GF225100 is a DC motor output and speed control of the industry-grade application programmable logic controller. It applies to driving and control of ball screw, gearing and synchronous belt used in all kinds of drives, such as numerical control machine tool and automotive industry. This product is more reliable, easier to use and lower cost than traditional AC servo drive system. GF225100 application field and working principle are briefly introduced as follows.

Application Field

GF225100 is widely used in the automation control of machinery and equipment for and automotive industry. It can drive and control all kinds of drives, such as ball screw, gearing and synchronous belt drives. GF225100 is suitable for the following products:

• HC11 series motor: Linear motor, Glue motor, Spindle motor, Position Motor, Positioning Motor, etc.
• GF2121A series motor: Synchronous motor, Synchronous belt motor, Synchronous belt drive, etc.
• WT0900B series motor: Ball screw motor, Ball screw drive, etc.
• GF2200S series motor: Spindle motor
• GF2500S series motor: Position motor, Positioning motor

Working Principle

GF225100 is based on PLC technology to build the whole system. It can ensure that the motor and the control system can achieve more accurate control, higher speed and higher reliability. The working principle of GF225100 consists of four main modules, namely, user interface, operation and control module, power module and feedback module.

User Interface

The user interface consists of a digital display panel, a status indicator, and an external input selector. The digital display panel is used to show various status information, such as speed, RPM, and cycle time. The status indicator is used to display various warning messages, such as the motor over heat, overload, over current and short circuit. The external input selector is used to select the program series and allocated power output.

Operation and Control Module

The operation and control module consists of a programmable PLC, a digital-to-analog converter, and a stepper motor control module. The PLC controls the whole system through the generated control signals, while the digital-to-analog converter is used to convert digital signals to analog signals for stepper motor control. The stepper motor control module is used to drive the motor in order to achieve accurate control.

Power Module

The power module supplies power to the motor and it is composed of a power supply, power control module and a rectifier. The power supply provides regulated DC power to the motor, while the power control module modulates the power supply output in order to control the speed of the motor. The rectifier consists of a single-phase rectifier, a three-phase rectifier, an AC excitation bridge and a phase lock loop.

Feedback Module

The feedback module is the most important part of the motor drive system and it is used to detect the speed and position of the motor. The feedback module consists of a resolver, a quadrature transducer, and a feedback processor. The resolver and the quadrature transducer are used to detect the position and speed of the motor and generate the corresponding feedback signals. The feedback processor then processes the feedback signals and sends the information back to the PLC, which then adjusts the motor accordingly.

In conclusion, GF225100 is a versatile, cost effective DC drive solution for precise motion control. The PLC-based operation and feedback system ensures higher speed and reliability while the digital-to-analog converter enables accurate control of stepper motor. It offers an efficient and reliable way to achieve reliable control of motion-related applications in the automotive industry.
