Ok, I've made some tests on my P2DX differing turnrates (all rad/sec): 1. 0.174 and -0.174 - turns slowly, not jerking, not beeping 2. 0.1 and -0.1 - stalled, not beeping 3. 0.114 and -0.114 - turns even slower, not jerking, not beeping 4. 0.113 and -0.113 - stalled, not beeping Looks like there's a threshold around 0.114 under which it cannot move at all. These beeps on your Pioneer suggests something is wrong. On P2DX for example repeating beeps can be heard whenever battery power goes down below some threshold.
