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.

Set Values
•
These parameters are reference values for detecting loss of feedback for PID control.
•
Set n137 to the feedback level in percentage based on the feedback level at maximum frequency as
100%.
•
Set n138 in 0.1-s increments for the permissible continuous period of
t
he feedback signal level that is
the same as or less than the feedback level set in n137.

Set Values
•
Set this parameter to a rate by which PID control value is multiplied for PID control.
•
Normally, the default setting does not need to be changed.
•
This parameter is used for the adjustment of the PID control value to be added with the frequency
reference.

Description
0
Frequency reference control terminal for 0- to 10-V voltage input is enabled. (See note 1.)
1
Frequency reference control terminal for 4- to 20-mA current input is enabled. (See note 2.)
2
Frequency reference control terminal for 0- to 20-mA current input is enabled. (See note 2.)
3
