Issue Details

I'm using LabVIEW Softmotion. When I manually command my Kollmorgen AKD drive to go to a limit, it stops as expected. But when it is on the limit and I input a command, the motor does not move. It will only move when I manually release the limit switch, and then the motor jerks quickly to the new assigned position.


Please check your settings for the limit switches in the Kollmorgen Workbench. Remove any settings related to limit switches. The limit switches in Softmotion should now work as expected. When your motor hits a limit,  it should not move further. When the motor is commanded to move off the limit switch, it should move immediately and smoothly to the new position.
