precise stepper motion control.
System Connection
The NI 9512 has two connectors, a 15-pin DSUB drive interface
connector and a 20-pin MDR feedback connector. The 15-pin
DSUB incl
u
des command signals for interfacing with stepper
drives, 0 to 30 V general-p
u
rpose digital inp
u
t and o
u
tp
u
t lines, and
a +19 to 30 V inp
u
t for power connection. Refer to Table 1 for the
DSUB connector pin assignments.
The 20-pin MDR connector incl
u
des incremental encoder
feedback inp
u
ts, a +5 V o
u
tp
u
t for encoder power, home, limit, and
position compare inp
u
ts, an o
u
tp
u
t for position compare, an
addi19 to 30 V inp
u
t for power connection, and an
additional 0 to 30 V general-p
u
rpose digital inp

t line. Refer to
Fig
u
re 2 for the MDR connector pin assignments.
Note
The NI 9512 req
