My setup consists of a NEMA 42 Brushless gear motor (with hall effect and absolute encoders), a big 100Ah battery and the Roboteq controller (MBL1660A). Motor weights like 12 Kg. I have been running this setup just fine for over 2 years in closed-loop speed position. FW version 1.8d
Since switching over to v2.0 and 2.01, my motor no longer moves. any attempts at tweaking the PID makes it go crazy and jerks a lot! (like it is about to destroy itself)
even having value as P = 0 I = 0.1 and d=0 makes the motor jerk very violently.
