* The inverter’s overload protection sensitivity is increased during DC injection braking, so if
d b C
is set
to approx. 90% or higher, the electronic thermal overload protection may activate depending on the
d b t
setting.
(The overload protection will activate in approx. 3 sec. when
\ d b C
is set to 100%.)
