·
Set the value in percentage based on the maximum frequency as 100%.
·
The integral upper limit is set so that the output frequency will not be excessively high
when the deviation is large.

Set Values
·
Set this parameter to the primary delay time constant for the frequency reference after
PID control.
·
Normally, the default setting does not need to be changed.
·
If load is a mechanical one with high viscous friction or low rigidity, the load may reso-
nate. If that happens, set a value larger than the resonant frequency of the load so that
the load will not resonate, even though the response will be slower.

Value Description
0 Feedback loss detection disabled
1 Feedback loss detection enabled (Nonfatal error: FbL warning)
2 Feedback loss detection enabled (Fatal error: FbL error)
Note 1. Set the method of detecting loss of the feedback as a detected value for PID
control.
Note 2. If the detection level set in n137 or lower is detected for the set time in n138, the
result will be determined as feedback loss.
