5 - 10 EtherCAT Communication Unit USER’S MANUAL (I574-E1)
All savable parameters are saved in the Inverter EEPROM.
Saving is executed only when a specific value is written to sub-index 1. This prevents parameter val-
ues from being accidentally overwritten.
The specific value means “save”.
A value of 00000001 hex (command valid) is given when reading.
Parameters cannot be saved to the EEPROM during inverter operation.
In the following cases, an ABORT code is returned.
Writing with CompleteAccess.
Writing a value other than 65766173 hex.
Writing to the EEPROM may take up to 1 second. (This is when all objects are changed.)
There is a limit to the number of times you can write to the EEPROM. For the life (number of writes)
of the EEPROM, refer to the user's manual for the MX2-series or RX-V1-series Inverters.
Inverter parameters are reset to their default settings.
A restoration operation is executed only when a specific value is written to sub-index 1. This prevents
parameter values from being accidentally overwritten.
The specific value means “load.”
A value of 00000001 hex (command valid) is given when reading.
In the following cases, an ABORT code is returned.
Writing with CompleteAccess.
Writing a value other than 64616F6C hex.
Writing to the EEPROM may take up to 3 seconds. (This is when all objects are changed.)
There is a limit to the number of times you can write to the EEPROM. For the life (number of writes)
of the EEPROM, refer to the user's manual for the MX2-series or RX-V1-series Inverters.
