• The Inverter running and start command ON (RUN3) signal is ON while the inverter is running or while the start command
signal is ON.
• The RUN2 and RUN3 signals are also ON when the start command signal is ON or during zero speed control with the
speed command value 0.

*1 When the start signal is ON and the frequency command is 0 Hz, such state is designated as "during zero speed control".
*2 The signal is OFF during power failure or undervoltage.
*3 This means the state during a fault occurrence or while the MRS signal is ON, etc.
*4 The signal is OFF while power is not supplied to the main circuit.
• To use the RY, RUN, RUN2, or RUN3 signal, set the corresponding number selected from the following table in any
parameter from Pr.190 to Pr.196 (Output terminal function selection) to assign the function to an output terminal.

NOTE
• The RUN signal (positive logic) is initially assigned to the terminal RUN (standard models only).
 Fault output (ALM) signal
• The fault signal (ALM signal) is output when an inverter protective function is activated.
