5. LOADING, CHANGER DRIVE CIRCUITS
Notes:
V
CTL
: When the motor speed control voltage is permitted between 0V ~ 4V, the motor varies its speed.
Between 4V ~ 5V, the motor can be used at constant speed and over 5.8V, the motor should not be used.
Furthermore, when V
CC
= 5V, CTL voltage should not be permitted to exceed 3V
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.
