PCIx-002 OMS Motion Intelligent Motion Controller Card

The OMS Motion PCIx Series Intelligent Motion Controller Cards can manage up to four axes of stepper or servo motion control while incorporating other signals; i.e. limits, sensors, I/O, etc. into the system. It can manage coordinated or independent motion of each or all of the axes simultaneously. With high level functionality, such as circular and linear interpolation, multitasking, custom profiling, etc., the PCIx can satisfy most any motion control application

The PCIx communicates as a slave only device and functions as a motion coprocessor. It utilizes a 32-bit microprocessor and patented, proprietary technology to control the trajectory profile, acceleration, velocity, deceleration and direction of selected axes. In response to commands from the host computer, the PCIx controller will calculate the optimum velocity profile to reach the desired destination in the minimum time while conforming to the programmed acceleration and velocity parameters. In addition the PCIx can provide motion control information such as axis position, the state of overtravel limits and Done interrupts.

The stepper control of the PCIx produces a 50% duty cycle square wave step pulse at velocities of 0 to 1,044,000 pulses per second and an acceleration of 0 to 8,000,000 pulses per second, per second. The servo control utilizes a 16-bit DAC and outputs either +/- 10V or 0 to +10V. The encoder feedback control can be used as feedback for the servo PID, position maintenance for the stepper axes or as strictly a position feedback of any axes. The encoder input supports either differential or single ended quadrature TTL signals at a rate of up to 4MHz and counts at a 4 times resolution. This means a 1000 line encoder will produce 4000 counts per revolution in the PCIx controller.
