[Appendix 2] Introduction to Renewal Tool
(3) For simultaneous replacement
The parameters shown below are a minimum number of parameters that need to be set for simultaneous
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.
Parameter

Changing required.
PA01 Control mode
PA04 Function selection A-1
PA09 Auto Tuning Response
PA06 Electronic gear numerator (CMX)
(Command input pulse

PA07 Electronic gear denominator (CDV)
(Commanded pulse multiplication

PD01 Input signal automatic on selection
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".
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)".
8 Auto tuning response setting
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-_A_
Servo Amplifier Instruction Manual.
8 When using an electronic gear, it is necessary to change the setting value.
(Note 1)
Set the same value as [Pr. 3] or [Pr. 4] of for the MR-J2S-_A_ servo amplifier.

(Note 1)
3001h J2S electronic gear setting value compatibility mode
Magnify the electronic gear setting value by 32 times.
3200 In-position range
(Note 2) Used to set an in-position range per command pulse unit.
Set the value of [Pr. 6] for the MR-J2S-_CP servo amplifier in this parameter as
well.
128 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) Used to set the encoder pulses output by the servo amplifier.
The setting value at left is according to the dividing ratio setting.
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).
