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. | |
