Hello
I'm trying to configure a motion control system using a PXI platform. The main software I'm using is:
NI LabVIEW 2010 SP1
NI LabVIEW 2010 SP1 Softmotion Module
NI LabVIEW 2010 SP1 Real Time Module
NI LabVIEW 2010 SP1 FPGA Module
and the following hardware:
NI PXI 8102 Controller
NI PXI 7842R RIO Module
NI 9151 R series expansion chassis
NI 9474 module https://www.ni.com/en-us/shop/model/ni-9474.html
NI 9411 module https://www.ni.com/en-us/shop/model/ni-9411.html
I started with example code (Servo interface labview project from labview help). I've already been able to perform initial configuration of the system using "General Settings". There are no error messages. I can move the motor using the "Interactive test panel" but sometimes the movement is not smooth. Since I don't know exactly the behaviour of the system, I wanted to evaluate its step response but it didn't work (no response of the motor). In addition I tried to move the axis using a function block available in the project but the stage moves erratic.
My questions are:
Why I can not to perform the step response of the system?
Why I can move the motor using "Interactive test panel" but not using function blocks from LabVIEW.
Is it necessary to make some kind of sincronization between RT and the FPGA or any other hardware/software to improve performance of the system?
Thanks to everybody
Edo
