1) Register Details
This register is used to request clearance of alarm history.
Normally, the contents of the alarm history register are automatically erased when switching from Remote Off to Remote On,
but by writing this register, it is also possible to erase the history.
・Use Case 1
By polling the operations of read "Alarm history register" and write "Alarm history erase
register", it is possible to acquire only new protection factors that occurred during polling.
・Use Case 2
It is a specification that the alarm history remains even when the protection function with automatic recovery setting operates.
When the current alarm history is unnecessary, this function can clear the alarm history without stopping the power supply.
