DC Braking Stop (b1-03 = 2)
(DC Injection)
Note: Lengthen the min. baseblock time (L2-03) when an over-
current (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 mo-
tor can cause an overcurrent to be detected when DC
braking is applied.
Note: After the stop command is input and the minimum baseblock
time (L2-03) has elapsed, DC braking is applied and the motor
stopped. The DC braking time depends upon the output fre-
quency when the stop command is input and the “DC braking
time at stop” setting in b2-04, as shown in the graph below.

Note: After the stop command is input, run commands
are ignored until the time t

has elapsed. The time

depends upon the output frequency when the
stop command is input and the deceleration time.
