BFR is base frequency. It says whether motor is primarily designed for operation at 50Hz network or if its rated data are dedicated for 60Hz network. Very often the motor plate includes both data, for 50Hz and for 60Hz so you can choose BFR=50Hz or 60Hz.
FR affects some parameters, like max frequency, power in W or HP, etc.
In case with ATV12...M2 and using 3-phase 220V 100Hz motor it is easy:
Use BFR=50Hz and then enter motor data for 100Hz (set npr [motor nominal power], set Uns=220V, set ncr [motor nominal current], set Frs=100Hz, set nsp [motor nominal speed], set tfr>=100Hz).
Apply autotuning and continue configuring the rest parameters according to your application (speed range LSP, HSP, acceleration and deceleration ramps ACC, DEC, and so on)
