APPENDIX
App. 5.14.2 Auxiliary function
(1) Reading/writing parameters
For the usage of the parameter read/write, which is the same as that of the servo amplifier
MR-J4(W
)- B, refer to Section 7.1.
However, servo parameters No.0100 to 01FF are used.
When the parameter error (servo alarm 37) has occurred at system startup, check the parameter No. on
which the error has occurred in the servo parameter error number (monitor No.0500 to 0510). Then reboot
software, set correct parameters, and restart the system.
POINT
When SSCNET communication method is SSCNET , servo parameters No.
1100 to 1380 of MR-J4(W
)- B cannot be written while system is running.
Parameter number error (PWENn (n
1 to 2)) turns on.
When SSCNET communication method is SSCNET /H, servo parameters
No. 0100 to 01FF of MR-J3(W)-
B cannot be written while system is
running. Parameter number error (PWENn (n
1 to 2)) turns on.
When SSCNET communication method is SSCNET , servo parameters No.
1100 to 1380 of MR-J4(W
)- B cannot be read while system is running.
Parameter number error PRENn (n
1 to 2)) turns on.
When SSCNET communication method is SSCNET /H, servo parameters
No. 0100 to 01FF of MR-J3(W)-
B cannot be read while system is running.
Parameter number error PRENn (n
1 to 2)) turns on.
(2) Changing parameters at the servo
For how to check parameter changes at the servo, which is the same as that of the servo amplifier
MR-J4(W
)- B, refer to Section 7.2.
However, to check changed servo parameter numbers, use servo parameter change number (monitor
No.0580 to 058F) corresponding to the servo parameter change number 01 (PSN01) of the servo
parameter change number table.
POINT
The reasons that parameters are re-written on the servo amplifier are as
follows.
When parameters are changed using MR Configurator2 (This includes
execution of the machine analyzer and the gain search function.)
The parameter was automatically changed such as by the real time auto
tuning function.
Refer to the Servo Amplifier Instruction Manual on your servo amplifier
concerning servo parameters that are automatically changed.
