Typical Multiple Drive Connection Examples
Input/Output Connection Example
Multiple Digital Input
Connections
Customer Inputs can be
wired per External Supply
(SRC).
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.

ATTENTION: I/O Common terminals should not be tied
together when using SNK (Internal Supply) mode. In
SNK mode, if power is removed from one drive,
inadvertent operation of other drives that share the
same I/O Common connection may occur.
