I have an application where I want to follow a path in (position, velocity, time). A host computer will provide a new position and velocity every 10ms, indicating where the axis must be on, e.g., the next but one 10ms tick. I want PMAC to execute PVT commands to follow the commanded positions. The timing accuracy of commands must be ~10us. In the past I have handled a similar application using PMAC's DPRAM to pass positions from the host to the motion program, with some flags in the DPRAM to control the data flow. Is there a way to pass positions to a motion program in power PMAC with this type of timing synchronization?
