Function assignment of external terminals
Alarm output signal (ALM)
If the inverter comes to trip, the ALM signal is output. (Refer to section 7.1.)
Fig. 6-60: Alarm signals
NOTE
The ALM signal is assigned to the ABC contact in the default setting. By setting "99" (positive logic)
or "199" (negative logic) in Pr. 190 to Pr. 192 "Output terminal function selection", the ALM signal
can be assigned to the other signal.
Fault output 3 (power-off signal) (Y91)
The Y91 signal is output at occurrence of a fault attributable to the failure of the inverter circuit or a
fault caused by a wiring mistake. When using the Y91 signal, set "91" (positive logic) or "191" (negative
logic) to any of Pr. 190 to Pr. 192 "Output terminal function selection" to assign the function to the out-
put terminal.
Operation Panel Indication
Tab. 6-33: Faults that lead to Y91 signal output
NOTE
At occurrence of output side earth (ground) fault overcurrent (E.GF), overcurrent trip during accel-
eration (E.OC1) may be displayed. At this time, the Y91 signal is output.
