(1) For primary replacement
The parameters shown below are a minimum number of parameters that need to be set for primary
replacement. Depending on the settings of the currently used servo amplifier, parameters other than
these may need to be set. For details, refer to Part 4 Section 3.6.

Note 1. The example value shown is for when the electronic gear setting of an existing servo amplifier is set as "8/1".
2. The example value shown is for when the in-position range of an existing servo amplifier is set as "100".
3. The example value shown is for when the output pulse setting of an existing HC-KFS motor (encoder resolution: 131072
pulses/rev) is "Dividing ratio: 1/4".
POINT
When the MR-J4-_B-RJ020 servo amplifier is combined with the MR-J4-T20
SSCNET conversion unit, the servo amplifier is recognized as MR-J2S by the
controller. For parameters, changes to the program or the parameters are
required as necessary.
(For details, refer to "[Appendix 1] Summary of MR-J4_B_-RJ020 + MR-J4-T20"
in this document.)
For details on how to set parameters, refer to Chapter 5 of the "MR-J4-_B_-
RJ020 Servo Amplifier Instruction Manual (SH(NA)030124)".
Setting value
_ _ _ 6h Select the servo amplifier control mode.
Select the positioning mode (point table method).
0000h Forced stop deceleration function selection
To configure the same settings as those for MR-J2S, select "Forced stop
deceleration function disabled (EM1)".
_ 1 _ _ h Serial encoder selection.
This setting is for communication with the encoder of MR-J2S. An incorrect setting
causes encoder initial communication data error 1 (AL.20.1).
8
Auto tuning response setting
8 When using an electronic gear, it is necessary to change the setting value.
(Note 1) Set the same value as [Pr. 4] and [Pr. 5] of for the MR-J2S-_CP_ servo
amplifier.
1
(Note 1)
0001h A setting value for the electronic gear [Pr. PA06] or [Pr. PA07] becomes effective.
100 In-position range
(Note 2) Used to set an in-position range per command pulse unit.
Set the same value as [Pr. 6] of for the MR-J2S-_CP_ servo amplifier.
4 Used to set the encoder pulses (A-phase and B-phase) output by the servo amplifier.
(Note 3)
0 _ 1 _ h Encoder output pulse setting selection
(Note 3)
1_ _ _h When the EMG signal of the existing MR-J2S-CP servo amplifier has not been
assigned, enable automatic on of the forced stop signal after replacement.
An incorrect setting causes Servo forced stop warning (AL. E6.1).
- When the assignment of the Input/output signal for the existing MR-J2S servo
amplifier, setting is required.
For details, refer to Part 4 Section 3.6.
Appendix 2-87
When replacing, switch the power on after setting the parameter value to "8".
* It is necessary to make gain adjustment again when replacing. The setting
value of this parameter is equivalent to the slow response of the MR-J2S. Perform
adjustment since tha gain can be too low for the slow response.
For details on how to make gain adjustments, refer to Chapter 6 of the MR-J4
Servo Amplifier Instruction Manual.
Used to set the encoder pulses output by the servo amplifier. The setting value at
left is according to the dividing ratio setting.
