Is there a way to track a curve but limit the acceleration/speed etc just like the track position command where it will “try” to follow the curve but with set limits.

Thanks

Run the curve on a virtual axis, then do either 1 or 2:

1. Send the Track Position command to your control axis to try to follow the curve.

2. Or, use dynamic retargeting, which involves making a one-step user program that continuously sends the Move Absolute command to follow the virtual axis. This requires setting the Requested Jerk axis parameter to zero in order to work.
