Table 2: Resolution Truth Table
The Bipolar Stepper Motor Driver additional board enables you to drive the motor in various
step modes. The size of one increment (resolution) is equal to a movement of rotor generated
by one pulse on step input. The resolution is determined by logic state on MS1 and MS2
inputs as shown in Table 2.
Figure 4: Full Step mode: MS1=0, MS2=0, DIR=1
Figure 5: Half Step mode: MS1=1, MS2=0, DIR=1
Figure 6: Quarter Step mode: MS1=0, MS2=1, DIR=1
Figure 7: 8 Microstep mode: MS1=1, MS2=1, DIR=1
