Python Language Implements the Block Motion Action Control of Panasonic Servo Motors

To address the issue that the Panasonic servo motor's Block Motion operation heavily relies on the PANATREM software, a control strategy based on Python language and Modbus-RTU communication protocol is proposed for directly controlling the servo motor Block Motion by a computer. According to the Modbus-RTU communication protocol specification, using object-oriented programming methods and serial communication technology, a complete servo driver parameter configuration and motion control framework is constructed. The focus is on researching the software architecture of the control system, the command timing coordination mechanism, and the complex motion sequence arrangement algorithm. Experimental results show that the constructed system successfully achieved precise parameter reading and writing, status monitoring, and various motion control functions including point position movement and speed mode switching for the specified type of servo driver. This system demonstrates the feasibility of implementing high-performance servo control using a general-purpose computer and standard communication protocols. The proposed method achieves precise control of the Panasonic servo motor's Block Motion action, improving its automation control level.
