(SRC) examples 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.
