Part 5: Review on Replacement of MR-J3-DU_ with MR-J4-DU_
5.2 Drive unit
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 resistance
regeneration 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.
