*1 The signal is OFF during power failure or undervoltage.
*2 This means the state during a fault occurrence or while the MRS signal is ON, etc.
*3 The signal is OFF while power is not supplied to the main circuit.
• To use the RY, RUN, 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.
Output signal
RY
RUN
RUN3
NOTE
• The RUN signal (positive logic) is initially assigned to the terminal RUN.
 Fault (ALM) signal and Fault output 2 (ALM2) signal
• The fault signal (ALM or ALM2 signal) is output when an inverter protective function is activated.
• The ALM2 signal stays ON during the resetting the inverter after the Fault occurs.
• To use the ALM2 signal, set "94 (positive logic) or 194 (negative logic)" in any parameter from Pr.190 to Pr.196 (Output
terminal function selection) to assign the function to an output terminal.
• The ALM signal is initially assigned to the relay terminals A1, B1, and C1.

 Input power shutoff like magnetic contactor (Y91 signal)
• The Fault output 3 (Y91) signal is output when a fault originating in the inverter circuit or a connection fault occurs.
• To use the Y91 signal, set "91 (positive logic) or 191 (negative logic)" in any parameter from Pr.190 to Pr.196 (Output
terminal function selection) to assign the function to an output terminal.
• The following is the list of faults that output the Y91 signal. (For details on faults, refer to
Inrush current limit circuit fault (E.IOH)
CPU fault (E.CPU)
CPU fault (E.6)
CPU fault (E.7)
Parameter storage device fault (control circuit board) (E.PE)
