The invention discloses a synchronous control method and control equipment for a gantry and a motor control system. A first motor driver and a second motor driver are connected by a communication bus,the first motor driver acquires first position information of a first motor driven and controlled by the first motor driver, the second motor driver acquires second position information of a second motor driven and controlled by the second motor driver and sends the second position information to the first motor driver through the communication bus, the first motor driver sends the first and second position information to the control equipment, and the control equipment carries out compensation control of a gantry position according to positions of the first and second position information. Compared with an existing gantry control mode, capacity of resisting disturbance is higher by interacting the position information through the communication bus, and wiring between the second motor driver and the control equipment can be simplified, so that the complex degree of wiring can be reduced to a great extent, the reliability of the system is improved and the using and maintenance costs ofthe system are lowered.
本发明公开了一种龙门同步控制方法、控制设备及电机控制系统,第一电机驱动器与第二电机驱动器通过通讯总线连接,第一电机驱动器获取其驱动控制的第一电机的第一位置信息,第二电机驱动器获取其驱动控制的第二电机的第二位置信息,并通过通讯总线发给第一电机驱动器,第一电机驱动器将该第一位置信息和第二位置信息发给控制设备,控制设备根据该第一位置信息和第二位置信息之间的位置差进行龙门位置补偿控制;相对现有龙门控制方式,通过通讯总线实现位置信息的交互,抗干扰能力更强,且可简化第二电机驱动器与控制设备之间的接线,可在很大程度上降低接线的复杂程度,提升系统的可靠性,降低系统的使用和维护成本。
