Design
D 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.
D Selecting Frequency Reference Input Method

Current input
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.
