FDT1 output frequency is the set frequency after Accel/Decel.
1: Detected speed value
FDT1 output frequency is actually detected or identified frequency. If the drive is under V/f
pattern, it should be output frequency.
Tens place: FDT2 detected object
0: Set value of speed (frequency after Accel/Decel)
FDT2 output frequency is the set frequency after Accel/Decel.
1: Detected speed value
FDT2 output frequency is actually detected or identified frequency. If the drive is under V/f
pattern, it should be output frequency.
C1-10
FDT1 upper value
Range: 0.00Hz~maximum FREQ
Factory default:
50.00Hz
C1-11
FDT1 lower value
Range: 0.00Hz~ maximum FREQ
Factory default:
49.00Hz
C1-12
FDT2 upper value
Range: 0.00Hz~ maximum FREQ
Factory default:
25.00Hz
C1-13
FDT2 lower value
Range: 0.00Hz~ maximum FREQ
Factory default:
24.00Hz
These parameters should be set with digital output terminals "FDT1" and "FDT2". Take FDT1
for example, the drive outputs ON signal when output frequency exceeds upper value of FDT1
and will not output OFF signal unless output frequency drops to below lower value of FDT1.
Please set C1-10 to be larger to some certain extent than C1-11, avoiding status change
frequently. See Fig. 6-22:
FDT2 performance figure is the same as FDT1.
