OMS Motion Inc. Product
Member Since 2008
OMS Motion, located in Beaverton, Oregon, has been successfully producing motion controllers for more than 35 years. OMS Motion was founded as Oregon Micro Systems (OMS) and evolved from patented motion control technology that provide superior advantages in the industry. OMS built a strong reputation in the market for reliable and quality motion control products backed by superior customer service and technical support. These motion controllers can control 10 axes of motion on a single controller for servo and/or stepper motor control. OMS also produces integrated controller & drive in small compact sizes for deployment near or on the motor. Applications of OMS products include semiconductor and medical equipment, life sciences and factory automation markets, as well as research facilities around the world. In addition to creating multi-axis motion controllers, OMS offers motors, drives and accessories that are often tailor-made to support specific applications.

The MAXv2 VME bus motion controller is an all new core design from the previous MAXv and provides more expanded capability to the overall performance. The MAXv2 offers absolute encoder support on all axes (BiSS or SSI).
The OMS Motion Inc. MAXv2 motion controllers form a family of high performance VME bus-based products and are in compliance with the universal 6U VME/VME64 Bus Specification ISO/IEC 15776 (2001 E). The MAXv2 motion controller can manage up to 8 axes of open-loop stepper, closed-loop stepper or servo systems, in any combination at the user’s option, as incremental or absolute encoder feedback can be provided on each axis. The OMS MAXv2 controller synchronizes all independent or coordinated motion of up to 8 axes, while incorporating other critical signals, such as hard or soft limits, home, and other digital and/or analog I/O signals, to provide the motion solutions to perform virtually any task. With high level functionality, such as additional two encoder inputs, circular and linear interpolation, multi-tasking, custom profiling, backlash compensation, etc., the MAXv2 can satisfy the needs of most any motion control application.
The MAXv2 communicates as a “slave only” device and functions as a motion co-processor to the host on the VME bus. It utilizes 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 MAXv2 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 MAXv2 can provide motion control information such as axis and encoder positions as well as the state of over travel limit inputs, home switch inputs, and done flags. The MAXv2 motion controllers utilize an OMS custom VME and Bridge, enabling an efficient and rapid data transferring between the on-board microcontroller and the VME host.
The stepper control of the MAXv2 produces an average 50% duty cycle square wave step pulse at velocities of 0 to 4,000,000 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 bi-polar +/- 10V or unipolar 0 to +10V. The encoder feedback control can be used as closed-loop feedback for the servo PID, position maintenance for the stepper axes or strictly as a position reference for any axis. The incremental encoder input supports single-ended quadrature TTL signals at a rate of up to 8 MHz and counts at a times 4 resolution. This means a 1000 line encoder will produce 4000 counts per revolution in the MAXv2 controller. The absolute encoder input supports BiSS and SSI formats with up to 40+ bits. The MAXv2 motion controller has 6 general purpose analog inputs that utilize a 16-bit ADC, with a DC range of +/- 10 VDC. Two additional +/- 10 V DACs that are not assigned to any axis are also available.
