Multi-axis motion control card
VME/VME64, 16 MHz | MAXv Series Pro-Dex, Oregon Micro Systems

The MAXv is a VME/VME64 8-axis motion controller for stepper and/or motor control. The MAXv supports connections on both the VME/VME64 bus P2 connector as well as connectors on the front panel. Each axis can be selected by the user to be an open or closed stepper, or a servo axis. Outputs are provided for 16 bit analog servo output as well as step and direction for stepper system applications. The servo loop is a PID filter with feed-forward coefficients and an update rate of 122 ms on all 8 axes. An additional 16 User Definable I/O is available for synchronization and control of other events. In addition, independent analog inputs are provided for requirements such as velocity override, temperature, pressure, etc., under the control of the running application. Encoder feedback, differential or single ended, is used for all servo axes and is available for position feedback and may also be used for slip or stall detection. Two additional auxiliary encoder inputs are available for increased precision and control. Two additional general purpose analog outputs are also available. The bus interface uses Shared Memory technology for communication of commands from the host and feedback of motion control parameters. Commands may be written to this Shared Memory by the host, eliminating the communication bottlenecks of single address port-based communications.
