(1) Any one of output signals that can be assigned to terminals [Y1]
and [Y2] can also be assigned to this relay contacts, as a
general-purpose relay output, in order to use it for outputting a
signal.
(2) Whether excitation or non-excitation causes this terminal to
output a signal can be switched.
(3) Contact capacity and the life are shown by table below.

[30A/B/C]
(1) When the protective function is activated, this terminal outputs
a contact signal (1C) to stop the motor.
(2) Any one of output signals that can be assigned to terminals [Y1]
and [Y2] can also be assigned to this relay contact as a
general-purpose relay output, in order to use it for outputting a
signal.
(3) Whether excitation or non-excitation causes this terminal to

These I/O terminals are used as a communications port that
transmits data through the RS-485 multipoint protocol between the
inverter and a computer or other equipment such as a PLC or
elevator controller.
