Conversion Rules (Mr-J3-_T_(Dio Command/ Serial Communication Operation) => Mr-J4 - Mitsubishi Electric MELSERVO-J4 Series Transition Handbook

2.2.7 Conversion rules (MR-J3-_T_(DIO Command/ Serial communication operation) => MR-J4-_A_-RJ)
The following table shows the servo parameter conversion rules from MR-J3-_T_(DIO Command/ Serial
communication operation) to MR-J4- _A_-RJ.
Servo parameters not specified in the following table will be set to the initial values.
POINT
This parameter can be set when MR-J4-_A_-RJ with software version A3 or
later is used for the conversion from MR-J3-_T_. The software version can be
checked in the system configuration of MR Configurator 2.
The setting value of "parameter writing inhibit" after the conversion from MR-J3-
_T_ is as follows:
MR-J4-_A_-RJ: [Pr. PA19] = "00ABh "
Various offset parameters cannot be converted. Change the settings as
necessary.
MR-J4-_A_-RJ: [Pr. Po15]/[Pr. Po16]/[Pr. Po21]/[Pr. Po22]
Servo motor series can be selected in MR Configurator2 with software version
1.72A or later.
Because the servo parameters of MR-J3-_T _ and those of MR-J4-_A_-RJ are
not completely interchangeable, the conversion rules may not be applied. Check
the operations and review the settings as necessary.
When the renewal tool is not used, disable conversion of the input/output signal
assignment (parameter converter function). The parameters related to the
input/output signal assignment are not converted. Review wiring and settings as
necessary.
When the renewal tool is used, enable conversion of the input/output signal
assignment (parameter converter function). The parameters related to the
input/output signal assignment are converted according to the control signal
connection of the renewal tool.
MR-J4-_A_-RJ: [Pr. PD03] ～ [Pr. PD28]
The parameter converter function converts the parameters related to the
input/output signal assignment of the MR-D01 extension I/O unit regardless of
whether the assignment conversion (parameter converter function) is enabled or
disabled.
MR-J4-_A_-RJ: [Pr. Po02] ～ [Pr. Po09]
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.
MR-J4-_A_-RJ: [Pr. PA06] ～ [Pr. PA07]
The following parameters will be converted to values according to the encoder
resolution of the servo motor.
MR-J4-_A_-RJ: [Pr. PA10]/[Pr. PA15]/[Pr. PA21]/[Pr. PC14]
When "HG series" is selected for servo motor series, the parameters will be
converted to values according to the encoder resolution of the HG motor.
When "HF-_P/HC-_P/HA-_P series" is selected for servo motor series, the
parameters will be converted to values according to the encoder resolution of
the HF-_P/HC-_P/HA-_P servo motor.
