Hi
I have a 1769-L27ERM with Kinetix 5500 and CIP motion. The application is a centre driven rewinder.
I want to turn a shaft through a fixed number of turns (at fixed speed) to engage the material, then switch to a torque limit, with maximum speed applied. Torque will then be gradually increased as diameter does. When the material is cut I want to go back to position mode and finish the winding, then come to rest at a known shaft angle.
My difficulty is that it looks like the axis can only be switched between these modes by a download. I can see that I can change the max/min torque (in position mode) and it takes effect immediately, but then the axis ultimately trips on speed error if torque limit is reached before speed is achieved.
Can anybody point me towards a solution? Thanks!
