Therefore, the physical position of the 485 motor control panel is arranged in the middle of the motors, the physical distance between the 485 motor control panel and the motors can be shortened, and the original complex long wirings between the PLC control cabinet and the motors are optimized into 5 connecting wires between the PLC control cabinet and the 485 motor control panel and a plurality of short wirings between the 485 motor control panel and the motors; meanwhile, the 485 motor control panel only leaves an I/O interface to the motor drive control module on the production line, only limits the read-write function, and cancels the conventional communication function between the original PLC control cabinet and the motor drive control module, so that the connection can be realized only by using a common wire, and the wiring difficulty is greatly reduced.
And in subsequent maintenance, because the 485 motor control panel only leaves the I/O interface to the motor drive control module on the production line, the maintainer very easily judges whether the line fault position is between the PLC switch board and the 485 motor control panel or between the motor drive control module and the 485 motor control panel: if 5 connecting lines are optimized between the PLC control cabinet and the 485 motor control panel, maintenance personnel can determine the maintenance position more easily; if between 485 motor control panels and motor drive control module, then direct change the electric wire of connection can, reduce the maintenance degree of difficulty by a wide margin.
In order to optimize wiring structure, as the utility model discloses an preferred scheme, PLC switch board connects at least two 485 motor control panel, and is a plurality of motor drive control module divides the multiunit, and every 485 motor control panel corresponds with a plurality of motor drive control module with a set of and is connected. A plurality of motors and motor drive control modules in a production workshop are divided into a plurality of groups, and each group of motors and motor drive control modules is uniformly distributed with a 485 motor control panel, so that the 485 motor control panels are closer to the physical positions of the motor drive control modules connected with the 485 motor control panels.
For convenient wiring and later maintenance, as the utility model discloses further preferred scheme, every 485 motor control panel connects two to four motor drive control module.
Compared with the prior art, the utility model, have following advantage:
the utility model discloses many motor control wiring structure utilizes 485 motor control panel as the relay, only use the power cord between PLC switch board and the 485 motor control panel, the ground wire, and three 485 communication lines are five line connections to 485 motor control panel altogether, and set up the intermediate position of 485 motor control panel at a plurality of motors that connect, many long wirings of complicacy between original PLC switch board and a plurality of motors, optimize 5 lines between PLC switch board to 485 motor control panel, and many short-term wiring between 485 motor control panel and a plurality of motors, thereby reduce the wiring degree of difficulty and the subsequent maintenance degree of difficulty.
