Set parameter 07-06, 07-08 and 07-16 for DC injection braking related function.
When inverter executes speed search function, DC injection braking function should be
disabled.
To enable DC injection braking during a start operation set the DC injection braking current
(07-07) and the DC injection braking time (07-16) at start to a value greater than 0. DC injection
braking at start can be used to prevent
“
wind milling effect
”
in fan applications.
To enable DC injection braking during a stop operation set the DC injection braking current
(07-07) and the DC injection braking time at stop (07-08) to a value greater than 0.
When parameter 07-16 is set to 0 sec (DC injection braking off). the inverter will start from the
minimum output frequency duration of DC injection braking during a stop operation. DC
injection braking at stop is disabled when parameter 07-08 is set to 0 sec. If output frequency is
less than 07-06, injection braking function will be enabled. Inverter output will be cut off and
then DC injection braking is started.
During stop operation: If the DC braking start frequency < minimum output frequency (01-08),
DC braking is active when the output frequency reaches the minimum output frequency level.
DC injection braking level can be set by parameter 07-07 in acceleration and deceleration, DC
injection current can be part of output rated current. (Suppose rated current of inverter is
100%)
Increasing the DC braking current (07-07) can reduce the motor stop time.
DC braking operation can be controlled via any one of the multi-function input terminals(03-00
to 05) function 33. Refer to figure 4.3.

PMSLV is available for short-circuit braking. Short-circuit braking is the way to switch IGBT to
produce braking torque. 07-06, 07-34 and 07-36 can adjust the braking process.
If 07-35=0, Inverter start from the minimum frequency.
The value of 07-36 is depend on differential motor rated current.
03-00~03-07=65 can control Short-circuit braking.

When a stop command is issued the inverter stops according to the stop mode selected. There are
four types of stop modes.
Note:PM motor only can select
“
deceleration to stop mode
”
and
“
coast to stop mode
”
