■ Wiring for Analog Signal Terminals (Terminal No.13 to 16, 24)

·When parameter P004 is set to "2", frequency setting will be made through
external potentiometer.
·When using external potentiometer for frequency setting, select a
potentiometer of "10 kΩ, 1/4 W or higher" rating.
·When parameter P004 is set to "5" (4 to 20 mA) or "6" (0 to 20 mA), frequency
setting will be made through analog current signal.
·When using analog current signal (4 to 20 mA, 0 to 20 mA) for frequency
setting, connect a resistor of "200 Ω, 1/4 W" rating. (Failure to do so may
damage the inverter.)
·If the unit version is Ver3.0 or later, a built-in 200 Ω resistor should be set
between terminal No.24 and COM. If analog input signal of 4 to 20 mA / 0 to 20
mA is used, external resistor connection can be eliminated by connecting
terminal No.24 to No.14 or No.16.

■ Wiring for RS485 Communication Terminals (Terminal No.19 to 23)

The following figure shows the terminals used when connection is made
between PC and PLC via RS485 communication lines.
