Offset/Gain Initialization Function - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Ex.
When the 17th error occurs:
The 17th error is stored in Error history No. 1, and the value 3600 (start address of Error history No. 1) is stored to Latest
address of error history.
'Latest address of error history'
(Un\G1): 3600
• Once the error history storage area becomes full, the existing data is overwritten in order, starting with 'Error
history No. 1' (Un\G3600 to Un\G3609), and error history logging continues. The overwritten history is
deleted.
• The same processing is performed for Alarm history when an alarm occurs.
• The stored error history is cleared when an analog output module is powered off or the CPU module is
reset.

1.
Set the mode to normal output.
2.
Set "D/A conversion not allowed (1)" in 'CH1 D/A conversion enable/disable setting' (Un\G500) to 'CH4 D/A conversion
enable/disable setting' (Un\G1100). Then, turn offonoff 'Operating condition setting request' (Un\G70, b9).
3.
Set "E20FH" to 'Offset/gain initialization enabled code' (Un\G305).
4.
Turn ON (1) 'Offset/gain initialization request' (Un\G70, b5).
After completion of the offset/gain initialization function, 'Offset/gain initialization enable code' (Un\G305) is initialized to
'0000H' and 'Offset/gain initialization completed flag' (Un\G69, b5) turns on (1).
