High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• Set the multi-function output P1 to P5 terminals and the multi-function relay output (MA, MB) terminal
to output specifications either of NO (Normally open contact) or NC (Normally closed contact)
individually.
• The multi-function output P1 to P5 terminals are for open collector output.
• The RUN signal is output from the multi-function output P1 to P5 terminals and the multi-function
relay output (MA, MB) terminal during operation.
• Allocate one of the Multi-function Output P1 to P5 Selection (C021 to C025) or the Multi-function
Relay Output (MA, MB) Function Selection (C026) to 00 (RUN).
• This signal is also output when DC injection braking is active.
• The RUN signal is output even when the inverter does not output because the frequency reference is
0 Hz, as long as the RUN command is ON.
The timing diagram is as follows.
The inverter outputs the RUN signal until the motor is stopped even if the RUN command (FW) turns
OFF.
