12.1 Timing for parameter to update
All data used by the driver is 32-bit wide. The register for the Modbus protocol is 16-bit wide, and one data is described
by two registers.
When a parameter is set via RS-485 communication, they are saved in the RAM. Parameters saved in the RAM is cleared
if the power supply is turned o. Parameters saved in the non-volatile memory are stored even after the power supply is
turned o.
When the power supply of the driver is turned on, the parameters stored in the non-volatile memory will be sent to the
RAM, and the recalculation and setup for the parameters will be executed in the RAM.
To save the parameters stored in the RAM to the non-volatile memory, execute the "Write batch NV memory" of the
maintenance command.
Parameters having set with the
MEXE02
are saved in the non-volatile memory if "data writing" is performed.
When a parameter is changed, the timing to update the new value varies depending on the parameter. See the
following four types.
•
Update immediately ................................................Recalculation and setup are immediately executed when the parameter
is written.
•
Update after operation stop .................................Recalculation and setup are executed when the operation is stopped.
•
Update after executing conguration .............. Recalculation and setup are executed after conguration is executed.
•
Update after turning on the power again ....... Recalculation and setup are executed after the power supply is turned
on again.
•
Parameters set via RS-485 communication are saved in the RAM. When changing a parameter that requires to turn
on the power supply again to update data, be sure to save it in the non-volatile memory before turning o the
power supply.
•
The non-volatile memory can be rewritten approximately 100,000 times.

Notation rules
In this part, each update timing is represented in an alphabet.
A: Update immediately
B: Update after operation stop
C: Update after executing Conguration or turning on the power again
D: Update after turning on the power again
READ/WRITE may be represented as "R/W" in this part.
