Classification: CPC B | IPC B

Claim 16:
17. A method of bending a conduit comprising:
providing a bender including:
a frame;
a shoe rotatably mounted on the frame;
a motor configured to rotate the shoe;
a microprocessor in communication with the motor;
an engagement member mounted on the frame and reciprocally movable to engage with, and disengage from, a switch, based on contact between the engagement member and a portion of the conduit;
the switch in communication with the microprocessor and in communication with the engagement member;

displacing the engagement member via contact with the conduit, the engagement member moving relative to the frame causing the engagement member to engage the switch;
sending, via the switch, a signal to the microprocessor indicative of a characteristic of the conduit to be bent, in response to engagement with the switch;
providing a feedback circuit in communication with the motor and the microprocessor, the feedback circuit determining a voltage consumption and a current consumption of the motor, and wherein the voltage consumption and the current consumption together correspond to a power consumption of the motor; and
providing a motor control signal from the microprocessor to the motor to control a rotation of the shoe in response to the measured power consumption of the motor.
