K Continuing Operation at Constant Speed When Frequency Reference Is
Lost
The frequency reference loss detection function continues operation using 80% speed of the frequency refer-
ence before loss when the frequency reference using an analog input is reduced 90% or more in 400 ms.
When the error signal during frequency reference loss is output externally, set H2-01 to H2-03 (multi-function
contact output terminal M1-M2, P1-PC/M3-M4, and P2-PC/M5-M6 function selection) to C (frequency refer-
ence lost).

*For (-E) models only. Otherwise always 80.0%.

K Restarting Operation After Transient Fault (Auto Restart Function)
If an Inverter error occurs during operation, the Inverter will perform self-diagnosis. If no error is detected, the
Inverter will automatically restart. This is called the auto restart function.
Set the number of auto restarts in parameter L5-01.
The auto restart function can be applied to the following faults. If an fault not listed below occurs, the protec-
tion function will operate and the auto restart function will not.
*When L2-01 is set to 1 or 2 (continue operation during momentary power loss)
