Notes/comments:If the limit in the feedback monitor is exceeded, warning 90 feedback
monitor is issued. The SLC monitors warning 90 feedback monitor. If warning 90 feed-
back monitor becomes true, relay 1 is triggered. External equipment could indicate that
service is required. If the feedback error goes below the limit again within 5 s, the drive
continues and the warning disappears. But relay 1 persists until [Off/Reset] is pressed.
10.7 Encoder Connection
The purpose of this guideline is to ease the setup of encoder connection to the drive. Before setting up the encoder, the basic settings for
a closed loop speed control system are shown.
