※Note:
1. When 04-11≠0, the momentary power loss and Restart is disabled, the inverter will do KEB
Function.
2. When input power is turned off, CPU detects the DC bus Voltage and as soon as DC bus Voltage
becomes lower than190V (220V system) or 380V (440V system), then the KEB function is
activated.
3. When KEB function is enabled, the inverter decelerate to zero by 04-11, and the inverter stop
4. IF the power on signal enabled during the KEB function, the inverter accelerate to original
frequency.
04-12: Lower Limit of Power Voltage Detect = 150.0 ~ 210.0/300.0 ~ 420.0
04-13: DC Injection Brake Level(%) @start = 0.0 ~150.0
04-14: DC Injection Brake Time (Seconds) @start = 0.0 ~ 25.5
04-15: DC Injection Brake Start Frequency (Hz) @Stopped = 0.10 ~ 10.00
04-16: DC Injection Brake Level (%)@Stopped = 0.0 ~ 150.0
04-17: DC Injection Brake Time (Seconds)@stopped = 0.0 ~ 25.5
1. 04-17 / 04-15is the action time and start frequency of DC braking, as graph below:
