6.11.5 Function codes
• Incorrect use of function code data may result in a hazardous state. Consequently, re-check data after finishing
setting and writing data.
Risk of accident
Installation of the DI interface card allows use of function codes o01 to o04. These function codes are not
normally (when the option had not been installed) displayed on the keypad.

6.11.5.1 Data latch function
DI input data is normally captured internally and applied inside the inverter every 1 ms. A data latch
function can be used when you wish to hold DI input data or reduce variation in lower bits when
capturing input from an external A/D converter.
[Setting method]
Set function codes X1 to X14 corresponding to the desired contact to 55 (DIA) or 56 (DIB) to assign data
latch operation. Then set the contact in question as follows:
On: Normal capture
Off: DI input hold (data is not captured, and the last data value before the contact was turned off)
