6-10-8 Frequency Detection

• The 3G3MV has the following frequency detection functions.
Frequency Detection:
Detects that the frequency reference coincides with the output frequency.
Frequency Detection Levels 1 and 2:
Detects that the output frequency is the same as or higher or lower than the set value (frequency
detection level) in n095.
• The multi-function outputs (n057 to n059) must be set for the frequency detection function.
H Frequency Detection
• The multi-function outputs (n057 to n059) must be set to the following in order to issue an output indi-
cating that the frequency reference and the output frequency agree.
Set value: 2 for frequency agree

• The parameters in n057 to n059 for multi-function output must be set for frequency detection output.
Set value: 4 for frequency detection level 1 (Output frequency y n095)
Set value: 5 for frequency detection level 2 (Output frequency x n095)
• Set the frequency detection level in n095.
