can be wired per
External Supply
(SRC) or
Internal Supply
(SNK).
When connecting a single input such as Run, Stop, Reverse or Preset
Speeds to multiple drives, it is important to connect I/O Terminal 04
common together for all drives. If they are to be tied into another common
(such as earth ground or separate apparatus ground) only one point of
the daisy chain of I/O Terminal 04 should be connected.
Multiple Analog
Connections
When connecting a single potentiometer to multiple drives it is important
to connect I/O Terminal 14 common together for all drives. I/O Terminal
14 common and I/O Terminal 13 (potentiometer wiper) should be daisy-
chained to each drive. All drives must be powered up for the analog signal
to be read correctly.
