Output signal circuit
The output signals of this inverter are open-collector outputs. Therefore, an external
power supply is needed to operate the output signals. Use an external power supply
with a voltage range not exceeding 26.4 V, and connect a limiting resistor
appropriate for the power supply voltage so as not to cause the current to exceed
10 mA. No external power supply is required if the output signals are not used.
The output circuit terminals are insulated to the reinforced insulation standard for
protection against dangerous voltages.
The output signals of this inverter are transistor open-collector outputs. In other
words, the status of each output signal does not indicate the signal voltage level, but
it represents the ON (energized) or OFF (not energized) status of the internal
photocoupler.
RUNNING
ALARM
COM
The RUNNING output remains ON when the inverter is running, and turns OFF
when it is stopped (normally closed).
The ALARM output remains ON when the inverter is normal, and turns OFF when
an alarm generates (normally closed).

The ALARM output produces a pulsed output waveform while a blinking alarm
code is displayed.
