Embodiment Construction

[0044] Please refer to FIG. 8 . FIG. 8 is a frame diagram of an embodiment of a fieldbus-based micro servo motor control system. As shown in the figure, the system includes: a group of servo motors 81-84; a group of controllers 91-94, one end of each controller is connected to the field bus, and the other end is connected to the corresponding servo motor, and one controller controls one servo motor. It is used to process the control signal from the field bus, and then transmit the control signal suitable for the corresponding servo motor to the corresponding servo motor; and a host computer 100, one end of the host computer 100 is connected to a group of controllers through the field bus 91-94, which is used to transmit control signals to a set of controllers 91-94.

[0045] It should be understood that the present invention is not limited to a set of servo motors, a set of controllers and a host computer. Please refer to FIG. 9 , which is a frame diagram of another embodimen...

Abstract

A method for controlling microservo-motor based on on-site bus includes transmitting control signal to various controllers by up-level computer through on-site bus and then sending control pulse in relevant width to its corresponding servo-motor by each controller after a series operation is done by said controller. The system used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to a micro servo motor control system and method, in particular to a field bus-based micro servo motor control system and method. Background technique [0002] A micro servo motor is a typical position closed-loop feedback system, please refer to Figure 1, which is a schematic diagram of a traditional servo motor. It generally includes the following parts: a small DC motor 11; a set of speed change gears 12; an adjustable potentiometer 13 and a control circuit board 14, and the above components form a circuit in turn. The basic principle of the servo motor is that the DC motor 11 provides the original driving force, decelerates through the speed change gear 12, and at the same time increases the output torque of the DC motor 11, the adjustable potentiometer 13 is used to feed back the current position signal of the servo motor, and the control circuit board 14 according to the control The signal and the feedback signal provided b...
