I-8091 2-axis Stepping/Servo Motor Control Card
The I-8091 card is a 2-axis command-type stepping motor control card
on I-8000 platform, it also can be used as servo motor control (pulse input
type). This card has an embedded CPU which performs motion commands
transfered from I-8000 main system to increase the system performance. A
2Kbytes-FIFO is introduced as command buffer. This buffer can provide over
700ms buffer time.
A system including I-8000(main system), I-8091(2-axis stepping/servo
control card), I-8090(3-axis encoder card) can be implemented as a stand
along motion controller system for low cost automatical machine.
