Switch Feedback on the Fly
Consider a heat-sink assembly application where a position sensor is the feedback device for the initial positioning along the Z axis. However, when the heat sink is pressed on to the PCB, a force sensor must be the feedback device for precise motion control in the latter part of the process. With NI motion controllers, you can switch feedback devices on the fly without reinitializing the controller. The new feedback device might require the system to have a new set of PID gains loaded immediately after the axis is reconfigured. To minimize the delay, you can configure an additional set of PID gains with the motion controllers.
anyone can give me some detailed materials about "switch Feedback on the Fly", for example, some programme,some words to explain it.
another question is that if i don't use the torque sensor, can i directly use the DAC to control the voltage to come true the torque control?
Thanks for your answer
