Abstract
A digital robot control includes a position/velocity microprocessor control and a torque microprocessor control for each of multiple robot axes. Digital position, velocity and motor current feedback signals are generated from motor sensor signals for use in making microprocessor control calculations. A backup velocity determination is made for each joint motor by the torque microprocessor from the motor current feedback, the motor command terminal voltage and the motor resistance and inductance. The robot is shut down if the difference between the feedback and backup velocity values exceeds a predetermined limit.
