5-9-2 Multi-function Input Operation Selection
The multi-function input terminals can be set to either NO (NO contact) or NC (NC contact) individually.
This manual describes each function with the Multi-function Input 1 to 7 Operation Selection (C011 to
C017) set to 00 (NO: NO contact). Note that the operations of set signals are reversed when you set
them to 01 (NC: NC contact).

5-9-3 Input Terminal Response Time
• Set the response time for each multi-function input 1 to 7 terminal independently.
This function is effective for removing noise caused by chattering etc.
• If the terminal input becomes unstable because of chattering, increase the set value.
However, increasing the set value results in a slow response.
The setting range is 0 to 200, which provides a response time of approximately 2 to 400 ms.

5-9-4 Forward RUN Command (FW) and Reverse RUN Command (RV)
• To input the forward and reverse RUN commands via the control circuit terminals, set the Multi-func-
tion Input 1 to 7 Selection (C001 to C007) to 00 (FW) and 01 (RV).
• By default, the Multi-function Input 1 Selection (C001) is set to 00 (FW) and the Multi-function Input 2
Selection (C002) is set to 01 (RV), respectively.
• To input the RUN command via these control circuit terminals, set the 1st/2nd RUN Command Selec-
tion (A002/A202) to 01 (Control circuit terminal block).
• If the terminals FW and RV turn ON simultaneously, the inverter will stop without displaying any
alarm. It will start operating again when either of these terminals turns OFF.
