Abstract

The present invention discloses a networked multi-axis motor synchronization control device and method. The device comprises a pulse collection module, a controller module, a synchronization serial difference bus, a multi-axis module, a servo motor drive module and a man-machine interaction module. The method comprises: the pulse collection module collects pulse signals outputted by a host command motor, the pulse signals are subjected to optoelectronic isolation processing and then are sent to the controller module, the controller module performs periodic sampling count of the received pulse signals, the pulse count is sent to the multi-axis module through the synchronization serial difference bus, and the multi-axis generates PWM control signals through the current data frame and the feedback pulse signals of a slave motor. The networked multi-axis motor synchronization control device and method is simple in structure and can realize the high-precision synchronization control of the multi-motor through the network and the remote monitoring of the field data.

Description

technical field [0001] The invention belongs to the technical field of motor synchronization, and more specifically relates to a networked multi-axis motor synchronization control device and method. Background technique [0002] The industrial control system is gradually transitioning from a continuous control system to a discrete control system; the discrete control system can perform accurate and fast calculations, and its versatility is better than that of the continuous control system, and it is easy to use and easy to modify. In order to ensure the synchronism of the motor, the existing motor synchronous control technology mostly adopts local control, and the relevant information processing and display of the control system are carried out on site, which cannot meet the requirements of remote monitoring and control of site information by the management team through the network; and in In the synchronous control of the motor, only the high-precision synchronization betwe...
