NI PXI-7340

NI identifies the NI 7340 as a combination servo and stepper motor controller, and the user manual explicitly covers the NI PXI-7340 or PCI-7340 motion controller. The PXI-7340 is therefore a primary controller module rather than an accessory, and NI states that the 7340 motion controller provides motion control for up to four independent or coordinated axes.

For motion functions, NI specifies ±10 V analog command outputs for servo operation. For stepper control, the controller supports step/direction or CW/CCW outputs with a maximum pulse rate of 4 MHz and output voltage of 0 to 5 V. NI also specifies quadrature, incremental, single-ended encoder inputs with a 20 MHz maximum count rate, plus dedicated per-axis motion I/O including limit and home inputs, breakpoint outputs, trigger inputs, and encoder feedback.

The PXI-7340 also integrates onboard processing and general-purpose I/O resources. NI specifies a 32-bit CPU, DSP, and custom FPGAs, with onboard execution of up to 10 simultaneous motion programs. The hardware includes 32 bits of digital I/O, four user analog inputs within a bank of eight multiplexed single-ended analog inputs, four single-ended analog outputs rated at ±10 V and 16-bit resolution, and two PWM outputs up to 50 kHz with 8-bit resolution.
