Lots counting errors at using the DDCSV with MPG

ytliu

Set # 448 (MPG control mode) parameter to 0 (open) to solve this problem

Under the precise control mode of mpg(#448=0), after the handwheel stops shaking, the corresponding axis still moves until all the pulses in handwheel buffer are sent;Otherwise, once the handwheel stops shaking, the corresponding axis immediately decelerates stop.

Hello,
Parameter #448 is added in the newer version, the new version can be downloaded from http://www.ddcnc.com/forum.php?m ... &extra=page%3D1 post

Hi DAMIGO!
When turn the handwheel, if the screen coordinates only a small amount of change, the reason is generally handwheel A / B signal missing all the way caused。
Can judge the reason of the problem like this:
Disconnect handwheel B signal from controller, then turn handwheel，If the screen coordinates are still a slight change, the hand wheel A phase signal is connected to the controller B phase signal port，Then turn the handwheel, if the screen coordinates is still a slight variation, indicating the hand wheel problem, if the screen coordinates no change, indicating the controller problem.
If it is a controller fault, you can contact the dealer to replace, you can also locate and repair the fault,The figure is a schematic diagram of the handwheel coded signal.
If FPGA_WHA, FPGA_WHB signal waveforms are correct, then I'm sorry, you can only contact the vendor for replacement.

Hi DAMIGO!
You said the problem should be caused by cumulative error, you can set "the pulse equivalency" to 1000 (there will be no cumulative error), and then observe the hand wheel running state.What is your current pulse equivalent setting?
