Operation selection at power failure and
instantaneous power failure
4.13.3 Power failure signal (Y67 signal)
When output is shutoff due to a power failure or undervoltage, the Y67 signal turns ON regardless of the automatic
restart after instantaneous power failure function setting.
Y67 signal turns OFF at power failure recovery or undervoltage recovery.
To use Y67 signal, set "67 (positive logic) or 167 (negative logic)" in any of Pr. 190 to Pr. 192 (Output terminal function
selection) to assign the function.
CAUTION
⋅ Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.
