The analog voltage/current or
variable resistor input wiring for
the frequency reference is
incorrect.
Wire correctly.
• For the analog voltage or variable resistor
input wiring, measure the voltage between
the terminals FC and SC with a tester etc.
to check that the voltage is correct.
• For the analog current input wiring, with the
wires disconnected, measure the current
flowing between the power supply and FI
terminals with a tester etc. to check that the
current is correct.

To use the safety function, turn ON both of the
safety input terminals GS1 and GS2. To dis-
able this function, set the safety function
selector switch to OFF.
P. 7-97
The Multi-function Input S1 to
S7 Selection (C001 to C007) is
set to 18 (RS: Reset), 14 (CS:
Commercial switching), or 11
(FRS: Free-run stop) and that
terminal is ON.
Turn OFF the terminal to which the function is
allocated.

RUN command) and that termi-
nal is ON.
Turn ON the terminal to which the function is
allocated.
P. 7-38
The wiring from the inverter to
the motor, or the internal wiring
