DA98E AC servo Drive Unit (also known as bus-oriented AC servo Drive Unit) is anew generation of products with an up-to-date industrial Ethernet bus communication interface.
The external control device for the series of Unit can communicate with several GSK-LINK bus-oriented AC servo Drive Unit through only one network cable. They feature simple interfaces,easy installation and high compatibility. Through a high-speed and reliable GSK-LINK field bus andprotocol, a NC system may receive/send diversified data including position, speed command, motorencoder data, controlling parameters for current loop, speed loop and position loop, state parametersof drive unit and other messages from/to a servo Drive Unit. By supporting diversified data, thesystem may exert control over the operation of a motor and better realize the real-time monitoring ofthe control and drive Unit through configuration of position, speed command and adaptiveparameters of the system, thereby further improving the processing efficiency and accuracy of the NC system. With a built-in advanced and dedicated chip for control over the motor, a FPGA(Field-Programmable Gate Array) and a new IPM intelligent power module, the servo drive unit ischaracterized by high integrity, compactness, complete protection and high reliability.
DA98E AC servo unit has the following advantages over step drive Unit:
The servomotor is provided with an encoder that Open-loop control Stepper motor
feeds back position signal to the servo drive unit
and exerts semi-closed loop control with an
open-loop control device.
Wide speed ratio and constant torque
Speed regulation ratio of 1: 5000 and constant
torque characteristics at low to high speed; Controller
Incremental encoders or Tamagawa 17-bit
absolute encoders are available upon customer’s request.
High speed and accuracy
Maximum rotating speed of servomotor: 3,000 rpm; rotary positioning accuracy: 1/10,000r
Note: The maximum rotating speed of servomotor varies with its model.
DA98E Series AC Servo Drive Unit User Manual
Simple and flexible control
It is possible to properly set the operating mode and characteristics of the servo system through
the system interface in order to meet different requirements.
DA98E compared to the traditional DA98 servo series
The data transfer speed is up to 100MBit/s by using an industrial Ethernet bus for
High anti-jamming capacity, bit error rate: 10-12
The closed and open loops share one hardware structure with a communication data
length of 0～256 (bits) and minimum communication cycle of 50µs.
It is easy to operate and adjust servo parameters and possible to adjust servo parameters
and monitor servo through the system interface.
