Controller rotational instructions
1. After key switch ON
When the transistor on the CW side of the controller is
turned ON, 5V from a driver circuit drops to ground. At
this point the CW line is 0V and CCW line is 5V at the
driver side.
➡ ➡
CCW5V
CW0V
2. After CW side limit switch ON
The controller turns OFF the transistor on the CW side,
and turns ON the CCW side on the driver. CW line is 5V
and CCW side is 0V.
➡ ➡
CCW0V
CW5V
3 . The stop status in volume position
CCW and CW of a transistor are turned OFF, and both
lines at the driver side are 5V.
