NOTE
• The Y32 signal is always OFF under V/F control, Advanced magnetic flux vector control, Real sensorless vector control, and
PM sensorless vector control.
 Fault output (ALM) signal
• The fault signal (ALM signal) is output when an inverter protective function is activated.
• The ALM signal is assigned to the terminals A, B, and C in the initial status.

NOTE
• For details of the inverter faults, refer to the Instruction Manual (Maintenance).
 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 the details of faults, refer to the Instruction Manual
(Maintenance).)
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)
Parameter storage device fault (main circuit board) (E.PE2)
Output side earth (ground) fault overcurrent (E.GF)
Output phase loss (E.LF)
Brake transistor alarm detection (E.BE)
Internal circuit fault (E.13)
 Changing the special relay function for the PLC function
• For the PLC function, the function of special relays (SM1225 to SM1234) can be changed by setting Pr.313 to Pr.322. (For
the details of the PLC function, refer to the PLC Function Programming Manual.)
