Re: URGENT: NQC problem

It sounds as if your problem is being caused by the motor being 'back driven' when switched off. Possible solutions:-
1) Don't turn the motor power completely off - reduce the power level to the point where everything stays put.
2) Implement a lock or latch that engages to hold position
3) Use gears with higher friction to drive things up and down - for instance, worm gears do not usually suffer from being back driven
Have fun ! Dave

Hi Dave, thanks for the answer, the problem is that the minimal power (1) is too much, the rotor must not turn but only stay in position, or extremely, to turn but with the minimal strong! Do you know the solution in NQC? I didn't know so good the NQC, maybe I didn't see a function that can help.
