Usage Rate of Regen-
erative Braking
0.0: Regenerative braking not active
0.1 to 100.0 (Limited by b097) The usage rate must
be set as a percentage (%) as follows:
Allowable braking frequency [%] of the connected
braking resistor or lower.
Exceeding the set usage rate causes the protective
function to be activated, which results in a trip.

Braking Resistor Value
Minimum connection resistance to 600.0
Set the resistance of the braking resistor actually
connected to the inverter.
Then, the inverter automatically calculates the upper
limit value allowable in b090.
This allows you to consider only the allowable brak-
ing frequency (%) of the braking resistor when set-
ting b090.
