Drive Command Output
The NI 9514 module provides a ±10 V analog Drive Command
output. Use the Drive Command COM signal instead of COM as a
reference for the Drive Command Output. This reference signal
helps keep digital noise separate from the analog output.
Encoder Signals
The encoder channel consists of a Phase A, a Phase B, and an Index
input. The NI 9514 supports RS-422 differential and single-ended
inputs for Phase A, Phase B, and Index signals, and provides a
+5 V output for encoder power. National Instruments strongly
recommends you use encoders with differential line driver outputs
for optimized noise immunity and improved accuracy in all
applications. Figures 5 and 6 show simplified schematic diagrams
of the encoder input circuit connected to differential and
single-ended encoder outputs.
