0 No
General deceleration
is carried out until a low
voltage trip occurs.
1 KEB1
When the input power
is lost, it charges the
DC
link with
regenerated energy.
When the input power
is restored, so does
normal operation from
energy
buffering
operation to the
frequency reference
operation. Operation
frequency acceleration
is set in Cn.83.
2 KEB2
When the input power
is lost, it charges the
DC
link with
regenerated energy.
When the input power
is restored, it changes
from
the energy
buffering operation to
the deceleration stop
operation.
The
operation frequency
deceleration time is set
in dr.4.
Cn.78
[22]
Initial value for
KEB operation 125.0% 110.0 to
200.0%
Sets the start and stop points of the kinetic
energy buffering operation. The set values
must be based on the low voltage trip level
as 100% and the stop level (Cn.79) must be
higher than the start level (Cn.78).
NO
Cn.79
[22]
Value to stop
KEB operation 130.0% Cn.78 to
210.0%
NO
[22] Displayed when Cn.77 is not set to 0 (NO).
