Connection Example
Multiple Digital
Input Connections
Customer Inputs can
be wired per the
External Supply (SRC)
example on
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:
Digital inputs on multiple drives 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.
