Chapter 6 - Parameter Description
6-28
For example: if I/O-71 is set to 50%, the maximum
analog output will be 5VDC at maximum output
frequency.
[Current]
S0 or S1 output provides 0-10VDC signal
corresponding to VFD output current from 0A to
VFD current rating.
[Voltage]
S0 or S1 output provides 0-10VDC signal
corresponding to VFD output voltage from 0V to
Maximum Voltage.
[kW]
S0 or S1 output provides 0-10VDC signal
corresponding to VFD output kW from 0kW to
Maximum VFD kW output rating.
[Ext.PID Out]
S0 or S1 output provides 0-10VDC signal
corresponding to VFD External PID output from 0
to 100%.

The FDT function allows VFD to activate AUX
relay set to FDT at predetermined frequency by
FDT-1, 2, 3 or 4 modes. Refer to I/O-76~79 for
detailed description.

[FDT-1]
If any AUX relay is set to FDT-1 and VFD
accelerates or decelerates, the AUX relay will be
closed and stay closed only if difference between
speed reference and output frequency is less than
[I/O-75]/2.
[FDT-2]
If any AUX relay is set to FDT-2 and VFD
accelerates or decelerates, the AUX relay will be
closed while the speed reference and output
frequency are within I/O-75 centered on I/O-74.
[FDT-3]
The selected AUX relay will be closed when the
output frequency during acceleration or
deceleration is within I/O-75 FDT bandwidth
centered on I/O-74. If output frequency is outside
FDT bandwidth, AUX relay is open.
