2.2.5 Conversion rules (MR-J3-_A_ => MR-J4-_A_)
The following table shows the servo parameter conversion rules from MR-J3-_A_ to MR-J4- _B_.
Servo parameters not specified in the following table will be set to the initial values.

PA08 Auto tuning mode
PA09 Auto tuning response
PA10 In-position range
PA11 Forward rotation torque limit
PA12 Reverse rotation torque limit
PA13 Command pulse input form

POINT
Because the servo parameters of MR-J3-_A _ and those of MR-J4-_A_ are not
completely interchangeable, the conversion rules may not be applied. Check the
operations and review the settings as necessary.
The value of the parameter writing after parameter conversion is the initial value.
• MR-J4-_A_: [Pr. PA19] = "00AAh"
Various offset parameters cannot be converted. Change the settings as
necessary.
• MR-J4-_A_: [Pr. PC37] to [Pr. PC40]
The following parameters of MR-J4-_A_ are compatible with the servo amplifier's
software version A3 or later. The software version can be checked in the
system configuration.
• MR-J4-_A_: [Pr. PA03 Absolute position detection system "_ _ _2h" (Absolute
position detection system by communication)]
• MR-J4-_A_: [Pr. PC21 RS-422 communication function selection]
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_: [Pr. PA05] to [Pr. PA07]
