0 : KEB Operation Method 1
Based on P2-04 (KEB Deceleartion Time), the drive adjusts the deceleration time during the
KEB operation to match P2-08 (Voltage Target During KEB). If power is restored within P2-07
time, the output frequency will keep the frequency of when power is restored
Note: When a Uv (Undervoltage) is triggered during KEB, set a shorter time to P2-04 (KEB Deceleration Time).
When an ov (Overvoltage) is triggered during KEB, set a longer time to P2-04 (KEB Deceleration Time).
1 : KEB Operation Method 2
The drive uses the time set to P2-04 (KEB Deceleration Time) to perform the KEB operation in
the P2-07 duration whether or not power is restored regardless the main circuit voltage. Install
a braking option as an ov (Overvoltage) might be triggered.
2 : KEB Operation Method 3
The drive uses the time set to P2-04 (KEB Deceleration Time) to perform the KEB operation and
monitors the main circuit voltage at the same time. If the main circuit voltage increases, the
drive holds the frequency to avoid ov (Overvoltage). Select this operation method when no
braking option is installed.
Refer to setting 56 KEB Command 1 (Normal Closed) and 57 KEB Command 1 (Normal Open)
of multi-function terminal inputs for details.
□
KEB Operation Start
The KEB function is triggered by the following conditions.
The multi-function input terminal assigned to KEB closes.
The main circuit voltage falls below the P2-03 level.
□
KEB Operation End
The KEB function is disabled by the following conditions.
The multi-function input terminal assigned to KEB releases after the time set in P2-07 (KEB
Detection Time).
When no multi-function input terminal is assigned to KEB and the voltage returns to the
