Problems solved by technology
The controller adjusts the control amount according to the difference between the given value of the numerical control system and the actual operating value detected by the feedback device; in a common system, one servo system usually controls one servo motor, and when there are multiple In the case of servo motors, since these servo motors are controlled separately, it is impossible to uniformly deploy these servo motors, so that multiple servo motors can operate more optimally as a whole

Embodiment Construction
[0022] The present invention will be described in further detail below in combination with specific embodiments.
[0023] This embodiment provides a motor servo system, such as figure 1 As shown, it includes a plurality of local control modules 1 and an upper controller 2, and the plurality of local control modules 1 are connected to the upper controller 2, wherein:
[0024] Described local control module 1 comprises servomotor 12, output signal feedback device 11, local controller 13; Servomotor 12 is connected to output signal feedback device 11, and output signal feedback device 11 is connected to local controller 13, and local controller 13 is connected To the servo motor 12, the local controller 12 is connected to the upper controller 2;
[0025] The output signal feedback device 11 sends the servo motor running state information fed back by the servo motor 12 to the local controller 13;
[0026] The local controller 13 receives the servo motor running state information...

The motor servo system proposed by the present invention includes a plurality of local control modules and a host controller, wherein each local control module will monitor the running state of the servo motor in real time, and will stop the operation of the servo motor immediately when it detects that the servo motor fails. In this way, some serious faults will be dealt with immediately, which reduces the reaction time, thus ensuring the safe and normal operation of the servo motor. The host controller will receive the running state information of the servo motor sent by multiple local control modules, and will comprehensively analyze and process it, and then send corresponding control instructions to each local control module. Since the host controller can receive the operating status information of multiple servo motors, it can perform comprehensive deployment based on the information, so that multiple servo motors can work better with each other.
Description
technical field [0001] The invention relates to a motor servo system, which belongs to the field of motor control. Background technique [0002] The servo system can accurately track the reference signal process, and it is widely used in the fields of CNC machine tools, wind power generation, industrial machinery and so on. The servo system is mainly composed of three parts: controller, power drive device, feedback device and servo motor. The controller adjusts the control amount according to the difference between the given value of the numerical control system and the actual operating value detected by the feedback device; in a common system, one servo system usually controls one servo motor, and when there are multiple In the case of servo motors, since these servo motors are controlled separately, it is impossible to uniformly deploy these servo motors, so that multiple servo motors can operate more optimally as a whole. Contents of the invention [0003] In order to...
