new motor issue

[techno935]

I'm at 80.1 West longitude:

My motor refuses to go anywhere west of 129 West and no where further east of 43.1 West. Is this a limit issue? Doesn't sound like it. I thought the motor had 70 degrees of leeway. Maybe I'm wrong?


It's a Stab HH90 motor.

You may be hitting Usals limit. Try 1.2.

no limits according to the manual but I'll have to do some tinkering. If anyone else wants to chime in, feel free.

Welcome to the HH90 Stab motor craziness. I have HH90 myself and for the longest time I keep thinking the motor has gone crazy. Sometimes it will turn to true south when it is suppose to go to a different location....etc. I came to a conclusion that coax cable length DOES make a difference. Try reduce the length of you cable or try a shorter run into the motor and take it to the location west of 129 West, see if it works.

I am in Toronto 79.2 W, with the same dish and motor setup I am able to get 30W to 129W most likely you need to some tuning on your motor, it looks you are below the Clark belt on the east side. I had similar problem.
The motor limits are Rotation Angle ±65° that means 80-60=20°
