2.3.3 Conversion rules (MR-J3-_B_ and MR-J3W-_B => MR-J4-_B_ and MR-J4W2-_B)
(1) Conversion rules (MR-J3-_B_ (standard) and MR-J3W-_B (standard) => MR-J4-_B_ (standard) and
MR-J4W2-_B (standard))
The following table shows the servo parameter conversion rules from MR-J3-_B_ (standard) and MR-
J3W-_B (standard) to MR-J4- _B_ (standard) and MR-J4W2-_B (standard).
Servo parameters not specified in the following table will be set to the initial values.
POINT
Because the servo parameters of MR-J3-_B_/MR-J3W-_B and those of MR-J4-
_B_/MR-J4W2-_B are not completely interchangeable, the conversion rules may
not be applied. Check the operations and review the settings as necessary.
The parameter writing inhibit after parameter conversion is the initial value (the
following setting value).
• MR-J4-_B_ and MR-J3W-_B: [Pr. PA19 Parameter writing inhibit] = "00ABh"
Various offset parameters cannot be converted. Change the settings as
necessary.
• MR-J4-_B_ and MR-J3W-_B: [Pr. PC11]/[Pr. PC12]
When the geared servo motor is replaced, the reduction ratio may differ before
and after the replacement. Check the specifications of the servo motor and
review the electronic gear settings as necessary. For the electronic gear
settings, refer to the controller instruction manual.
Some parameters are not supported depending on the software version of the
servo amplifier. Refer to section 2.3.4 for details.
Refer to section 2.3.4 (2) for differences between the servo parameters of MR-
J3-_B_ and MR-J3W-_B.

The setting value will increase by 16
times when it is 4095 or smaller.
The setting value other than the above
will be 65535.

When the setting value of PC03 is
_ _ 1_, the setting value of PA15 is
increased by 16 times.
However, when the value is 65535 or
larger, the setting value will be
65535.
When the setting value of PC03 is
other than _ _1_, it will be
maintained.
