The relationship between function codes and relay output functions is as follows.
Function code Functions Setting range
o01 Relay contact output 6 (Function selection)
o02 Relay contact output 7 (Function selection)
o03 Relay contact output 8 (Function selection)
o04 Relay contact output 9 (Function selection)
o05 Relay contact output 10 (Function selection)
o06 Relay contact output 11 (Function selection)
o07 Relay contact output 12 (Function selection)
0 to 235,
1000 to 1235 (For negative logic)
o01 through o07 assign output signals to general-purpose, programmable relay outputs 6 through 12.
These function codes can also switch the logic system between normal and negative to define the
property of those relay outputs so that the inverter logic can interpret either the ON or OFF status of
each relay output as active.
When a negative logic is employed, all output signals are active (e.g., an alarm would be recognized)
while the inverter is powered OFF. To avoid causing system malfunctions by this, interlock these
signals to keep them ON using an external power ON signal. Furthermore, the validity of these output
signals is not guaranteed for approximately 2 seconds after power ON, so introduce such a mechanism
that masks them during the transient period.
