7.5 Regenerative option
CAUTION
Do not use the converter unit and drive unit with the regenerative options other
than the combinations specified below. Otherwise, it may cause a fire.
7.5.1 Combination and regenerative power
(1) MR-J3 series
The regenerative power values in the table are the regenerative power of the resistor and are not the
rated power.

Note 1. The composite resistor value of three options is 1.3 Ω . The resistor value of one option is 4 Ω .
2. The composite resistor value of three options is 5 Ω . The resistor value of one option is 15 Ω .
(2) MR-J4 series
The regenerative power values in the table are the regenerative power of the resistor and are not the
rated power.
The combinations of the regenerative option which differ from those for the J3 series are shown with the
gray background.
