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".
（２）In the Case of Secondary Replacement
* Listed below in the table are the parameters you, at least, need to set up when performing a secondary
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.

Note 1 This is an example of the setting at the time of a primary replacement.
Note 2 This is an example of the case where the electronic gear of the existing servo amplifier is set to "8/1" with the existing servomotor (with the encoder
resolution of 131072 pulse/rev).
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".

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.

□0□□h Selection of the serial encoder
Set up the communications with the encoder of MR-J4. If you do not make a
correct setting, the encoder causes an initial communication data error (AL
16.1).
256 If you use an electronic gear, you need to change the setting.
If you perform a secondary 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.
3200 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.
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.
3000 Maximum rotational speed 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.
128 Select the encoder pulse (phase A or phase B) output from the servo amplifier.
You need to set up the output pulse.

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.
