Detailed Wiring Information
9.0 DETAILED WIRING INFORMATION
Connector pin-out detail is provided in the prior section of this manual. This section deals with the details of the
internal operation of the drive connections. This information is provided to allow the system designer insight
sufficient to create a robust system wiring plan.

ISCUSSION
Bred from the older days of PLCs and the newer days of digital logic some words have become standard in some
industries. Some terms are described here to make this document easier to understand:
Common Rail: Common rail is simply a term meaning that more than one input (or output) has one terminal of its
:
device tied to the other inputs (or outputs). An example of a common rail is shown below
Figure 8.1 Common Rail Illustration
In Figure 8.1 each input is represented by the LED. Each input has a common connection (Anode) to the positive
side of the I/O power source. This is what is referred to as a common rail. It is also allowable to modify this circuit
where each anode goes to the switch and each resistor is tied to the negative side of the I/O supply.
Sourcing Input: A sourcing input is an input that must be taken to ground to operate. (It SOURCES current). The
above figure shows discrete inputs arranged for sourcing. These are used with sinking output device such as
Open Collector drivers. Some manufacturers of driving devices refer to sinking outputs as 'NPN' devices after
then name of the driving device transistor type.
Sinking Input: A sinking input has the opposite arrangement of souring inputs where a current-to-ground must be
supplied to the input. (Sinking current to ground). These are used with sourcing output devices. Some
manufacturers of driving devices refer to sinking outputs as 'PNP' devices after then name of the driving device
transistor type.

ONNECTIONS
It has been noted throughout this manual that a connection to earth ground is required. Multiple connections may
be required. The connection to earth ground can affect safety and electrical noise immunity and emissions. The
purpose of this text is to alert the user to the requirement of the earth ground connection. When connecting earth
grounds it is often required to have a connection that cannot come undone so ring lugs to the frame is highly
recommended. Each earth ground wire should go directly back to the central earth ground block in the cabinet; do
not daisy-chain the connections. Large gage wires consisting of many fine strands of wire are superior to other
types for conducting high frequency noise and the use of high strand count wire is recommended.

ERIAL PORT
IRING
Connector J5 is the RS232 Serial Port. Kollmorgen offers a pre-made serial communications cable P/N P7S2-
232-D for direct connect to a computers 9-pin serial communications port. The following information is supplied for
applications choosing to not use this cable.
While some computers may vary in the actual pin-out most computers have followed standardizing these
connections. The following diagrams are provided for standard 9 pin and 25 pin Subminiature D-type connectors
provided on most computers. Many HMI/OIT manufactures have chosen to swap pins to allow the cable to be
made pin-for-pin. Always consult the manufacture's recommendations before wiring these types of products.
