Regenerative option selection

If the generated regenerative power is too large and the regenerative capacity of the built-in regenerative resistor of the servo
amplifier is insufficient, use the regenerative option to improve the regenerative capacity and consume the generated
regenerative power. Set [Pr. PA02.0-1 Regenerative option selection] in accordance with the regenerative resistor in use.
Refer to "Regenerative option" in the following manual for the details of the regenerative options.
MR-J5 User's Manual (Hardware)

Regenerative option

For the regenerative options, select the Mitsubishi Electric-specified regenerative resistor (MR-RB series).
• The regenerative option cannot be used with the MR-J5D_-_G_.
Precautions
• To prevent a fire from occurring, use servo amplifiers with regenerative options in the specified combinations.

Outline
Select a regenerative option to be used.
Incorrect setting may cause the regenerative option to burn.
If a selected regenerative option is not for use with the servo amplifier,
[AL. 037 Parameter error] occurs.
Other regenerative options cannot be used together with the FR-XC-
(H).
The setting value of this servo parameter is disabled for the MR-J5D_-
_G_.
00: Regenerative option is not used.
• No regenerative resistors are used on servo amplifiers with a
capacity of 100 W.
• Built-in regenerative resistors are used on servo amplifiers with a
capacity of 0.2 kW to 7 kW.
