This function is to achieve
stable DC bus voltage in case
of deceleration. DC bus volt-
age rises due to regeneration
during deceleration. When
this function is
(= or ), inverter con-
trols the deceleration time so
that the DC bus voltage not to
go up to the overvoltage trip
level, and leads to the trip-
less operation during deceler-
ation.
Please note that the actual
deceleration time can be lon-
ger in this case.
