    Servo Drive Troubleshooting

    Servo driver is a kind of controller used to control the servo motor, which belongs to the servo system. When some problems accur as follow of a servo drive, how we should test and repair? Here are 6 tipsĀ  to maintain a servo drive.

    What Communication type is used for Servo Motor & Drive System?

    Sometimes one has to (still) use a dedicated net just for servos but that is old. Different fieldbuses and/or servo drive interfaces may support a partial frame; for example, one may only be able to set a control word which might be position or torque command while some may support a full parameter frame or command set which exposes a plethora of servo parameters and variations between the two extremes. Speed is also a consideration i.e. may only be fast enough to do motion control or fast enough to close a servo torque loops and/or fast enough to incorporate feedback devices e.g. force or range sensors (without wiring directly to the servo drive).

    Servo Drive Basics & Working Principle

    The servo drive is a kind of controller to control the servo system. Its function is similar to the frequency effect on ordinary AC motor, which belongs to a part of the servo system and is mainly applied in high-accuracy positioning system. Generally, the servo motor is controlled by three ways, location, speed and torque, so as to realize high precision positioning of transmission system.

    Servo System Classification and Function

    Nowadays, with the continuous development of technology, AC servo motor technology gradually replaced the DC motor as the leading executive motor with its excellent cost performance. The mature technology of AC servo system also makes the market develop rapidly and become one of the supporting technologies of industrial automation. So what are the main functions of servo system and how is it classified? Continue and you will learn about that.

    AC Servo Driver for Industrial Sewing Machine

    Industrial sewing machine control system is a comprehensive and strong technology, which involves many aspects of knowledge, such as the principles of mechanical and electrical equipment, operation technology and so on. As the core running component in industrial sewing machine, the servo system plays a key function in running of this equipment.
    This control system mainly includes special controller, AC servo system and stepper motor system, in which the controller mainly consists of main control board and two step drive boards. So it can directly sends pulse to control stepper motors in axis-X and axis-Y, while the needle is controlled by servo motor through needle bar directly connected with coupling.

    Servo System Controlling in CNC Bending Machine

    CNC Bending Machine is a machine to process metal plates and it mainly uses hydraulic system to blend panels into different shapes. In view of defects of the hydraulic system of traditional bending machine and characteristics of forming techniques and processes of equipment, it adopts servo drive, servo motor, and gear pump to adjust control system of flow and pressure of hydraulic system, which can reduce system energy consumption and temperature-rising of hydraulic oil, and improve operational reliability of equipment at the same time.

    Energy Saving Servo System for Injection Molding Machine

    Illustrate the transformation process by taking dedicated servo system of injection molding machine: First, it should replace general asynchronous machine and dosing oil pump of the former system with servo motor and internal gear pump, add pressure transmitter in output direct pipes of oil pump and get rid of proportional pressure valve of the former system and corresponding amplifier board. Pick up analog signals whose pressure and flow are given from computer control of injection molding machine, transform them into 0-10V DC analog pressure signals through comprehensive processing and directly add them in input terminals of system pressure given signals and system flow given signals of servo drives, and connect pressure sensors in exit of oil pump with pressure feedback signal terminal of servo. Servo system can have PI adjustment through connected pressure and flow signals and change output torque and speed of servo motor so as to change output flow Qt and pressure p of oil pump to meet oil pressure and flow required by injection molding machine in various processes.
