Functions
Regenerative Braking Function
• With the built-in regenerative braking circuit, this function allows an external braking resistor to
consume the motor's regeneration energy as heat.
This function is useful for a system in which the motor works as a generator when it is rapidly
decelerated.
• To use this function, configure the following settings.
* The regenerative braking function ON level conforms to the voltage setting for the Inverter's internal converter
(DC unit).
• When using the regenerative braking function, mount the optional braking resistor between
terminals P/+2 and RB, in addition to the settings above.
* The above usage rate of the regenerative braking function is the figure for using the optional braking resistor
(3G3AX-RBA, RBB, RBC).
• When using an external regenerative braking unit, set the usage rate of the regenerative braking
function to 0.0% (b090: 0.0) or disable the regenerative braking function selection (b095: 00). Do
not mount the braking resistor between terminals P/+2 and RB.

01 to 100.0:
A BRD usage rate for 100 seconds can be set, in
increments of 0.1%.
If the set usage rate is exceeded, a braking resistor
overload trip (E06) occurs.
