Claim 19:
20. A method of bending a conduit comprising:
providing a bender having a shoe mounted on shoe shaft about which the conduit is bent;
providing a microprocessor in communication with a motor, the motor configured to rotate the shoe to perform the bending operation;
providing a conduit-size switch in communication with the microprocessor, and a shoe position sensor in communication with the microprocessor;
providing a shoe position signal from the shoe position sensor to the microprocessor, providing information about the rotational position of the shoe relative to the shoe shaft;
providing a conduit size signal from the conduit-size switch to the microprocessor in response to positioning the conduit for the bending operation, the conduit-size signal providing information regarding the size of the conduit to be bent, to the microprocessor;
providing a motor control signal based upon the conduit size information from the microprocessor to the motor to control the operation of the motor; and
bending the conduit.
