Abstract: Make-up speed for a tongs drive system is monitored and controlled to maintain the speed within a limited target range either throughout the make-up process or during the final portion of the make-up process, thereby improving make-up consistency and allowing for improved evaluation or torque during the make-up process. An encoder generates speed and position data during the make-up process. The speed data is compared to a target speed, which is based on rod and/or tongs characteristics.
