(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 .

Changing required.
PC22 Function selection C-1 _ 1 _ _ h _ 0 _ _ h Serial encoder selection.
This setting is for communication with the encoder of MR-J4. An incorrect setting
causes encoder initial communication data error 1 (AL.20.1).
PA21 Electronic gear selection 0001h 3001h J2S electronic gear setting value compatibility mode
* 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.
PA10 In-position range 100 3200 Set the range of droop pulses occurred when outputting a positioning completion
signal (INP).
Set the value as magnified by 32 times of the parameter No. 6 for the MR-J2S-
_CP_ servo amplifier.
PA15 Encoder output pulses 4
(Note 3)
128 Used to set the encoder pulses (A-phase and B-phase) output by the servo amplifier.
An output pulse is required to be set.
PC19 Encoder output pulse
setting selection
0 _ 1 _ h
(Note 3)
1 _ 1 _ h Encoder output pulse setting selection
Used to set the encoder pulses output by the servo amplifier.
The setting value at left is according to the dividing ratio setting.
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".
