Driver: mr-h ACN series ssc-net compatible AC same service rated output: 0.2KW The same server controller can easily convert the operation module and Fieldbus module through the automation interface At the same time, different fieldbus modules are used to realize different control modes (RS232, RS485, optical fiber, INTERBUS and PROFIBUS), while the control mode of general frequency converter is compared with single-mr-pwcns5. The servo controller is directly connected to the resolver or encoder to form a closed-loop mr-pwcns5 for speed and displacement control, while the general frequency converter can only form an open-loop control system mr-pwcns5 The control indexes of servo controller (such as steady-state accuracy and dynamic performance) are better than general frequency converter. Optical fiber length: 0.5m. Sscneti application cable (standard optical fiber used in the control cabinet). Connector for cn1a and cn1b, Shenji general AC servo amplifier melcervo-j3 series mr-pwcns5, rated output: 5.0kw. Interface type: sscnet optical fiber communication type. Power specification: three-phase AC400V. By using sscnet III high-speed serial communication with the fastest communication cycle of 0.44ms between the motion controller and the servo amplifier, a fully synchronous control system can be constructed. Just insert the special optical fiber into the connector to form the sscnet network, which greatly reduces the wiring work and the possibility of miswiring. Due to the use of optical fiber communication, the anti noise ability is greatly improved, and the original mr-pwcns5 can realize long-distance wiring up to 800m (the maximum 50m x16 axis between stations) Provide servo amplifier mr-j3-b-rj006 meeting the full closed-loop control function. It is suitable for the optimization and adjustment of the same clothes of dry machinery More advanced optimization adjustment function and control function to maximize the mechanical performance. Electric general AC servo amplifier melcervo - J3 series. Rated output: 7.0kw original mr-pwcns5 interface type: sscnet optical fiber communication type. Special specification: full closed loop control type. Power specification: three phase ac200v. High precision and high response positioning control. The full closed-loop control with high response can be realized through double feedback control, The dual feedback control can be performed when switching between the servo motor encoder and the load side encoder. Mr-j3-b-rj006 can be used with linear encoders from many manufacturers. Users can build the original mr-pwcns5 system according to their own accuracy requirements. The ABS linear encoder with serial interface can easily build an absolute position detection system without installing a battery on the servo amplifier.
