Stoping motion while in contour mode

[TulioB]

Hello,

I need to slowly stop the travel of a 2D vector space during a contour move (to implement a “cancel motion” feature). Can I use flex_stop_motion with NIMC_DECEL_STOP? I tried this but, its not working as I expected.

Thanks.

flex_stop_motion with NIMC_DECEL_STOP should work properly in contouring mode. Please have a look at the screenshot from a test that I have done.



This is the vector velocity profile of a 2D contouring move. At the end of this plot you can see the linear deceleration that has occurred when I sent the decelerate command. I was using a PCI-7342 with NI-Motion 7.2. Of course you will have to load the deceleration value to your vector space and not to the individual axes.

Do you see different behavior? If so what exactly are you doing?

Best regards,

Thanks Jochem,

I found what I’m doing wrong. I was setting the deceleration values after I changed the operating mode of the vector space to contour mode.
