System Schematic
The Qube-Servo 3 provides a USB interface for use with a computer.
The interaction between the different system components on the Qube-Servo 3 is illustrated in Figure
2.1. On the data acquisition (DAQ) device block, the motor and pendulum encoders are connected to
the Encoder Input (EI) channels #0 and #1. The Analog Output (AO) channel is connected to the power
amplifier command, which then drives the DC motor. The DAQ Analog Input (AI) channel is connected
to the PWM amplifier current sense circuitry. The DAQ also controls the integrated tri-color LEDs.
