DC Injection to Stop DC braking stop: Stops faster than free-run, without regenerative operation.

Coast w/Timer
Free-run stop with timer: Run commands are ignored during deceleration
time.
The following diagrams show the operation of each stopping method. The “deceleration time” in the
diagrams refers to the selected deceleration time. (Deceleration times 1 through 4 are set with
C1-02, C1-04, C1-06, and C1-08.)
Deceleration Stop (b1-03 = 0)
Note
1. Decelerates to a stop at a rate set with the
selected deceleration time.
Note
2. If the run command turns back ON during
deceleration, deceleration will be stopped
as soon as the run command turns ON and
the motor will be accelerated at the speci-
fied frequency.

Run command
Free-run Stop (b1-03 = 1)
Note
1. After the stop command is input, run commands are ignored until the minimum base-
block time (L2-03) has elapsed.
Note
2. Do not input the run command again until the motor has slowed down sufficiently. If
the run command turns ON, the motor will rapidly decelerate to a low frequency, and
a main circuit overvoltage (OV) or overcurrent (OC) will be detected. If necessary,
use a timed free-run stop and set the deceleration time to a value large enough to
ensure sufficient deceleration (restarting is not possible during the deceleration
time). Use one of the multi-function inputs 1 to 6 (H1-01 to H1-06) for a speed search,
find the speed during the free-run stop, and ensure that acceleration is smooth.
The inverter output is shut OFF
when the stop command is input
and the run command goes OFF.
