A new digital servodrive network that operates at 200Mbit/s has been launched by Motor Technology. Developed for motion control applications by Ormec, ServoWire uses the IEEE-1394 `FireWire’ open standard.
ServoWire provides high speed, real time communication for up to eight servo drives and motors controlled by a single module.
Network bandwidth is allocated to each servo using isochronous transfers that are unique to IEEE-1394, ensuring timely transmission of torque commands, positional feedback and high speed I/O status during each loop update.
