* DC injecti
on
braking is a function that forcibly stops the motor,
so
do not set
Id
b
[I
or
Id
bl= I higher
than necessary,
as
the motor may overheat.
* The inverter's overload protection sensitivity is increased during DC injection braking, so
if
Id
b C I is
set to approx.
90% or higher, the electronic thermal overload protection may activate depending on the
Id
bl= I setting.
(The overload protection will activate in approx. 3 sec.
whenldb[
I is set to 100
%.
