FB_BA_Motor2St
The function block FB_BA_Motor2St is used to control 2-step motors.
The input bEn is used for enabling the function block.
The input nOpMode is used to set the operation mode of the motor:
- 0 = Automatic
- 1 = Manual off
- 2 = Manual step 1
- 3 = Manual step 2
In automatic mode (nOpMode = 0) the desired step can be set via the inputs bAutoSt1 (step 1) and bAutoSt2 (step 2).
The collection of all possible malfunctions of a motor is connected to bDst.
