Chapter 6 - Parameter Description [I/O]
6-52
[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
AX-CX configured as ‘FDT-3’
[FDT-4]
AX-CX is CLOSED when the output frequency
reaches the FDT frequency. The output is OPENED
when the output frequency goes below the FDT
bandwidth centered on the FDT frequency.
Detecting Condition:
During Accel: Output freq >= Freq Detection
During Decel: Output freq > (Freq Detection (I/O-74) -
Freq Detection Bandwidth (I/O-75)/2)
AX-CX configured as ‘FDT-4’
[FDT-5]
This is the inverted output of [FDT-4].
Detecting Condition:
During Accel: Output freq <= Freq Detection
During Decel: Output freq < (Freq Detection (I/O-74) -
Freq Detection Bandwidth (I/O-75)/2)
AX-CX configured as ‘FDT-5’
