Fault output signals (ALM, ALM2)
NOTE
• For the inverter fault details, refer to
.
Input MC shutoff signal (Y91)
• 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 of
Pr.190 to Pr.196 (Output terminal
function selection)
to assign the function to the output terminal.
• The following table shows the faults that output the Y91 signal. (For the fault details, refer to
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.)

Parameters referred to
Pr.13 Starting frequency
,
Pr.76 Fault code output selection
• The Fault (ALM, ALM2) signals are output when the inverter
protective function is activated.
• The ALM2 signal stays ON during the reset period after the fault
occurs.
• To use the ALM2 signal, set "94 (positive logic) or 194 (negative
logic)" in any of
Pr.190 to Pr.196 (Output terminal function
selection)
to assign the function to the output terminal.
• The ALM signal is assigned to the A1B1C1 contacts in the initial
status.
