Ex.
The following shows an example of when the 17th error occurs. The 17th error is stored in Error history No.1, and 'Latest
address of error history' (Un\G1) is overwritten with the value 3600 (start address of Error history No.1).
'Latest address of error history'
(Un\G1): 3600
Un\G3600
Un\G3610
Un\G3620
Un\G3750
• Once the error history storage area becomes full, subsequent error information will overwrite the existing
data, starting from Error history No.1 (Un\G3600 to Un\G3609), and the overwriting continues sequentially
thereafter. The overwritten history is deleted.
• The same processing is performed for Alarm history when an alarm occurs.
