Selecting RS-422/485 Termination Resistance
•
Termination resistance can be selected by setting pin 1 of the SW2 to ON. The default setting for the
pin is OFF.

Selecting Frequency Reference Input Method
•
By using pin 2 of SW2, voltage input or current input can be selected as the input method for frequency
reference. The default setting is for voltage input.
Parameter settings are required together with the selection of the frequency reference input method.

Pin 2 setting
Frequency reference selection
(parameter n004)
Voltage input (default setting)
V (OFF)
Set value 2
Current input
I (ON)
Set value 3 or 4
Note
Do not set pin 2 to ON for current input while voltage is being input, otherwise the resistor in the
input circuit may burn out.
D
Frequency Reference Input by Pulse Train Input
•
The RP terminal can input or output a PLC or external pulse generator signal directly to the Inverter if
an analog signal is unable to provide an accurate reference.
•
This allows speed ratio and tracking operation between inverters.
