Highest Controlling Speed: 4MPPS
The motion control boards control the speed of drive-pulse output from 1PPS to 4MPPS with a stable trapezoidal drive. The velocity accuracy is controlled within ±0.1% when the speed is from 1 to 8 KPPS. Different drive speeds can be set, and altered in a designated drive command.

Simple Drive Commands
Two drive commands, index drive and continuous drive, can be used to perform the drive-pulse output. The speed acceleration / deceleration will happen if the setting drive speed is higher than the initial speed; the speed will be constant if the setting drive speed is lower than the initial speed. The drive-pulse output speed (PPS) is decided by the setting drive speed setting range.

Two 24-bit Position-Managing Counters
Two 24-bit up/down counters are equipped for each axis: the logical position counter for pulse output and the real position counter for pulse feedback. The circuit for pulse feedback, with a high-speed photo coupler, can be connected with an A/B quadrature encoder of line-drive output system.

Functions of Compare Register and Software Over-Travel Limit
For each axis, three compare registers with numeral values are equipped to compare the position counts. During the driving, these registers are a convenience for the in-position measurement or for the machine works handling. Two of these three compare registers are equipped with + or - side software over-travel limit.

Line-Driver and Drive-Pulse Output
Line-driver 26LS31 is adopted for drive-pulse output. Photo coupler or other line-drivers are possible to be connected.
