on vector control. In this algorithm, the rationality of the speed closed-loop design plays a key role in the performance of the entire servo control system, particularly in speed control performance.

D+P controller introduction

Motion control typically converts predetermined control schemes and planning instructions into desired mechanical motion under complex conditions, achieving precise control of position, speed, acceleration, torque, or force. Depending on the power source used, motion control is mainly divided into electrical motion control using electric motors as the power source, pneumatic and hydraulic control using gas and fluids as the power source, and thermal engine motion control using fuels (coal, oil, etc.) as the power source. According to statistical data, more than 90% of all power sources come from electric motors. Electric motors play a very important role in modern production and daily life; therefore, among these types of motion control, electrical motion control is the most widely used. Electrical motion control evolved from electric traction; electric traction or electrical drive is a general term for control systems targeting electric motors. Motion control systems vary, but in terms of basic structure, the hardware of a typical modern motion control system mainly consists of a host computer, motion controller, power drive unit, motor, actuator, and sensor feedback detection device. The motion controller refers to a control device with a central logic control unit as the core, sensors as signal sensing elements, and motors or power devices and actuators as control objects. [A motion controller is a dedicated controller for managing the operation mode of an electric motor: for example, controlling an AC contactor via a limit switch to move an object upward to a specified position and then downward, or using a time relay to control the forward and reverse rotation of the motor, or intermittent rotation. Motion control applications in robotics and CNC machine tools are more complex than in specialized machines, as the latter have simpler motion forms, often referred to as general motion control (GMC). The motion controller is the main component determining the performance of an automatic control system. For the Mitsubishi series, the motion CPU is the motion controller. For simple motion control systems, a motion controller designed with a microcontroller can meet requirements and offers a high cost-performance ratio.]

D+P controller principle

Currently, mainstream servo drives use a digital signal processor (DSP) as the control core, enabling relatively complex control algorithms and achieving digitization, networking, and intelligence. Power devices commonly use drive circuits designed around intelligent power modules (IPM). IPM integrates drive circuits internally and includes fault detection and protection circuits for overvoltage, overcurrent, overheating, and undervoltage. A soft-start circuit is also added to the main circuit to reduce impact on the drive during startup. The power drive unit first rectifies the input three-phase power or mains electricity using a three-phase full-bridge rectifier circuit to obtain the corresponding DC power. The rectified three-phase power or mains electricity is then converted by a three-phase sinusoidal PWM voltage-source inverter to drive the three-phase permanent magnet synchronous AC servo motor. The entire process of the power drive unit can be simply described as the AC-DC-AC process. The main topology of the rectifier unit (AC-DC) is a three-phase uncontrolled full-bridge rectifier circuit. With the large-scale application of servo systems, the use, debugging, and maintenance of servo drives have become important technical topics. More industrial control technical service providers are conducting in-depth technical research on servo drives. Servo drives are an important component of modern motion control and are widely used in automated equipment such as industrial robots and CNC machining centers. Servo drives applied to control AC permanent magnet synchronous motors have become a research hotspot both domestically and internationally. Current AC servo drive designs commonly adopt current, speed, and position 3 closed-loop control algorithms based on vector control. In this algorithm, the rationality of the speed closed-loop design plays a key role in the performance of the entire servo control system, particularly in speed control performance.

D+P controller features and applications

Servo drives are widely used in injection molding machines, textile machinery, packaging machinery, CNC machine tools, and other fields. Servo controllers can easily switch between operation modules and fieldbus modules via automation interfaces. Different control modes can be achieved using different fieldbus modules (RS232, RS485, fiber optic, InterBus, ProfiBus), whereas general variable frequency drives have relatively single control methods. Servo controllers directly connect to resolvers or encoders to form speed and displacement closed-loop controls. General variable frequency drives can only form open-loop control systems. The various control indicators of servo controllers (such as steady-state accuracy and dynamic performance) are superior to those of general variable frequency drives.
