5.2.1 Drive unit comparison of parameter details

(1) General-Purpose 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-_A_(-RJ). Refer to "Part 2: section 3.5".
MR-J3-DU_A_
No. Name and function
PA02 Regenerative option
Set this parameter when using the regenerative option,
brake unit, power regenerative converter, or power
regenerative 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 converter unit, set
this value regardless of whether or not the
regenerative option and brake unit are used.)
POINT
Manufacturer setting parameters are not described here.
Set a value to each "x" in the "Setting digit" columns.
An incorrect setting may cause the regenerative option to burn out.
When a regenerative option that is not available to use on a servo amplifier is
selected, a [AL.37 parameter error] occurs.
For a drive unit of 30 kW or more, be sure to set this parameter to "_ _ 0 0" since
selecting the regenerative option and brake unit is carried out by [Pr. PA01] of the
MR-J3-CR55K(4) converter unit.
