（３）In the Case of Package Replacement
* Listed below in the table are the parameters you, at least, need to set up when performing a package replacement.
You may need to set up parameters other than the parameters listed below depending on the setting of the existing
amplifier. For the details, see "Guide for Replacing MR-J2S/J2M Series with J4 Series L(NA)03093", Part 2,
Section 3.5.
Parameter No. Setting Item Setting Description
*Required
PA04 Function selection A-1 0000h Selection of forced stop/deceleration function
To make the same setting as MR-J2S, select "Forced stop/deceleration function not valid
(EM1 is used)."
PA09 Automatic tuning response 8
Automatic tuning response setting
After replacement, set "8" to this setting. Turn on the system.
* After replacement, you need to readjust the gain. This setting is equivalent to the low
response of MR-J2S. The low response may make the gain too low. Make adjustment.
For the details of how to adjust gains, see Section 6 in the technical materials on servo
amplifiers (MR-J4A) issued by Mitsubishi Electric Corporation.

* For 11kW or higher only when
this function is used
0006h
Selection of dynamic brake interlock (DB)
If you use this function with MR-J2S of 11kW or higher, set up this parameter. DB
signals are assigned to the CN1-48 pins.
*For position control mode only
PA06 Electronic gear numerator (CMX)
(Numerator of the increment of the
command input pulse) 256
(Note 1)
PA07 Electronic gear denominator (CDV)
(Denominator of the increment of
the command input pulse) 1
(Note 1)
If you use an electronic gear, you need to change the setting.
If you perform a package replacement, follow the equation below to calculate the setting:

* If the motor is equipped with a decelerator, the actual gear ratios of the motors before
and after replacement may be different. If the actual gear ratios are different, consider
the actual gear ratio to make the setting.
PA13 Input form of command pulse □2□□h Selection of pulse row filter
The setting shown in the left-side column is a filter setting of the command pulse row that
is equivalent to that with MR-J2S-_A (when the differential line driver type is set).
* Make sure to set up the filter. Otherwise, positioning may be incorrect.
In addition, you need to make the logic of the command pulse correspond to the positioning
module. For the details, see section 2.6.5.
* If you do not set up the logic, the motor will not turn. Make sure to make the setting.
PA10 In-position range 3200
(Note 2)
Specify the range of the accumulated pulse to output the positioning-completed signal (INP).
Multiply the value of parameter No. 5 of the MR-J2S-_A servo amplifier by 32, and specify
this value.
*For speed control mode only
PA01 Control mode □□□2h Select the control mode of the servo amplifier. The speed control mode is set.
PC12 Maximum rotational speed of analog
speed command 3000 Maximum rotational speed of analog speed command
The setting in the left-side column is of the case where the HC-SFS53 motor is replaced
by the HG-SR52 motor.
*For torque control mode only
PA01 Control mode □□□4h Specify the control mode of the servo amplifier.
The torque control mode is set.
PC12 Maximum rotational speed of analog
speed limit 3000 Maximum rotational seed of analog speed limit
The setting in the left-side column is of the case where the HC-SFS53 motor is replaced
by the HG-SR52 motor.
PC13 Maximum output of analog torque
command 100 Maximum output of analog torque command
Specify the same value as the MR-J2S-_A servo amplifier.
*When encoder output pulses are used
PA15 Encoder output pulse 128
（Note 3）
Select the encoder pulse (phase A or phase B) output from the servo amplifier.
PC19 Selection of encoder output pulse
setting 0□1□h
(Note 3)
Selection of encoder output pulse setting
Set up the encoder pulse output from the servo amplifier. The setting shown in the left-side
column is a setting of a division ratio.
Note 1 This is an example of the case where the electronic gear of the existing servo amplifier is set to "8/1".
Note 2 This is an example of the case where the in-position range of the existing servo amplifier is set to "100".
Note 3 This is an example of the case where the output pulse setting of the existing HC-KFS motor (with the encoder resolution of 131072 pulse/rev) is "Division
ratio: 1/4".
