Speed agree detection Effective when "Desired fre-
level quency (ref/setting) agree 1,"
"Frequency detection 1," or
"Frequency detection 2" is set
for a multi-function output.
Spd Agree Level
Frequencies to be detected are
set as a percentage.
Speed agree detection Effective when "Frequency
width (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
Spd Agree Width
output.
Sets the frequency detection
width as a percentage.
Speed agree detection Effective when "Desired fre-
level (+/-) quency (speed) agree 2," "Fre-
quency (FOUT) detection 3,"
or "Frequency (FOUT) detec-
tion 4" is set for a multi-func-
Spd Agree Lvl+-
tion output.
Frequency detection width is
set as a percentage.
Speed agree detection Effective when "Frequency
width (+/-) (speed) agree 2," "Desired fre-
quency (speed) agree 2," Fre-
quency (FOUT) detection 3 or
"Frequency detection 4" is set
Spd Agree Width+-
for a multi-function output.
Frequency detection width is
set as a percentage.
Operation when 0: Stop (Operation follows the
frequency reference is frequency reference.)
missing 1: Operation at 80% speed
continues. (At 80% of speed
before the frequency
reference was lost)
Ref Loss Sel
Frequency reference is lost:
Frequency reference dropped
over 90% in 400 ms.
