Effective when "Frequency
(speed) agree 1," "Desired fre-
quency (speed) agree 1," or
"Frequency (FOUT) detection
1," Frequency (FOUT) detec-
tion 2 is set for a multi-function
output.
Sets the frequency detection
width in Hz units.
Effective when "Desired fre-
quency (speed) agree 2," "Fre-
quency (FOUT) detection 3,"
or "Frequency (FOUT) detec-
tion 4" is set for a multi-func-
tion output.
Frequency that should be
detected is set in Hz units.
Effective when "Frequency
(speed) agree 2," "Desired fre-
quency (speed) agree 2," Fre-
quency (FOUT) detection 3 or
"Frequency detection 4" is set
for a multi-function output.
Frequency detection width is
set in Hz units.
0: Stop (Operation follows the
frequency reference.)
1: Operation at 80% speed
continues. (At 80% of speed
before the frequency
reference was lost)
Frequency reference is lost:
Frequency reference dropped
over 90% in 400 ms.

Sets the number of auto restart
attempts.
Automatically restarts after a
fault and conducts a speed
search from the run frequency.
Sets whether a fault contact
output is activated during fault
restart.
0: Not output (Fault contact is
not activated.)
1: Output (Fault contact is
activated.)
