FDBK behavior (Latch /No Latch):
If FDBK is latched when the STO alarm occurs, the status of FDBK does not change even when
the alarm is cleared. Please note that when more than one alarm occurs, the drive panel only
shows AL500.

Example of Latching:
If Logic C P2.093 = XX22 is set, the FDBK status is closed when safety signal is lost and AL005
occurs.
1.
Since FDBK is selected as Latch, even when the safety signal is back to normal, the FDBK
status remains closed. To reset FDBK:
(1) Reconnect the power supply: FDBK status returns to “open”.
(2) Do not reconnect the power supply. Instead, set P2.093 to XX12 to make the FDBK
status return to “open”. Then set P2.093 to XX22 again. This step sets the FDBK
behavior to Latch.
2. After the FDBK status is restored, you can clear the alarms by the normal corrective
actions. In this case, you can clear AL500 by DI.Alm Reset.

Example of Not Latching:
If Logic C P2.093 is set to XX12, the FDBK status is closed when the safety signal is lost and
AL500 occurs.
1.
Since FDBK is selected as No Latch, when the safety signals return to normal, the FDBK
status automatically changes from short-circuited to normal when AL500 occurs. Setting
P2.093 to XX12 again is not required.
2. After the FDBK status is restored, you can clear the alarms by the normal corrective
actions. In this case, you can clear AL500 that by DI.Alm Reset.
