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

Import Motion Controller Configuration Settings from Different Language Operating System I would like to export my motion controller configuration settings from one language specific Operating System (OS), and be able to import those settings on another computer with an OS of a different language. Can I import the configuration data of MAX from other language Windows OS? URL: http://digital.ni.com/public.nsf/allkb/3F329E0ED9D595AD862572ED00615965

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

Tuning a Motion Controller for Different Dynamics Forward and Backward I have a closed-loop system that is driven by a 7340 motion controller. The load moves in the vertical direction. Due to the effects of gravity, I have different loading parameters when traveling downward opposed to traveling upward. How can I tune my motion control card to compensate for the URL: http://digital.ni.com/public.nsf/allkb/8108FBCAF15FDEE0862572DE0071AE6B

前向或后向运动中调整电机控制器的参数 我有一个用7340 motion控制器驱动的闭环系统。负载进行垂直方向运动。因为重力的影响，相对于向上运动，我有不同的负载参数用于向下运动。当进行上下不同方向运动时，如何调整motion控制卡的参数来补偿变化的运动？ URL: http://digital.ni.com/public.nsf/allkb/8E8F8818E391AAD9862574000018BBB7

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

Error 12 Installing NI-DNET Hardware With an NI-CardBus 8310 Connection I have a PPC-2015 controller that is connected to my PXI chassis through a CardBus 8310. When trying to install my NI-DNET PXI-8461, I get error 12 in the Windows Hardware Installation Wizard. How do I get my PXI-8461 to install and work with my system?

Error -70207 when Initializing a PCI-7390 Motion Controller When initializing my PCI-7390, I recive the error -70207 says 'The move cannot be completed because the inhibit input of the commanded axis is active.' Why am I getting this error, and what can I do to initialize the board without getting this error? URL: http://digital.ni.com/public.nsf/allkb/E55301855F60C9DA862572C20065ECD4

Implementing Feedforward Position Component on NI-Motion Controllers How can I implement a feedforward position component to my system if I know that my load will vary linearly as I move away from the zero position? URL: http://digital.ni.com/public.nsf/allkb/53BF23F982C3BF17862572AD00701503
