(2) For secondary replacement
The parameters shown in this section are a minimum number of parameters that need to be set for
secondary 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. Setting example at primary replacement.
2. The value is for when the electronic gear setting of an existing servo motor (encoder resolution: 131072 pulses/rev) is "8/1".
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".

This setting is for communication with the encoder of MR-J4. An incorrect setting
causes encoder initial communication data error 1 (AL.20.1).

* For [Pr. PA06] or [Pr. PA07], the value when performing the primary
replacement is required to be maintained.
Magnify the electronic gear setting value by 32 times.

signal (INP).
Set the value as magnified by 32 times of the parameter No. 6 for the MR-J2S-
_CP_ servo amplifier.

(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.
