REMARKS
 The ALM signal is assigned to the ABC contact in the initial setting. By setting "99 (positive logic) or 199 (negative logic) in
Pr.190 or Pr.192 (output terminal function selection), the ALM signal can be assigned to the other signal.
 Refer to page 298 for the inverter fault description.

Fault output 3 (power-off signal) (Y91 signal)
 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 Pr.190 or Pr.192 (output terminal function
selection) to assign the function to the output terminal.
 The following table indicates the faults that will output the Y91 signal. (Refer to page 297 for the fault description.)

Indication
E. BE
Brake transistor alarm detection
Output side earth (ground) fault overcurrent at
E.GF
start
E.LF
Output phase loss
E.PE
Parameter storage device fault
E.CPU
CPU fault
E.IOH
Inrush current limit circuit fault
REMARKS
 At occurrence of output side earth (ground) fault overcurrent (E.GF), overcurrent trip during acceleration(E.OC1) may be
displayed. At this time, the Y91 signal is output.
