Emotron VSB Instruction Manual Chapter 6 Specification of Parameters
C1-09
Detected object of frequency
doubling technology(FDT)
Range: 00 - 11
Factory default:
00
 Unit's place: FDT1 detective object
0: Set value of speed (frequency after Accel/Decel)
FDT1 output frequency is the command 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.
 Decade: FDT2 detective object
0: Set value of speed (frequency after Accel/Decel)
FDT2 output frequency is the command 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 bound Range: 0.00Hz - maximum FREQ
Factory default:
50.00Hz
C1-11 FDT1 lower bound Range: 0.00Hz - maximum FREQ
Factory default:
49.00Hz
C1-12 FDT2 upper bound Range: 0.00Hz - maximum FREQ
Factory default:
25.00Hz
C1-13 FDT2 lower bound 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
bound of FDT1 and will not output OFF signal unless output frequency drops to below lower
bound of FDT1. Please set C1-10 to be larger to some certain extent than C1-11, avoiding
status change frequently. See Fig. 6-14:
