It's an odd issue.
It acts like the servo motor controller is not finding an input signal from a needle positioner, but the CSM1000 doesn't have an NPS and the controller doesn't have a place in the menu item to say an NPS is present when it is not.
The problem is reminiscent of what happens when someone puts a speed reducer on a machine that has an NPS. The controller can't get the signal from the NPS within the specified number of motor rotations so it goes a little nuts looking for one before hitting the "timeout/lack of signal" and shutting down. But all y'all don't have an NPS or a speed reducer.
Perhaps it is a controller fault, but it is very odd that it would only do it once. The controller usually works right or doesn't really work at all.
If it is a linkage hanging up then, instead of simply lifting off of the treadle, do a strong heel-rock back. That will force the linkage to go back over center into the heel-rock zone of the treadle position sensor and won't let the linkage hang up. If that fixes it, then you know it's a problem somewhere between the floor and the treadle position sensor. ;^)
If you are lubing things, don't forget to lube the treadle pivots. Even though the treadle pivots are crudely made they seldom give any trouble, but as long as you're up...
