【功能描述】
1756-L73控制器模塊
參數(shù)設(shè)置：該裝置在機(jī)械壓力機(jī)應(yīng)用中的外部接線圖,另外需在電樞電源前端加裝熔斷器、
電抗器及濾波器,以起到保護(hù)直流調(diào)速裝置、穩(wěn)定電網(wǎng)、減少電磁干擾等作用,.直流電源輸出和
電機(jī)之間也要加裝熔斷器,電機(jī)一側(cè)短路時(shí)可以熔斷以保護(hù)直流調(diào)速裝置。
控制功能
控制功能包括PID控制運(yùn)算、前饋補(bǔ)償控制運(yùn)算、比值控制運(yùn)算等,應(yīng)根據(jù)控制要求確定。
可編程邏輯控制器主要用于順序邏輯控制,因此,大多數(shù)場合常采用單回路或多回路控制器解
決模擬量的控制,有時(shí)也采用的智能輸入輸出單元完成所需的控制功能,提高可編程邏輯控制器
的處理速度和節(jié)省存儲(chǔ)器容量。例如采用PID控制單元、高速計(jì)數(shù)器、帶速度補(bǔ)償?shù)哪M單元、ASC碼轉(zhuǎn)換單元等。

【英文介紹】
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.
