Operation selection at power failure Parameter
6 - 168
Power failure deceleration signal (Y46 signal)
The Y46 signal is on during deceleration at an instantaneous power failure or during a stop after de-
celeration at an instantaneous power failure.
After a power failure stop, the inverter can not start even if power is restored the start command is giv-
en. In this case, check the power failure deceleration signal (Y46 signal) (at occurrence of input phase
loss (E.ILF), etc.).
For the Y46 signal, set "46" (forward operation) or "146" (reverse operation) to any of Pr. 190 to Pr. 192
"Output terminal function selection" to assign the function.
NOTES During a stop or trip, the power failure stop selection is not performed.
Changing the terminal assignment using Pr. 190 to Pr. 192 "Output terminal function selection"
may affect the other functions. Please make setting after confirming the function of each terminal.

CAUTION:
If power-failure deceleration operation is set, some loads may cause the inverter to trip and the
motor to coast. The motor will coast if enough regenerative energy is given from the motor.
