Title
(EN) Motor control unit with redundancy control
(ZH) 一种带有冗余控制的电机控制单元
Abstract
(EN) The utility model discloses a motor control unit with redundancy control, comprising a power supply module which is connected with commercial power and outputs a corresponding VDC DC power supply forpower supply; one motor control module controls one motor body; the I/O module is used for carrying out signal transmission between the client main control board or the peripheral equipment and the motor control module; the redundancy control module has the function of automatically starting one standby function module when the function modules fail, so that the client system can still work smoothly; the standby function module has the same function as the first function module or the second function module or the third function module; the above functional modules are combined and installed to form the motor control unit, the production mode is flexible and convenient, the adaptability is strong, the research and development period can be shortened, the production is fast and convenient,the operation reliability is higher, the after-sale maintenance is convenient, and the maintenance cost is reduced.
(ZH) 本实用新型公开了带有冗余控制的电机控制单元,包括电源模块,接入市电,输出对应的VDC直流电源供电;电机控制模块,一个电机控制模块控制一台电机机身;I/O模块,用于在客户主控板或者外围设备与电机控制模块之间进行信号传送;冗余控制模块,其功能是在上述功能模块失效时,自动启动一个备用功能模块,从而保证客户端系统仍然可以顺利工作;备用功能模块,与第一功能模块或者第二功能模块或者第三功能模块具有同样功能的模块;将以上功能模块组合安装起来形成电机控制单元,它生产方式灵活方便,适应性强,可以缩短研发周期,生产快捷方便,运行可靠性更加高,便于售后维修,降低维修成本。
