1. Motion manipulator
The use of motion control in the field of robotics and CNC machines is more chaotic than in specialized machines, which are more sketchy and often referred to as General Motion Control (GMC).
2.plc
Programmable logic manipulators are digital manipulation electronics designed for use in industrial environments. It uses a programmable memory to store instructions for performing operations such as logic operations, sequence control, timing, counting, and arithmetic operations, and uses digital or analog inputs and outputs to control various types of mechanical equipment or production processes.
3. The difference between the motion controller and the PLC
The motion control mainly touches the control of stepper motors and servo motors, and the control structure mode is generally: control equipment + driver + (stepper or servo) motor.
The control equipment can be a PLC system, or a special automation equipment (such as motion controllers, motion control cards). When the PLC system is used as a control equipment, although it has the flexibility and versatility of the PLC system, it is difficult to achieve or programming when the requirements of high precision, such as interpolation control, are sensitive to the requirements, and the cost may be high.
With the progress of technology and the accumulation of technology, the motion controller came into being, which solidifies some universal and special motion control functions in the middle - such as interpolation instructions, users only need to configure and call these function blocks or instructions, which reduces the difficulty of programming, and also has advantages in terms of performance and cost.
It can also be understood in this way: the use of PLC is a general motion control equipment. A motion controller is a special type of PLC that is used exclusively for motion control.
