L2-06
KEB
deceleration
rate
By decelerating simultaneously
with a momentary power
interruption, this function
produces regenerative energy
and utilizes this energy to
counter the power interruption.
Select the deceleration rate to
be applied after the KEB
command (set value: 65 or 66)
set for multi-function inputs is
input.
Set as a percentage the
deceleration frequency rate for
when the time set in L2 02 has
0.0 to
100.0
0.1 NO A A A A ---
KEB
Frequency
when the time set in L2-02 has
elapsed after KEB command
input.
If 80% is set, deceleration will
be performed taking the time set
in L2-02, up to 80% of the
output frequency when KEB is
input.
If L2-06 is set to 0.0, C1-09 will
automatically decelerate to the
base so that the undervoltage
(UV) of the main circuit will not
be detected.
Note 1. The default setting depends upon the type of Inverter . The values for a 200-V class 0.4-kW
Inverter arre given above.
Note 2. These
are values for a 200-V class Inverter . V alues for the 400-V class Inverter are double.
