Store New Register Data (ENTER command) 
After being written in a selected holding register by the Write in Holding Register 
command (06h) or in selected holding registers by the Write in Holding Registers 
command (10h), new data is temporary and still outside the storage element of the 
inverter. If power to the inverter is shut off, this new data is lost and the previous data 
returns. The ENTER command is used to store this new data in the storage element of 
the inverter. Follow the instructions below to submit the ENTER command. 
Submitting an ENTER Command:
• Write any data in all memory (of a holding register at 0900h) by the Write in Holding 
Register command [06h].
NOTE: The ENTER command takes much time to run. You can check its progress by 
monitoring the Data Writing signal (of a coil at 001Ah).
NOTE: The service life of the storage element of the inverter is limited (to about 
100,000 write operations). Frequent use of the ENTER command may shorten its service 
life.
