P21.11 FDT1 lower bound
P21.12 FDT2 upper bound
P21.13 FDT2 lower bound
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 P21.10 to be larger to some certain extent than P21.11, avoiding
status change frequently. See Fig. 5-18:

frequency attained
This parameter should be set with digital output terminal "frequency attained". When the
difference between output frequency and command frequency is less than this value, terminal
"frequency attained" aoutputs ON. See Fig. 5-19:
