5. LOADING, CHANGER DRIVE CIRCUITS

Notes:

Between 4V ~ 5V, the motor can be used at constant speed and over 5.8V, the motor should not be used.

The logic signals, input from the MCU, is inverted in the inverter and can control the changes of the output properties, that

depend on the input signal. There properties are shown in the table below.

Notes:

The bias voltage Vr is expressed as below;
