6.8. Program example for trip information reading
Example 8 shows a ladder logic to read the trip information of station 1 inverter to D1.
Trip history No. 1, No. 2 reading code number: 74H (hexadecimal)
The reply code at the time of instruction code execution is set to D2.
For example of trip information
Read dara: 2D0EH
b15 b8 b7 b0
0 01 0 1 10100001110
(2DH) (0EH)
Past trip code Current trip code
e-13(Error code: 2DH) ol2(Error code: 0EH)
" Over speed fault " " Motor overload "
Refer to 5.5.9 for detail. }

Write trip history No.1, No.2 read
code (H74) to RWw2.
Turn on the instruction code execution

Read alarm data (RWr3) and reply code
(RWr2) to D1 and D2 when the
instruction code execution completion
flag (RX0F) turns on.

Turn off the instruction code execution
