Get the angular motor mode. The mode parameter will be one of the following constants: dAMotorUser: The AMotor axes and joint angle settings are entirely controlled by the user. This is the default mode. dAMotorEuler: Euler angles are automatically computed. The axis a1 is also automatically computed. The AMotor axes must be set correctly when in this mode, as described below. When this mode is initially set the current relative orientations of the bodies will correspond to all euler angles at zero.
