【功能描述】
1756-L73控制器模块
参数设置：该装置在机械压力机应用中的外部接线图,另外需在电枢电源前端加装熔断器、
电抗器及滤波器,以起到保护直流调速装置、稳定电网、减少电磁干扰等作用,.直流电源输出和
电机之间也要加装熔断器,电机一侧短路时可以熔断以保护直流调速装置。
控制功能
控制功能包括PID控制运算、前馈补偿控制运算、比值控制运算等,应根据控制要求确定。
可编程逻辑控制器主要用于顺序逻辑控制,因此,大多数场合常采用单回路或多回路控制器解
决模拟量的控制,有时也采用的智能输入输出单元完成所需的控制功能,提高可编程逻辑控制器
的处理速度和节省存储器容量。例如采用PID控制单元、高速计数器、带速度补偿的模拟单元、ASC码转换单元等。

【英文介绍】
1756-L73 Controller module
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.
2. 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.
