Introduction
EMP2-3B applied in the MPCL 1000B ASIC developed by this institute, send the movement of each axis
Evenly by DDA(Digital Differential Analyzer)method, realized simultaneous motion control of 2 axes
and allows parallel connection of multiple boards operation. The closed loop control adopted P-control law
(the position command can be feed forwarded for compensation), drive the velocity type servo driver by
signal of-10V to 10V, there is an additional encoder feedback function for break wire detection, reduce the
hazard of system invalid. During pulse control, send the driver with CW/CCW pulse.
There are 2 index inputs with latch and interruption function, and 2 general inputs with interruption function.
