Alarm code
• Upon alarm generation, the ALM output (pin.34) is turned OFF. (ON is the normal status)
• In the event of any alarm, the binary alarm code is output to (AC 0 to 5) as the STEP No. is output
in binary to PO 0-8, whose operation has been completed in Function modes 0 through 3. (See
"2-3 How to obtain STEP No. whose operation has been completed (
→
P.4-5)
".)
• Assuming the (AC) is equivalent to each binary number digit, convert them into decimal numbers
to obtain an alarm code.
• Obtain the decimal numbers of the (AC) being ON from the table above, and add all the numbers
up to determine the current alarm code.
• Example) When (AO 5) (=32), (AO 4) (=16), (AO 1) (=2), and (AO 0) (=1) are ON
32 + 16 + 2 + 1 = 51, so alarm code = 51.
