. When the operation command (forward or reversal) is OFF, when the output
frequency decreases to DC braking start frequency (07-06), and the DC braking will
perform this function based on the DC braking execution time (07-08), please refer
to Figure 4.3.62 to understand the operational details of pre-excitation operation.
