6.9 FULL-RANGE DC INJECTION BRAKING STOP (DCB STOP)
Sn-04 = 10XX, Cn-12
When the full-range DC injection braking stop function is used, the inverter can be stopped without a braking
resistor. When stop command is input, DC injection braking stop is executed. DC injection braking time while
stopping is set by Cn-12 at 10% speed and varies according to output frequency at stop command input as
shown below.
