Function assignment of external terminal and control
(3) Fault output (ALM) signal
(4) Fault output 3 (power-off signal) (Y91) signal
The Y91 signal is output at occurrence of a fault attributable to the failure of the drive unit 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, 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
for the fault description.)
If the drive unit comes to trip, the ALM signal is output.
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
for the drive unit fault description.

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.
