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.
