Vcc2 (5V) : Power Supply for internal logic IC
[Operation Guide]
1. Motor Connection:
Connect the motor to OUT1 and OUT2.
2. Initial Condition Setting:
Set to signal condition IN1=H, IN2=H, and INH=L.
3. Power Supply:
At first, supply DC voltage to Vcc2(5.0V).
Next, supply DC voltage to Vcc1.
4. Set to Forward or Reverse signal condition with INH=Low.
Turn “High” INH signal.
Output current flows between OUT1 and OUT2.
5. Motor Operation
