Yes A2 is negativ and A1 and A3 is positive, i was wrong about that because i did not have that contactor in front of me when i wrote it I just assumed.
Before the turning of the engine (signal from A3 to A1 the engine would have been stopped by sensor so it wil have a "break" before change of signal.
Engine is used to rotate a arm with a pipe, i have basicly 2 types of these.
1. big pipes and 3 pipes on one arm
2. small pipes and 24 - 32 pipes on one arm.
this problem only happends on the small pipes with 24-32 pipes on it. why is this so? Is this because this engine wil have more movement (contactor would be used more) ?
thanks for all the answear, i realy hope this wil help on my problem. i will certainly try it out .
If this works out i wil reply here
