ELECTRONIC OVERVIEW –T561 MOTOR CONTROLLER PCB - Continued

Section 4

Functional Description

The Motor Controller PCBs are designed to act as an interface between the Drive motor, Display Console, and the

Incline Motor. The desired belt speed and elevation is sent down to the motor controller and incline motor via the users

selected input into the console. The motor is driven by a fixed frequency variable duty cycle signal. If an error

condition is detected the main power relay receives its bus voltage from the console through the emergency pull switch.

This relay can be energized by having the emergency pull switch in its proper place. Opening of the relay does not

remove power to the console or the logic on the motor control board, but will interrupt power to the incline and drive

motors.
