[FDT-1]
When the output frequency reaches the reference
frequency (target frequency), AX-CX terminal is
CLOSED.
Detecting Condition: Value (Ref. Freq-Output Freq)<=
Freq Detection Bandwidth (I/O-75)/2
[AX-CX configured as ‘FDT-1’]
*AX: A1~A4, CX: C1~C4
[FDT-2]
AX-CX is CLOSED when the reference frequency is
in I/O-75 [FDT Bandwidth] centered on I/O-74 [FDT
Frequency], and the output frequency reaches I/O-75
centered on I/O-74.
Detecting Condition: FDT-1 condition & (Value
(Output Freq- Freq Detection)<= Freq Detection
Bandwidth (I/O-75)/2)
[AX-CX configured as ‘FDT-2’]
[FDT-3]
AX-CX is CLOSED when the output frequency
reaches the band centered on the FDT frequency. The
output is OPENED when the output frequency goes
outside the FDT bandwidth centered on the FDT
frequency.
Detecting Condition: Value (Freq Detection (I/O-74)-
Output Freq)<= Freq Detection Bandwidth (I/O-75)/2
