Abstract
A control system for a weld motor for a strapping machine is based upon the number of rotations of the weld motor. The system is used in a strapping machine of the type having a body, an anvil mounted to and movable relative to the body, a sealing member disposed for oscillating movement relative to the anvil and a motor operably connected to the sealing member to provide oscillating movement to the sealing member. Movement of the sealing member seals overlying courses of strapping material to one another. The control system includes a sensed element located on a rotating portion of the motor, a sensor for generating a signal at each instance of sensing the sensed element, a counter operably connected to the sensor for counting the instances of the sensed element and a controller for controlling operation of the motor based upon the counting of the instances of the sensed element. A method for controlling a motor is also disclosed.
