DC injection braking
After the stop command is input and the minimum baseblock time (L2-03) has elapsed, DC
injection braking is applied and the motor stopped.
The DC injection braking time depends upon the output frequency when the stop command is
input and the “DC injection braking time at stop” setting in b2-04, as shown in Figure 6.6.
Output frequency
Fig 6.6 DC Injection Braking Stop
Lengthen the minimum baseblock time (L2-03) when an overcurrent (OC) occurs during stopping. When the
power to an induction motor is turned OFF, the counter-electromotive force generated by the residual magnetic
field in the motor can cause an overcurrent to be detected when DC injection braking is applied.

After the stop command is input, run commands are disregarded until the time T

has
elapsed. The time T
0
depends upon the output frequency when the stop command is
input and the deceleration time.
