and a voltage/current input switch correctly, then input analog signals in accordance with the settings.
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.

Relay output (fault
output)
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

Open collector
RUN
Inverter running
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 indicates that the open collector output transistor is on
(conducts).
High indicates that the transistor is off (does not conduct).)

Keep these open. Otherwise, the inverter may be damaged.
Do not remove wires for shorting across terminal S1 and SC, across terminal S2 and SC. If one of these wires
is removed, the inverter cannot be operated.
