Chips offer serial communications.
Press Release Summary:
Known as center device, Model G9001 has 256 bytes of RAM available for I/O and 512 bytes of RAM for motion control and data communication. I/O Models G9002 and G9003 serve as local devices that can be connected to G9001. Model G9002 has four 8-bit ports, and single-axis Model G9003 outputs 5 Mpps to control stepper or servomotors. CPU emulation device, Model G9004 can operate in CPU emulation mode or message communication mode. It has 8- and 16-bit CPU interfaces.Original Press Release:
New Motionnet Series Offers Serial Communication Capability
Nippon Pulse America, Inc., Radford, VA - (April 22, 2004) Nippon Pulse introduces Motionnet Chips. Motionnet chips, the G900x series, provide the capability of serial communications. Motionnet consists of four chips, the G9001, G9002, G9003, and G9004.
The G9001 is known as the center device. It has 256-bytes of RAM available for I/O and 512-bytes of RAM for motion control and data communication. The G9001 can control up to a maximum of 64 local devices. The maximum communication speed of the G9001 is 20Mbps, and it uses RS485 communication. The G9001 is a 64-pin QFP. The single piece price for the G9001 is $13.74.
The G9002 and G9003 serve as the local devices you can connect to the G9001. You can connect up to 64 pieces of the G9002 (I/O device), 64 pieces of the G9003 (motion device), or any combination of the two (not to exceed 64 pieces total). The G9002 is an I/O device that has four 8-bit ports per device, is an 80-pin QFP, and uses cyclic transfer. The G9003 is a single axis motion device that outputs 5Mpps to control stepper or servomotors. The G9003 offers various motion profiles, an encoder signal interface, and the ability to change speed and position on the fly. The G9003 is an 80-pin QFP. The single piece price for the G9002 is $10.17. The single piece price for the G9003 is $18.41.
The G9004 is a CPU emulation device that can operate in either CPU emulation mode or message communication mode. When in CPU emulation mode, the G9004 outputs signals identical to those from CPU terminals and uses data from the G9001. In message communication mode, the G9004 communicates freely with any CPU connected to the G9001 and itself. The G9004 can control various types of CPU, communicate in 256 byte (maximum) groups, and has both 8-bit and 16-bit CPU interfaces. The G9004 is an 80-pin QFP. The single piece price for the G9004 is $13.74.
Ideal applications for the Motionnet Series would be factory automation, biomedical machines, and semiconductor equipment.
Nippon Pulse America, Inc. is the wholly owned American subsidiary of Nippon Pulse Motor Co., Ltd. Nippon Pulse offers various controllers (boards and chips), drivers (boards and chips), and motors (tin-can and hybrid) to cover almost any stepper motor application.
