7. AUXILIARY FUNCTION
Note 1. The flash ROM parameter backup function becomes available after the system preparation completion
(system status code: 0001h).
2. When the flash ROM transfer preparation error (FRNG) or the flash ROM transfer error (FSNG) occurs, check the procedure
and restart the process from the beginning.
3. Do not turn off the power supply of the position board during the parameter backup in the flash ROM. If flash ROM parameter
read is executed before normal backup completion, flash ROM parameter read error (system status code: 0005h) occurs. In
this case, execute parameter initialization (system command code: 0003h), set parameters as required and backup data to
flash ROM again.
4. When flash ROM parameter read is executed, the value of gain of the servo amplifier is the backed up value in the flash ROM,
so vibration or abnormal sound may occur even when auto tuning is valid. Execute flash ROM backup after adjusting the gain
of the servo amplifier.
5. Execute flash ROM backup after home position return is performed when the absolute position detection system is used.
6. Execute Note 5 above when changing a servo motor.
7. Execute flash ROM backup after changing a position board.
8. The flash ROM can be rewritten up to 100,000 times. If it exceeds 100,000 times, number of write accesses to flash ROM error
(system alarm 36, detail 01) occurs and parameter backup will not be performed.
9. The flash ROM can be rewritten up to 25 times after every system preparation completion. If it exceeds 25 times, number of
write accesses to flash ROM error (system alarm 36, detail 03) occurs and parameter backup will not be performed. Rewriting
times to the flash ROM is cleared to 0 by resetting the system alarm or the software reboot. The parameter backup times
executed after system preparation completion can be checked in the parameter backup times (system monitor No.040A).
10. Perform the parameter backup while the operation of all axes is stopped.
11. Writing and reading parameters are impossible during the flash ROM transfer.
