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

Breakpoints与模拟反馈信号 我有一块PCI-735x运动控制板卡，我想根据模拟反馈信号来产生breakpoint输出。NI的运动控制器支持模拟反馈信号的breakpoints功能吗？如果不支持的话，那么还有别的选择吗？ URL: http://digital.ni.com/public.nsf/allkb/9177F52240DF21D8862572C4003F1044

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

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

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

Creating Custom Cables for NI Motion Controllers (733x, 734x, 735x) I do not see a cable suitable for my needs, so I would like to create my own custom cable. What are the needed connectors and who makes them? URL: http://digital.ni.com/public.nsf/allkb/569A8CC853124528862572A0005CD5E4

Conversion Factor on the NI 9505 The NI 9505 is a Servo Drive module that can be used for current loop control algorithms. These algorithms require the user to specify the Current Setpoint and Current Limit (Amps) as floating point [DBL] numbers. Because the FPGA on the NI 9505 does not currently interpret URL: http://digital.ni.com/public.nsf/allkb/0E95A86A1323EBD38625729E000BD4A1

NI 9505上的转换因数 NI9505是一块伺服驱动模块，可以用在电流控制算法回路中。在这些算法中，需要用户以浮点数的形式（DBL）指定电流的Setpoint和极限值(以安培为单位)。由于与NI 9505一起工作的FPGA目前还不能支持浮点运算，所有，所有的浮点数都必须被转换成整数。■> URL: http://digital.ni.com/public.nsf/allkb/BAACFF6AA68E4037862573C5003A88BD

Where Can I Find The Warranty For My NI Hardware? I'm trying to find the warranty information for my NI hardware. Where can I find it? URL: http://digital.ni.com/public.nsf/allkb/8341879DC763DF5886257289005D816E

Configuring Axis Resources for a Motion Dual-Loop Feedback System I would like to use dual encoders, but I only have two axes on my MID. Measurement & Automation Explorer (MAX) defaults dual encoding to Axis 1 and 3, but I need to figure my second feedback encoder to a different axis on my UMI. Is this possible?
