Output of the OL signal
I002515E
NOTES OL signal is assigned to the terminal OL in the initial setting. The OL signal can also be assigned to
other terminals by setting "3 (positive logic) or 103 (negative logic)" in any of Pr. 190 to Pr. 196
(output terminal function selection).
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.
