If connecting a programmable controller to terminals [Y1] to [Y4]
An example of a circuit configuration in which inverter transistor output is connected to a
programmable controller is shown in Fig. 2.2-23 below. Circuit (a) in shows the programmable controller
input circuit as the sink input, and circuit (b) shows it as the source input.
(a) Connection drawing of connection with sink
input type programmable controller
(b) Connection drawing of connection with
source input type programmable controller

Contact output
[Y5A]
[Y5C]
General-
purpose relay
output
(1) The same signals as those of terminals [Y1] to [Y4] can be selected and output as multi-
purpose relay outputs.
Contact capacity: 250 VAC 0.3 A cosφ = 0.3,
48 VDC 0.5 A
(2) It is possible to switch between a "short circuit between terminals [Y5A] to [Y5C] when an
ON signal is output (excitation: active ON)" or an "open circuit between terminals [Y5A] and
[Y5C] when an ON signal is output (non-excitation: active OFF)".
[30A]
[30B]
[30C]
Integrated
alarm output
(1) When the inverter stops with an alarm, an integrated alarm is output at the relay contact
(1C).
Contact capacity: 250 VAC 0.3 A cosφ = 0.3,
48 VDC 0.5 A
(2) The same signals as those of terminals [Y1] to [Y4] can be selected and output.
(3) It is possible to switch between a "short circuit between terminals [30A] and [30C] when an
ON signal is output (excitation: active ON)" or an "open circuit between terminals [30A] and
[30C] when an ON signal is output (non-excitation: active OFF)".

ns link port 2
This is an input/output terminal used to connect a computer or programmable controller, etc.
by RS-485 communication. (Refer to "2.2.7 Switching switches" for details on terminating
resistance).
With a multi-drop (cross-wire) connection, use the recommended rod terminal.
(Refer to "2.2.6 [ 1 ] Screw specifications and recommended wire size (control circuit
terminals)" for details on recommended rod terminals).
