The operator will start the device and use the speed and incline keys
to control motors. When the speed key is pressed a signal is sent to
the AC motor inverter to request a change. The inverter will then send
the appropriate amount of power the AC drive motor to reach the
requested speed. The motor drives the front roller (which in turn
moves the walking belt) through pulleys and fan belt. The incline
motor is operated when the operator presses the incline keys. A
command is generated that is transmitted to the incline control board
where a relay is energized sending AC power to the motor until it
reaches the desired position.
