Notes/comments:
If the limit in the feedback monitor is exceeded, warning 61, feedback monitor is issued.
The SLC monitors warning 61, feedback monitor. If warning 61, feedback monitor be-
comes true, relay 1 is triggered.
External equipment could indicate that service is required. If the feedback error goes be-
low the limit again within 5 s, the drive continues, and the warning disappears. Relay 1
persists until [Off/Reset] is pressed.
