5-10-4 Signal during RUN (RUN)
• The RUN signal is output during inverter operation.
• Allocate one of the Multi-function Output P1 to P5 Selection (C021 to C025) or Multi-function Relay
Output (MA, MB) Function Selection (C026) to 00 (RUN).
• The RUN 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.
• This signal will be output when the output frequency reaches the set frequency reference.
• 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 01 (FA1).
• The hysteresis of this frequency arrival signal is calculated as follows.
