Typical Multiple Drive Connection Examples
Input Connection Example
Multiple Digital
Input Connections
Customer Inputs can
be wired per
External Supply
(SRC) or Internal
Supply (SNK)
examples on
page 1-15 .
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.
