Product Description Module Parameter Core Advantages and Series Overview of M-itsubishi PLC Modules M-itsubishi PLC modules have won wide recognition for their outstanding quality of high durability, wear resistance, and long service life. As genuine original products, they feature reliable and guaranteed quality. They not only have a wide range of applications to meet the needs of various industrial scenarios but also offer diverse options due to their complete product categories. Choosing genuine original M-itsubishi modules ensures longer service life and more trustworthy quality; it is a wise choice to recognize genuine original products and select reliable channels. Its main series include MELSEC iQ-R Series, MELSEC-Q Series, MELSEC-L Series, MELSEC iQ-F Series, MELSEC-F Series, and MELSEC-QS/WS Series, which fully cover the needs of different applications. Reverse-Forward Motor Control Circuit Using M-itsubishi FXSeries PLC The power circuit diagram shown in the figure illustrates a basic reverse forward motor control circuit.The two contactors, KM1 (FWD) and KM2 (REV), are wired to control the changing direction of the motor's rotation. The forward contactor, KM1, is directly wired to the three-phase supply lines (L1, L2 & L3). On the other hand, the reverse contactor, KM2, is wired in a way where two of the phase lines are interchanged, which is necessary for changing the direction of rotation of the motor. Instead of the traditional switching operation of contactors via physical wired components like relays and logic switches, the control circuit is contained within the memory of the PLC. Only the push button switches, thermal overload contact, and auxiliary relays are externally connected to the PLC. CPU Performance Built-in Analog Input and Output High-Speed System Bus The MELSEC iQ-F Series is equipped with a high-speed processing CPU with an instruction operation speed (LD instruction) of up to 34 ns. In addition, it supports the execution of structured programs and multi-programs, as well as ST language, FB, etc. The FX5U is equipped with 2 channels of 12-bit analog input and 1 channel of analog output. While equipped with a high-speed CPU, the MELSEC iQ-F Series also achieves high-speed system bus communication of up to 1.5 Kwords/ms (approximately 150 times faster than the FX3U). Even when using intelligent function modules with a large number of communications, it can maximize its performance. Built-in ETHERNET Port Built-in SD Memory Card Slot Built-in RS-485 Port The ETHERNET communication port supports 8-channel communication on the network, enabling simultaneous connection of computers and related devices. In addition, it supports seamless SLMP communication with upper-level machines, etc. The built-in SD memory card slot greatly facilitates program upgrades and mass production of equipment. In addition, data can be recorded on the SD memory card*1, which is highly helpful for grasping and analyzing equipment status and production conditions. The built-in RS-485 communication port enables communication with Mitsubishi Electric general-purpose inverters at a distance of up to 50 meters, supporting up to 16 units (controllable via 6 inverter-specific commands). In addition, it supports the MODBUS function, allowing connection to 32 stations of PLCs, sensors, temperature controllers, and other devices that support MODBUS.
