Control Modes & Basic Operation

The arms support force control via joint torque sensing. Switch between the following modes depending on the task.

ModeOverview
Position controlMove to joint or Cartesian targets; supports MoveJ / MoveL
Joint impedance controlSet stiffness and damping per joint for compliant motion
Cartesian impedance controlSet stiffness and damping in the base frame, for contact-rich tasks
Force control (Cartesian impedance + force)Hybrid force/position control applying a set force along chosen axes
Direct teaching (joint / Cartesian)Teach poses by moving the arm by hand
PVT modePlay back position–velocity–time trajectories

Tool (payload) identification

After changing the gripper or hand, return to home and run the identification trajectory in PVT mode to identify payload mass, center of mass and inertia. This affects the accuracy of impedance and force control.

Handling faults

  • Clear servo errors, read error codes and soft-reset joint motors from the control software.
  • Pressing the emergency stop halts all axes and engages the brakes.
  • Forced brake release can let the arm drop. Always support the arm and follow the procedure in the manual.
Caution: back up the original configuration files before changing IP addresses, payload, stiffness, damping, home position or TCP offset.
