Part 5: Review on Replacement of MR-J3-DU_ with MR-J4-DU_
(2) SSCNET interface 200 V/400 V class
Here are described settings of drive unit specific parameters. Settings of the other parameters are
the same as MR-J4-_B_. Refer to "Part 3: section 3.6".
MR-J3-DU-_B_
No. Name and function
PA02 Regenerative option
Set this parameter when using the regenerative option,
brake unit, power regeneration converter, or power
regeneration common converter.
0 0 x x:
Selection of regenerative option
00: Regenerative option is not used, or when you use a
regenerative option, set the regenerative option with
the converter unit.
When using the drive unit with the resistance
regeneration converter unit, set this value regardless
of whether or not the regenerative option and brake
unit are used.)
POINT
When you connect the amplifier to a servo system controller, servo parameter
values of the servo system controller will be written to each parameter.
Setting may not be made to some parameters and their ranges depending on
the servo system controller model, drive unit software version, and MR
Configurator2 software version. For details, refer to the servo system controller
user's manual.

PA02 Regenerative option
Select a regenerative option.
For the drive unit, select the regenerative option with the

Selecting other than "_ _ 0 0" or "_ _ 0 1" will trigger [AL.
37 Parameter error].
_ _ x x:
Regenerative option selection
00: Regenerative option is not used, or when you use a
regenerative option, set the regenerative option with
the converter unit.
When using the drive unit with the resistance
regeneration converter unit, set this value regardless
of whether or not the regenerative option and brake
unit are used.)
_ x _ _:
Converter unit selection
0: MR-CR_
7: MR-CV_
Setting a value other than "0" or "7" will trigger [AL. 37].
x _ _ _:
Enable or disable the protection coordination mode.
0: Protection coordination mode enabled
4: Protection coordination mode disabled (stand-alone
drive)
Set "4" for the drive unit which is not connected to the
MR-CV_ with the protection coordination cable.
To disable the protection coordination mode, set
"Protection coordination mode function between
converter and drive unit selection" of [Pr. PF03] to
"Enabled (_ 1 _ _)", and then this parameter to
"Protection coordination mode disabled (4 _ _ _)".
