Part 5: Review on Replacement of MR-J2S-30 kW or Higher Capacity Models with MR-J4-DU_
(c) General-purpose interface 400 V class
Here are described settings of drive unit specific parameters. Settings of the other parameters are the
same as MR-J4-_A_. Refer to Chapter 5 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual".
MR-J2S-_A4
No. Name and function
0 Control mode and regenerative option selection
0 0 0 0
Refer to the MR-J2S-_A_ servo amplifier
Instruction Manual.
Regenerative option selection
Make sure to set "0".

value
0 Servo motor speed (±8 V/max. speed)
1 Torque (±8/max. torque)
2 Servo motor speed (±8 V/max. speed)
3 Torque (±8/max. torque)
4 Current command (±8 V/max. current command)
5 Speed command (±8/max. speed)
6 Droop pulse (±10 V/128 pulse)
7 Droop pulse (±10 V/2048 pulse)
8 Droop pulse (±10 V/8192 pulse)
9 Droop pulse (±10 V/32768 pulse)
A Droop pulse (±10 V/131072 pulse)
B Bus voltage (+8 V/800 V)
Note 1. "Maximum speed" and " Maximum torque" differ depending on the servo motor. Therefore, after the existing motor has been
replaced with an HG motor, the output voltage for "Maximum speed" or " Maximum torque" may differ.
2. Units used for MR-J2S-_A_ are different from those for MR-J4-_A_. Note that the input range of existing equipment needs to
be adjusted.
3. Set "0008" or "0009". When setting the value, note that the input range of existing equipment needs to be adjusted.

POINT
Connecting to a servo system controller writes servo parameters of the controller
into the corresponding parameters of the drive unit.
There are some servo system controller models, drive unit software versions, or
MR Configurator2 software versions which limit setting of some parameters or
setting values of the parameters. For details, refer to servo system controller
user's manuals.
No.
PA02 Regenerative options
Select a regenerative option.
For a drive unit, select a regenerative option by
configuring the converter unit.
Select "_ _ 0 0" or "_ _ 0 1", otherwise [AL. 37 Parameter
error] will occur.
00: Use no regenerative option, or use a regenerative
option by configuring the converter unit.
