Operating Modes
  • Mode 0: Angle servo mode (default mode, absolute position controllable from 0-360 degrees)
  • Mode 1: Motor constant speed mode (maintains speed without deceleration as the load increases)
  • Mode 2: Motor constant current mode (maintains current without decreasing with increasing load); can achieve absolute position
Constant force output Set the output torque value; the servo can maintain this torque (input the target torque value corresponding to address 44, the servo can maintain this torque)
Multi-Loop Mode Control of positive and negative 7 turns at the highest accuracy, but the number of power failure turns is not saved (the resolution can be expanded, and the number of turns can be doubled)
Command signal Digital Packet
