HANYOUNG NUX ML-D Series - Warning Occurrence and Handling

47
Before staring Installation Operation Specifications
●Execute all parameter save (PARA_COPY)
When parameter is not saved by RS485 communication, with this function, all parameters can be saved
by setting PARA_SAVE to “1”. When parameters such as set value (SV) change frequently, this is used
to increase memory lifespan by saving parameter at desired time after setting PARA_SAVE to “1”, in
order to prevent shortening lifespan of memory, where parameters are saved
Depending on warning occurrence type, process value (PV) and Manipulated Value (MV) are
processed as follows.
