Terminals [Y1] function to [Y2] function
Terminal [30A/B/C] function (Relay output)
E20 through E21 and E27 assign output signals to general-purpose, programmable output terminals, [Y1], [Y2]
and [30A/B/C]. These function codes can also switch the logic system between normal and negative to define how
the inverter interprets the ON or OFF state of each terminal. The factory default setting is normal logic system
“Active ON.”
Terminals [Y1] and [Y2] are transistor outputs and terminals [30A/B/C] are contact outputs. In normal logic, if an
alarm occurs, the relay will be energized so that [30A] and [30C] will be closed, and [30B] and [30C] opened. In
negative logic, the relay will be de-energized so that [30A] and [30C] will be opened, and [30B] and [30C] closed.
This may be useful for the implementation of failsafe power systems.
• When negative logic is employed, output signal is OFF(active) while the inverter is powered OFF. To
avoid causing system malfunctions by this, interlock these signals to keep them ON using an external
power supply. Furthermore, the validity of these output signals is not guaranteed for approximately 1.5
seconds (for 22 kW or below) or 3 seconds (for 30 kW or above) after power-ON, so introduce such a
mechanism that masks them during the transient period.
• Terminals [30A/B/C] use mechanical contacts. They cannot stand frequent ON/OFF switching. Where
frequent ON/OFF switching is anticipated (for example, by using frequency
arrival
signal), use
transistor outputs [Y1] and [Y2] instead.
The service life of a relay is approximately 200,000 times if it is switched ON and OFF at one-second
intervals. For signals expected to be turned ON/OFF frequently, use terminals [Y1] and [Y2] for output.
The tables given on the following pages list functions that can be assigned to terminals [Y1], [Y2], and [30A/B/C].
The descriptions are, in principle, arranged in the numerical order of assigned data. However, the signal is related
has been described together. Refer to the function codes or signals in the “Related function codes/signals (data)”
column, if any.
Explanations of each function are given in normal logic system “Active ON.”
