Timing for parameter to update

Timing for parameter to update

All data used by the driver is 32-bit wide.
Parameters are stored in RAM or non-volatile memory. The parameters in the RAM are erased once the control power
supply is shut off, but the parameters in the non-volatile memory are remained to store even if the control power
supply is shut off.
When the control 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.
Parameters having set using the parameter ID are stored 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.
When a parameter is changed, the timing to update the new value varies depending on the parameter. Check on
"Notation rules."
Parameters having set using the parameter ID are stored in the RAM. When updating the setting by
turning on the control power supply again, be sure to save the parameter in the non-volatile memory
before turning off the control power supply. If the control power supply is turned off before the data
is stored in the non-volatile memory, the parameter is not updated.
The non-volatile memory can be rewritten approximately 100,000 times.

Description
Recalculation and setup are immediately executed when the
parameter is written.
Recalculation and setup are executed when the operation is
stopped.
Recalculation and setup are executed after configuration is
executed or the control power supply is turned on again.
Recalculation and setup are executed after the control power
supply is turned on again.
