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
Does the software have an antenna parking setting?

Which rotator controller are you using with your 5500 ? Did you configure your Rotator to be 450deg in SATPC32 ?
Some controllers like EA4TX have the smarts to utilize 450 deg even if your software is configured for 360 For example if your rotator is sitting at 350 degs and you tell it to go to 45 degs, it goes to 360+45 405 deg 'cause it's closer. SATPC32 software itself may do that also if configured for a 450 deg rotator. I'll test to see what it does. I've got a G-5500 setup.
If your park position is set for 90 degs, you might try making it 91 degs (451 degs).

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,
