Excitation Sequence
When the voltage signals shown in Figure 3-6 are input to the motor drive circuit shown in
Figure 3-5, as shown in Table 3-3, the LTP F Series feeds the paper in the normal direction
when the motor is excited in the order of step 1, step 2, step 3, step 4, step 1, step 2, . . . .
Figure 3-5, as shown in Table 3-3, the LTP F Series feeds the paper in the normal direction
when the motor is excited in the order of step 1, step 2, step 3, step 4, step 1, step 2, . . . .
