1756-L73 Controller module
1. Enhanced features: For high-performance motion driver control on Ethernet /IP or SERCOS interfaces, supporting up to 100 axes; Faster dual-core custom CPU improves controller scan time; CIP connections increased from 250 to 500; The default value of the unconnected buffer has been increased from 10 to 20(maximum 40); The 1756-L73 provides «Dual Data Rate» (DDR) backplane communication; 1gb removable secure Digital memory card (SDRAM); Energy storage module (ESM).
2. Parameter setting: the external wiring diagram of the device in the mechanical press application, and the fuse, reactor and filter need to be installed in the front end of the armature power supply to protect the DC speed regulation device, stabilize the power grid, reduce electromagnetic interference and other functions. A fuse should also be installed between the DC power output and the motor, which can be fused to protect the DC speed regulating device when the motor side is short circuited.
3. Control function
The control function includes PID control operation, feedforward compensation control operation, ratio control operation, etc., which should be determined according to the control requirements. Programmable logic controller is mainly used for sequential logic control, therefore, most occasions often use a single loop or multi-loop controller to solve the analog control, and sometimes also use intelligent input and output units to complete the required control functions, improve the processing speed of programmable logic controller and save memory capacity. For example, PID control unit, high-speed counter, analog unit with speed compensation, ASC code conversion unit, etc.
