Notes:

A servo drive receives a command signal from a control system, amplifies the signal, and transmits electric current to the E3R Platform gyro motor in order to produce motion proportional to the command signal. A sensor attached to the gyro motor reports the motor's actual status back to the servo drive. The servo drive then compares the actual motor status with the commanded motor status. It then alters the voltage frequency or pulse width to the motor so as to correct for any deviation from the commanded status.
