Rating, etc. Application Explanation
1 changeover contact output
indicates that the inverter fault
occurs.
When a fault occurs, terminals B-C
are open (A-C are closed). In the
normal state, terminals B-C are
closed (A-C are open).
When this signal is output, the motor
coasts.
1 changeover contact output
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.*5
Switched low when the output
frequency reaches within the range of
10% (initial value) of the set
frequency. Switched high during
acceleration/deceleration and at a
F700
stop.*5
Switched low when stall prevention is
activated by the stall prevention
function. Switched high when stall
prevention is cancelled. *5
D700
Switched low when the protective
circuit is activated due to an
instantaneous power failure and
under voltage. *5
This open collector output is switched
low when the output frequency
reaches or exceeds the detection
frequency set in [Pr. 42] (initial value
is 6Hz) and [Pr. 43] (initial value is
9999 (same as the [Pr. 42] setting))
and is high when it is less than the
detection frequency.
Common terminal for terminals RUN,
SU, OL, IPF, and FU.

Isolated from terminals SD and 5.
Do not earth (ground).
The output voltage is a 8VDC pulse-
shaped waveform.
Connect a 1mA moving-coil type DC
: 2mA
ammeter.
F700
When the frequency is as set in [Pr.
: 1mA
D700
55] (initial value is 60Hz), the output
pulse frequency is 1440pulse/s.
Terminal FM is used as high speed
pulse train output terminal of open
collector output.
To use as pulse train output terminal,
the [Pr. 291] setting needs to be
changed.
Factory-set to provide 10VDC at full-
scale value, which is proportional to
the monitor value.
When the frequency is as set in [Pr.
or
55] (initial value is 60Hz), the output
voltage is 10VDC.
With the PU connector,
communication can be made through
RS-485. (1:1 connection only)
With the RS-485 terminals,
communication can be made through
RS-485.
