Designed to perform accurate, high-performance motion control for stepper motors in CompactPCI and PXI systems, PXI-7314 open-loop and PXI-7324 closed-loop controllers are compatible with firm's LabVIEW, BridgeVIEW/CVI and C/C++ software. The stepper modules can control up to four motors with fully programmable pulse and direction or clockwise/counterclockwise output signals, amplifier inhibit/enable signals, and forward, reverse, or home limit inputs per axis. Stepper control includes velocity and acceleration profiling with S-curve acceleration boost for enhanced motion trajectory performance. Step output pulse rates are up to 1 MHz to handle full, half and micro-step applications. The closed-loop version adds quadrature encoder feedback inputs for each axis to allow motion tracking, positioning breakpoints, following error control and in-position verification.
