2.3.5 Conversion rules

POINT
The conversion rules in this section give due consideration to compatibility.
However, the servo parameter system of MR-J2S-_A_/ MR-J2S-_CP_/MR-J2S-
_CL_ and that of MR-J4-_A_ 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.
The value of [Pr. PA19 Parameter writing inhibit] after parameter conversion is
the initial value.
• MR-J4-_A_: [Pr. PA19] = "00AAh"
When using analog monitor output, perform an operation check because MR-
J2S-_A_/MR-J2S-_CP_/MR-J2S-_CL_ and MR-J4-_A_ have different output
voltage specifications for droop pulses.
• MR-J4-_A_: [Pr. PC14]/[Pr. PC15]
Various offset parameters cannot be converted. Change the settings as
necessary.
• MR-J4-_A_: [Pr. PC37] to [Pr. PC40]
When the renewal tool is not used, set the conversion of I/O signal assignment
with the parameter converter function to "Disabled". Change the settings or
wiring as necessary because the parameters related to I/O signal assignment
are not converted.
When the renewal tool is used, set the conversion of I/O signal assignment with
the parameter converter function to "Enabled". According to the control signal
connection of the renewal tool, the parameters related to I/O signal assignment
are converted. (For details, refer to section 2.3.5 (1).)
• MR-J4-_A_: [Pr. PD03] to [Pr. PD28]
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. PC21 RS-422 communication function selection]
The conversion rules apply only to the common parameters of MR-J2S-_A_/MR-
J2S-_CP_/MR-J2S-_CL_ and MR-J4-_A_(-RJ).
Additional parameters of MR-J4-_A_(-RJ) are set to the initial values of MR-J4-
_A_(-RJ).
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 (5) in Section 2.3.5 and 4. HC-_FS/HA-_FS MOTOR
DRIVE.)
