Product Description: PPC380AE01 HIEE300885R0001 ABB control card realizes multiple servo motors
Multi-axis coordinated control
Motion control card is based on PC bus, using high-performance microprocessor (such as DSP) and large-scale programmable devices to realize multi-axis coordinated control of multiple servo motors
Machine motion control card, including pulse output, pulse counting, digital input digital output, D/A output and other functions, it can emit continuous, high frequency pulse string, over change the pulse emitted
Frequency to control the speed of the motor, change the number of pulses emitted to control the position of the motor, its pulse output mode includes pulse/direction, pulse/pulse mode. Pulse counting can be used for encoder position
Feedback to provide accurate machine position and correct errors during transmission. Digital input/output points can be used for limits, origin switches, etc. The functions include S-type, T-type acceleration, linear interpolation and arc
Interpolation, multi-axis linkage function, etc. The products are widely used in the field of automation control in I industry, which requires precise positioning, fixed length position control system and PC-based NC control system. Specifically, the movement will be realized
The underlying software and hardware of the control are integrated together, enabling the speed and position control functions required by the servo motor control. - A motion control system
The motion control card is the core module of the control system, and it is also the most closely coupled with the design purpose of the control system, once the motion control card is selected, other designs must be selected around the motion control
So how to choose the motion control card is very important to the design of the motion control system.
1, motion control card working principle
Motion control card is a motor motion control card based on bus. The special control chip is used as the core device, the input and output signals are photoelectric isolated, and can be connected with various types of stepper motor drivers
Stepper motor, composed of high-precision position control system or speed regulation system. It can be combined with the computer to form a master-slave control structure: the computer is responsible for the man-machine interface management and other management work; And the motion control card is responsible
All the details of motion control. Through the dynamic link library provided by the manufacturer, the motion control card users can easily and quickly develop the motion control functions they need.
2, the use of motion control card advantage analysis
As an upper control unit based on PC, motion control card has greater flexibility and openness in the development process of special aircraft system. Enables users to develop powerful movements in a short period of time
The control system. Because of the above characteristics, professional motion control card is only widely used in the machine tool industry, and it is also widely used in many small brick machine systems. Linked library
(DLL), users can quickly develop their own motion control system under Windows system conditions. And for the multi-tasking mechanism of Win, the motion control card uses a quasi-device driver
(VXD) technology solves the real-time problem of the control system under the condition of Win. When the program is initialized, the declaration module (MPC01. BAS), will move in the form of a header file
After the state link library is linked, the user can call the motion control function of the board as if calling the Windows internal function.
3. Suppliers
Motion control card companies have the United States GALIL, PAMAC, the United Kingdom's Terio, Taiwan's Delta, Linghua, Advantech. In recent years, the rapid development in China is due to the reasonable performance and openness of the system
The lower price is especially suitable for the Chinese market. In the Pc-based controller field, the factory has gradually emerged, leading manufacturers are Gu high-tech, Lei sai intelligent Zhongwei Xing, Chengdu Lechuang, Shanghai
Dimensional macro, etc., these manufacturers also provide dedicated controllers for some industry segments. Solid high-tech in this segment has a dominant advantage domestic card Shenzhen Solid high should be the strongest. Especially in the country of interpolation Inside is doing the best.
4. Application field
Motion control cards are widely used in various fields that need to control motor motion, including optical adjustment frame, optical translation table, optical rotation table, control, theodolite, coating machine, dispensing machine, handicrafts.
Painting machine, winding machine, clamping machine, oil injection machine, film pressing machine, digital microscope, welding machine, sponge cutting, glass cutting, steel plate cutting, biochemical instrument screw machine, stone engraving machine, laser engraving Engraving machine, fabric cutting machine, foam processing machine, grinder, textile machinery, car washing machine woodworking machinery, vending machine, non-standard automation, non-standard assembly line and so on need motion control fields
