Caution
To meet radio frequency emission requirements
for marine applications, use shielded cables and install the
system in a metal enclosure. Suppression ferrites must be
installed on power supply inputs near power entries to
modules and controllers. Power supply and module cables
must be separated on opposite sides of the enclosure and
must enter and exit through opposing enclosure walls.
Connecting the NI 9512
The NI 9512 stepper drive interface module is part of a family of
C Series motion modules. The module provides stepper drive
interface signals for a single axis, a full set of motion I/O including
inputs for a home switch and limit switches, incremental encoder
inputs for position feedback, and 0 to 30 V digital input and output
lines. The NI 9512 also includes a processor to run the spline
interpolation engine and patented NI step generation algorithm.
Working together they produce smoother motion resulting in
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
