Function codes d51, d55, d69, d98 and d99 appear on the monitor, but they are reserved for
particular manufacturers. Unless otherwise specified, do not access these function codes.

6.3.13 U codes (Customizable logic functions)

U00 Customizable Logic (Mode selection)
U01 to U70 Customizable Logic: Step 1 to 14 (Setting)
U71 to U77 Customizable Logic Output Signal 1 to 7 (Output selection)
U81 to U87 Customizable Logic Output Signal 1 to 7 (Function selection)
U92 to U97 Customizable Logic Conversion Coefficients
The customizable logic function allows the user to form logic circuits and calculation circuits
with respect to digital and analog I/O signals, process signals arbitrarily, and establish
simplified relay sequences in the inverter.
In the customizable logic, the following can be specified as one step (component) to establish
sequences using 14 steps in total:
(1) Digital 2 inputs/digital 1 output + logic calculation (including timer)
(2) Analog 2 inputs/analog 1 output/digital 1 output + value calculation
(3) Analog 1 input/1 digital input/analog 1 output + value calculation/logic calculation
