▶ Special D register of PLC for monitoring inverter trip information
Special Register Description
D4490 Inverter Trip Save Area 1
D4491 Inverter Trip Save Area 2
D4492
Inverter Trip Save Area 3
D4493
Inverter Trip Save Area 4
When the iS7 inverter is powered on, the special D register (D4490~D4493) for inverter trip monitoring is
initialized to 0x00FF. The order of storing inverter trip information is D4490 Î D4491 Î D4492 Î
D4493. Up to 4 inverter trips can be stored, and the 5
th
will overwrite D4490, and the 6
th
will overwrite
D4491. In this manner, new inverter trip data are stored in the special D register.
