NOTE
To change the input specification for terminal 4, set Pr. 267 and the voltage/current input switch correctly, then input
the analog signal relevant to the setting. Applying a voltage with voltage/current input switch in "I" position (current
input is selected) or a current with switch in "V" position (voltage input is selected) could cause component damage
of the inverter or analog circuit of output devices.
Connecting the power supply to the inverter output terminals (U, V, W) will damage the inverter. Do not perform such
wiring.
indicates that terminal functions can be selected using Pr. 178 to Pr. 182, Pr. 190 and Pr. 192 (I/O terminal function
selection).
The terminal names and functions shown here are the initial settings.
The terminals S1, S2, SC, and SO are for manufacturer setting. Do not connect anything to these.
Doing so may cause an inverter failure. Do not remove the shortening wires across the terminals S1 and SC and the
terminals S2 and SC. Removing either shortening wire disables the inverter operation.
1 changeover contact output indicates that the inverter protective function has activated and
the output stopped.
Fault: discontinuity across B-C (continuity across A-C),
Normal: continuity across B-C (discontinuity across A-C)
Contact capacity:230VAC 0.3A (power factor =0.4) 30VDC 0.3A
Switched Low when the inverter output frequency is equal to
or higher than the starting frequency (initial value 0.5Hz).
Switched High during stop or DC injection brake operation.
(Low is when the open collector output transistor is ON
(conducts). High is when the transistor is OFF (does not
conduct).)
Common terminal of terminal RUN.

Selected one e.g. output frequency from monitored items.
(Not output during inverter reset.)
The output signal is proportional to the magnitude of the
corresponding monitored item.
