Description

When the VFD starts in direct start mode
(P01.00=0), set P01.30 to a non-zero value to
enter short-circuit braking.
During stop, if the running frequency of VFD is
lower than the starting frequency of brake for
stop (P01.09), set P01.31 to a non-zero value to
enter short-circuit braking for stop, and then
carry out DC braking in the time set by P01.12.
(See descriptions for P01.09–P01.12.)
P01.29 setting range: 0.0–150.0% (VFD)

Speed tracking method
0: From stop frequency (Usually selected)
1: From low frequency (Applicable to restart
after a long time of stop)
2: From max. frequency P00.03 (Applicable to
common power generation load situation)
1–100
A great value of this parameter indicates a fast
rotation-speed tracking speed, but an
excessively great value may result in poor
tracking effect.
30%–200% (motor)
Great great value of this parameter indicates
