Question
I changed the set value of Inverter parameter number n01 to 9 (3-wire sequence), as described in the manual, but the setting changed to 1. Why did it change?
Answer
A setting of 9 causes the Inverter to be initialized in 3-wire sequence mode. When the setting is changed to 9 and the Return Key is pressed, the Inverter is immediately initialized. At this point, the n01 setting is also initialized and reverts to its default setting of 1.
The same phenomenon occurs if the setting is changed to 8.
It is normal for n01 to revert to a setting of 1 after initialization.
