How precisely can forces and torques be controlled with the MTR-AC?
In conjunction with the SEC-AC, our MTR-AC servo motors can be operated in position control, speed adjustment or torque control modes. It is important to bear in mind that in torque control mode only the motor current is measured and adjusted. The motor current is proportional to the torque of the motor as long as friction influences are negligible and the motor is not in a state of magnetic saturation. This means that torque control is indirect and friction influences cannot therefore be corrected. Therefore, the expected precision of the force or torque cannot be higher than the friction forces that are present.
