Incorrect PID Update Rate Error (-70108) with NI 7340 and NI 7350 Controllers in MAX I correctly set the PID rates in Measurement Automation Explorer (MAX) to valid values (as described in the NI 7340 and NI 7350 hardware manuals and the 'Enable Axes' VI/function help). When I try to initialize my controller from MAX, I receive error -70108 URL: http://digital.ni.com/public.nsf/allkb/C0C521CD425A253B862574400069237A

Determining the Step Length and Control Loop Update Period for Servo Tune I have a NI 7330/7340/7350 motion controller. I am using it to control a servo motor, but I am having trouble tuning it in the Servo Tune tab in the Measurement & Automation Exploxer (MAX). In the Servo Tune's Step Response tab, what is the appropriate value for Step Length? Also, in the URL: http://digital.ni.com/public.nsf/allkb/98DE5BEB4A379A4B8625730D007258AC

A Simple Method for Servo Motor Tuning I can't seem to get my servo motor tuned. Is there a simple method to find PID gains that will be give me something close to my desired response? URL: http://digital.ni.com/public.nsf/allkb/806F6F0B775FAF32862572FA0052F2AB

PCI-7390和PCI-733x有什么区别？ PCI-7390和PCI-733x运动控制器都可以工作于p-command（位置指令）模式和步进模式，这两块运动控制板卡有什么区别？ URL: http://digital.ni.com/public.nsf/allkb/6D5268422659A93E862572E0002FB820

当使用NI运动控制产品时，P-Command和Stepper两种模式有什么不同？ 我听说P-Command（位置指令）和stepper这两种模式很相似，我想知道它们之间的区别。因此，当使用NI运动控制产品时，P-Command和Stepper两种模式有什么不同？ URL: http://digital.ni.com/public.nsf/allkb/CE30DB738A91E04B862572E0003D9CFB

Closed Loop Stepper Movement is Inaccurate I have a closed loop system setup on my stepper motor to ensure that my movements are accurate; however, when I command the motor to move, it does not move to the appropriate location. Why is this happening? URL: http://digital.ni.com/public.nsf/allkb/E315EF739926310B862572CF00805A51

Timing and Programming Considerations for Onboard Motion Programming I understand that for an onboard motion application that the controller is required to provide a certain amount of time for my application. However, the program does not run deterministically. Is this expected behavior? URL: http://digital.ni.com/public.nsf/allkb/ABC7387CF365A461862572C1007CDD23
