More Schwintec problems
I spent a lot of time replacing one motor, rack and parts on one end, controller. etc..... It worked for a while now when trying to open it moves about one half inch and stops. It will reverse with no...

Oh, I must have misunderstood about the voltage.
I know my slides move much faster in override than in normal operation.
It got into my head somehow that they did PWM in normal operation to keep the motors in sync.
They move faster because they are not counting the revolutions.
So when the motors get out of sync, what does the controller do? I'm guessing interrupt power to the one that's ahead until the slow one gets caught up. From my observation,that interruption could be from fractions of a second to a second - if it takes longer than that to catch up, the controller stops both motors.
This I do not know. All I know is, to get BOTH in synch, you hold the extend or retract button for 10 seconds AFTER full retraction or extension and that always resets the counter. IF the motors get too far out of synch(Do NOT know what that parameter is) it will shut down the extension or retraction. It is VERY fast (300 rpm). Doug
