Fb-28
Current for disengaging the external brake. It shall be used with Fb-27, set
the current value when Fb-27=1, the current percentage is based on the rated current of
motor.

FC-16 Brake Duty Ratio
In dynamic brake, braking unit works in PWM mode. FC-16 is for setting the duty ratio of
braking unit. If the bigger value of FC-16 is, the stronger brake capacity would be. This
function is only applied to integrated braking unit.

FC-18 ones place=0 AVR disabled
Output voltage varies with the changes of input voltage or DC bus voltage.
FC-18 ones place=1 AVR enabled (Enabled all the time)
If input voltage< rated input voltage of inverter, and output frequency> corresponding
frequency to the voltage on V/F curve, inverter will output maximum voltage to make
motor work at maximum capacity. If input voltage > rated input voltage of inverter,
inverter will drop the output voltage and remains V/F proportion.
