PD09
Note. For items that have no setting value listed in the table, refer to "Part 3: Review on Replacement of MR-J2S-_B_ with MR-J4-_B_".
POINT
The conversion rules in the above table give due consideration to compatibility.
However, the servo parameter system of MR-J2S-_B_ and that of MR-J4-_B_
are so different that the rules may not sufficiently apply to cases of special
operation (including special specifications). Change the settings as necessary in
such cases.
[Pr. PA19 Parameter writing inhibit] after parameter conversion is the initial
value.
• MR-J4-_B_: [Pr. PA19] = "00ABh"
When using analog monitor output, perform an operation check because MR-
J2S-_B_ and MR-J4-_B_ have different output voltage specifications for droop
pulses.
• MR-J4-_B_: [Pr. PC09]/[Pr. PC10]
Output signal assignments will be initialized. Change the settings as necessary.
• MR-J4-_B_ : [Pr. PD07] to [Pr. PD09]
Various offset parameters cannot be converted. Change the settings as
necessary.
• MR-J4-_B_: [Pr. PC11], [Pr. PC12]
The conversion rules apply only to the common parameters of MR-J2S-_B_ and
MR-J4-_B_.
Additional parameters of MR-J4-_B_ are set to the initial values of MR-J4-_B_.
The setting value of the error excessive alarm level is 2. Change the settings as
necessary.
• MR-J4-_B_: [Pr. PC01 Error excessive alarm level]
The parameter conversion rules are intended for the replacement of "HC-
_FS/HA-_FS motors" with "HG motors". When using "HC-_FS/HA-_FS motors"
without being replaced, check and change the "electronic gear setting" and
"pulse output".(Refer to (2) in Section 2.4.3 and 4. HC-_FS/HA-_FS MOTOR
DRIVE.)

To configure the same settings as those for MR-J2S-_B_,
select "Forced stop deceleration function disabled (EM1)".
Auto tuning response setting
-
Adjust the gain value again after the replacement.
When the encoder output pulse setting is a dividing ratio
setting, this must be adjusted to match the number of pulses
per servo motor rotation.
As the parameter converter function converts the setting
-
value into 131072 [pulses] for the MR-J2S-_B_ and
4194304 [pulses] for the MR-J4-_B_, restore the setting
value to the value for the MR-J2S-_B_ when replacing the
servo amplifier.
- Set the value as required.
- Set the value as required.
This parameter is not converted by the parameter converter

function. Set the parameters as required.
