Reset of OnlinePathInfluence in mappMotion

Hello,

I have a question regarding the MC_BR_OnlinePathInfluence_N block.

As I understand, this FUB allows me to add an Offset to the axis during the CNC Run.

So X100 from the CNC + 20 from the offset would add up to 120.

If i would now set the Offset back to zero, I would get:

X100 + 0 Offset = 100.

What I want to do is reset the Offset which results in the following:

X120 + 0 Offset = 120.

So basically, I want to add the offset to the base axis value while the cnc is running. This switch should also not cause any movement.

In ACP10/ARNC0 we solved that with custom ail code. I’m hoping there is a more elegant solution in mappMotion.

Thanks,

Martin

Hi @mreiter ,
I see in the Help we have some notes about MC_BR_OnlinePathInfluence_N Description but you know there are so many possible combinations you can have on your cnc program (G04,G172, M-Function,CDC,restart…) not all documented. I recommend to implement a simple cnc program to study all your use cases (with arsim, in simulation) and trace the axis position, as R&D did:

Hello,

The MC_BR_OnlinePathInfluence_N was intended to use only for small Offsets in the UseCase for a Distance Control or Similar.
There is currently no one cycle trick to remove the offset while updating the position in cnc system.

While the CNC-Program is active and MC_BR_OnlinePathInfluence_N is Enabled, the Inputs of the Functionblock must be contious.

If the ARNC0 use Case was to implement a Tracking Functionality i would recomment to use the Tracking build in MappMotion, because it is much more advanced as the OnlinePathInfluence.

If this is not a Tracking Use Case i would recomment to get in Contact with you local Support and Discuss the AIL UseCase with the Development Team to find a MappMotion alternative. AIL is still in MappMotion available. But the old AdditiveElement-Inputs of the TRF are no longer available.
