Notes:
When 07-
14≠0, Inverter will perform a KEB function when momentary power loss and auto-restart are
disabled,
When input power is turned off, CPU monitors the DC bus Voltage and when the DC bus voltage level falls
below 190VDC (230V system) or 380VDC (460V system) KEB function is activated.
When KEB function is enabled, the inverter decelerates to zero based on parameter 07-14 after which the
inverter will stop.
If power is restored while KEB is active the inverter accelerates back to its original frequency.
