Nippon Pulse introduces Serial Communication System

May 12, 2010 By Motion Control Tips Editor Leave a Comment

Nippon Pulse (www.nipponpulse.com) unveiled its latest serial communication networking system, the Motionnet system. It allows operators to greatly reduce wiring and it provides message communication, CPU emulation, motor control and input/output control. The new network system can transfer four bytes of data in 15.1 µsec with cyclical communication to control both output and input. The Motionnet system is ideal for semiconductor equipment, factory automation and biomedical machines. It can construct a multi-axis communication system to reduce wiring costs.

The G9001A chip can control up to 64 local devices and is the system’s center device, G9001A has 256 bytes of RAM for I/O control and it has 512 bytes of RAM for data. It can also support a maximum 256 bytes of data communication in a local data device. With a 64-pin QFP, the G9001A device features a 20Mbps maximum communication speed.

The G9003 and G9002 chips are local devices, which can be connected into the G9001A center device. Operators are able to connect of up to 64 devices to each chip or 64 combined devices to both chips (“no more than 64”).

The G9002 chip is categorized as I/O device. The 80-pin QFP, the chip has four 8-bit ports per device, features a tolerant buffer, and it makes use of cyclic transfer. While the G9003 is the motor control device, which can control a stepper motor or single axis servo based in instructions from center device with a 6.5Mpps maximum output. Operators can get encoder signal interface, various motion profiles and the ability to change speed and position on the fly.

With CPU emulation device, G9004A chip, which can be utilized in either message communication mode or CPU emulation mode and exchanges data with center device. The G9004A can communicate a maximum 256 bytes (“per burst”) and features both 16-bit and 8-bit CPU interfaces.
