High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• The set frequency value after UP/DWN adjustment can be stored. Select whether to store the setting
in the UP/DWN Storage Selection (C101).
The set frequency value after adjustment will be stored when the power supply is turned off.
Until stored, you can clear the set frequency value after adjustment and restore the value before
adjustment.
To clear the frequency reference value adjusted via UP/DWN, set the Multi-function Input S1 to S8
Selection (C001 to C008) to 29 (UDC) and turn ON/OFF the terminal UDC.
• Use this function when the Digital Operator is not selected as the frequency reference/RUN
command source to force enable operation via the Digital Operator by turning ON/OFF the
multi-function input terminal to which the function is allocated.
• To allocate this function, set the Multi-function Input S1 to S8 Selection (C001 to C008) to 31 (OPE).
• When the forced operator function is allocated to a multi-function input terminal, the inverter accepts
the frequency reference source and RUN command via the sources selected in A001 and A002 if the
signal is OFF and via the Digital Operator if the signal is ON.
• If you switch on/off this function during operation, the RUN command will be reset to stop the inverter
output. In this case, to ensure safety, once turn OFF the RUN command from the selected command
source and input it again before resuming operation.
