Transistor outputs
[Y1] Transistor
output 1
(1) Various signals (running signal, frequency reached signal, overload forecast signal, etc)
set up by function code E20, E21 can be output. For details, refer to Chapter 5
“FUNCTION CODE”.
(2) The operating mode of the transistor output terminals [Y1], [Y2] can be switched to “ON
(active ON) at signal output” or “OFF (active OFF) at signal output”.

Figure 2.2-18 Transistor Output Circuit
• Connect a surge absorbing diode between the terminals the excitation coil
when connecting control relays.
• When a power source is needed for the circuit to be connected, terminal PLC
can be used as a power source terminal. Rated voltage: DC+24 V (power
supply voltage fluctuation range: DC+22 to +27 V), maximum 50 mA). In this
case, terminal [CMY] must be shorted to terminal [CM].
[Y2] Transistor
output 2
[CMY] Transistor
output common
This terminal is the common terminal for transistor output signals.
This terminal is insulated from terminals [CM] and [11].

When connecting the programmable controller to terminals [Y1], [Y2].
The circuit configuration example for connecting the inverter transistor output to the programmable controller is
shown in Figure 2.2-19. Circuit (a) in Figure 2.2-19 shows the programmable controller input circuit as sink
input and circuit (b) shows as the source input case.

Contact output
[30A/B/C] Integrated
alarm output
(1) When the inverter stops with an alarm, output is generated on the relay contact (1C).
Contact rating: AC250 V 0.3 A cos
φ = 0.3, DC48 V 0.5 A
(2) Terminals can be switched to “Terminals [30A to 30C] shorted (excitation: active ON) at
ON signal output” or “Terminals [30A to 30C] open (non-excitation: active OFF) at ON
signal output”
