Input signals
Use a wire end ferrule and a cable for the connection to the terminals where the end is striped appropriately.
Single-core cables can be connected directly to the terminals after removing the insulation.

Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may
occur with neighboring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it
b
Crimp the blade terminal.
Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimp
-
ing is inappropriate, or the face is damaged.

Description
10
Frequency setting
power supply
Used as the power supply for an external device such as a fre
-
quency setting potentiometer or digital panel meter.
2
Frequency setting
(voltage)
Inputting 0 to 5 V DC (or 0 to 10 V DC) provides the maximum
output frequency at 5 V (or 10 V) and makes input and output
proportional.
4
Frequency set
-
ting (current)
Inputting 4 to 20 mA DC
(or 0 to 5 V, 0 to 10 V)
provides the maximum
output frequency at
20 mA and makes input
and output proportional.
This input signal is valid
only when the AU signal
is ON (terminal 2 input is
invalid).
5
Frequency
setting and
analog outputs
common
Terminal 5 represents the reference point (0 V) for all analog set
-
point values and for the analog output signal AM (voltage). The
terminal is isolated from the reference potential of the digital cir
-
cuit (SD).
10
PTC input
(PTC sensor)
Terminals 10 and 2 serve as an input for a PTC sensor (thermal
motor protection).

A, B, C
Relay output
A changeover contact output that indicates that an inverter's
protective function has been activated and the outputs are
stopped.
