Operation Theorem
•
55
Step 0: All Register and Pre-Register is empty.
Step 1: The first motion is executed and CPU writes corresponding values
into pre-register 2.
_7443_start_ta_move(0,50000.0,100.0,30000.0,0.1,0.0)
Step 2: Since Pre-register1 & Register is empty, the data in pre-register 2 is
moved to Register automatically and executed instantly by ASIC.
Step 3: Then second function is called. CPU writes the corresponding
values into pre-register2.
_7443_start_tr_move(0,20000.0,100.0,30000.0,0.0,0.2)
Step 4: Since Pre-register1 is empty; the data in pre-register 2 is moved to
Pre-register1 automatically and wait to be executed.
Step 5: Now user can execute 3
rd
function, and it will be stored in Pre-
register2
Step 6: When the first function finished, the Register becomes empty, and
data in pre-register1 is allowed to move to register then executed instantly
by ASIC, and, data in pre-register2 is moved to pre-register1.
Step 7: The ASIC will inform CPU by interrupt that motion is completed. And
user can write 4
th
motion into Pre-Register 2.
Procedures to perform continuous motion
The following procedures are to help user making continuous motion.
Step 1:
(if Under Dos)
Enable the interrupt service by _ 7443_int_contol()
(if Under Windows)
Enable the interrupt service by _ 7443_int_contol() and
_ 7443_int_enable().
Step 2: Set bit “2” of INT factor to be “True” by _ 7443_set_int_factor()
Step 3: Set the “conti_logic” to be “1” by: _ 7443_set_continuous_move()
(note: if all motions are of relative mode, this function could be
ignored. )
Step 4: Call the first three motion functions.
Step 5: Wait for INT(under DOS) or EVENT(under Windows) of pre-register
empty.
