F6-00 = 0: Direct Start
It is applicable to most small-inertia loads, as shown in Figure 6-30 (1).
Start frequency is applicable to drive equipment which requires startup torque, such as
cement mixer, as shown in Figure 6-30 (2).
The DC injection braking function is applicable to drive load such as elevator and crane,
as shown in Figure 6-30 (3).
