About This Product

The LFA7 is a small universal board equipped with the Motionnet center device (G9001A) manufactured by Nippon Pulse Motor Co., Ltd. and a control MCU, and uses three types of serial communication LSIs manufactured by Nippon Pulse Motor Co., Ltd. (I/O local device, local device for pulse control, local device for MCU emulation) Serial communication with up to 64 units and communication speeds of up to 20Mbps allows remote input/output control required in the FA field. In cyclic communication, which performs input/output control for motor control, MCU emulation, and message communication, 4-byte data is always transferred at a maximum of 15.1 μsec, and 256-byte (max) data such as motor control and LSI control data is inserted in between. Can communicate. The communication time can be calculated using a predetermined formula, guaranteeing the real-time performance required in the FA field. LFA7 is a Motionnet compatible product equipped with NPM's G9001A center device with "middle hardware" LFA series specifications. In addition to complying with the series standard specifications, this model is equipped with Renesas Electronics' RX630 (R5F5630) general-purpose CPU, so not only can command specifications be customized, but sequence operations can also be performed independently. Of course, dedicated software has been implemented so that it can be used with simple commands, so you can use it without any knowledge of Motionnet. Since it is isolated from the internal circuitry by a pulse transformer, it can be safely connected to various Motionnet local device products.

■What is Motionnet?

・Motionnet is a high-speed 20Mbps serial communication system developed by NPM that emphasizes real-time performance.It is a total wiring-saving system that supports not only input/output control and motor control required in the FA field, but also CPU emulation and message communication. - Recognized as the network communication standard SEMI E54.21 of the international standard planning SEMI standard, and can be used with confidence as the global standard for internal networks.
