3. When KEB function is enabled, the inverter decelerate to zero by 07-14, and the inverter stop
4. IF the power on signal enabled during the KEB function, the inverter accelerate to original frequency.

DC Injection Brake Level (Voltage Mode)
Range
【
0.0~10.0】%
Note: DC braking functions of voltage and current modes share two parameters of DC braking
frequency (07-06) and DC braking time (07-08).
Parameters:
(1) 07-15 is used to select DC braking mode (voltage mode or current mode)
When 07-15=0, DC Injection Brake Level is determined by 07-07;
When 07-15=1, DC Injection Brake Level is determined by 07-16.
Note: 07-07 references on rated current. 07-16 references on 20% of V/f max output voltage.
(2) 07-16 is used to set the DC braking level in the voltage mode.

08- 01 Trip Prevention Level During Acceleration
Range
【50 ~ 200】%
Trip prevention adjustment level during acceleration to prevent over current (OC-A) trips.
If trip prevention during acceleration is enabled and an over current occurs due to the load, then the
acceleration is interrupted until the over current level is dropped below the setting in 08-01 then the
acceleration is resumed.
08- 02 Trip Prevention Level During Deceleration
Range
【50 ~ 200】%
Trip prevention adjustment level during deceleration to prevent over Voltage (OV-C) trips.
If trip prevention during deceleration is enabled and an over voltage occurs during stopping due to the
load, then the deceleration is interrupted until the over voltage level is dropped below the setting in
08-02 then the deceleration is resumed.
08- 03 Trip Prevention Level During Continuous Run Mode
Range
【50 ~ 200】%
Trip prevention adjustment level during continuous Run to prevent over current (OC-C) trips.
If trip prevention during continuous Run is enabled and an over current occurs due the load such as a
sudden transient load, then the output frequency is reduced by decelerating to a lower speed until the
over current level is dropped below the preset in 08-03, then the output frequency accelerates back to
the normal running frequency.
08- 04 Over Voltage Prevention Level During Run Mode
Range
【350.0VDC~390.0VDC】(200V class) 【700.0VDC~780.0VDC】(400V class)
Over voltage prevention level can be set by parameter 08-04 when necessary.
When the DC bus voltage is higher than the level set in 08-04, the over voltage fault will occur
