The thing that's suspicious is that 450 is the limit of rotation. I don't know which end of the movement potentiometer that represents, but you might have a loose position sense connection or dirty pot wiper. The controller would think it's not where it's supposed to be, and tries to move in that direction, eventually (hopefully) hitting the limit switch and stopping.
Is it otherwise reliable in tracking a bird during a pass? No jumps or other erratic movement?
Just a thought,

The 5500 goes up to 450 degrees in az. I use satpc-32, every once in awhile for no "forseeable " reason the rotor will park at 450 degrees. This is not what it is set for. It is a bit concerning as the coax is not the right length for that much rotation and it puts a strain on things. Any ideas?? 73 Bob W7LRD _______________________________________________ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?
