Parameter SetĆUp Description
After hard wiring the I/O to the Discrete Adapter board terminals, you
must set up parameters in the drive using the Program Terminal to allow
for data flow between the Discrete board and the drive. As was shown in
Figure 4.4, each terminal has parameters associated with it. Set-Up
parameters are used to program the Adapter board functions, and consist of
Parameters 550 through 559 for Port A, and 500 through 549 for Port B.
Configuration parameters allow the Discrete adapter to communicate with
the Drive, and must be linked to a parameter in the drive (refer to the 1395
Installation and Maintenance Manual and read the description of
configuration links). Which Configuration parameters are used, is also
dependent on which adapter port you use. Configuration parameters in the
400 series are used with Port A, and Configuration parameters in the 300
series are used with Port B. A detailed description of these parameters is
provided in Chapter 8, Control Description, of this manual.
Each Set-Up parameter associated with a specific input/output is used to
define the device connected to that input/output. Often there is more than
one Set-Up parameter associated with the I/O. Analog inputs and outputs
require two for scaling and offset of the value.
Figure 5.1 shows the
parameters required for each I/O device used.
To use this board with the Bulletin 1395, you must link the Configuration
parameters to the proper parameter in the drive. This sets up the LINK files
so that during run-time operation the proper parameters are transferred to
and from the Discrete Adapter Board.
Example StartĆUp Configuration
The following is provided as an example of start-up configuration of the
(Linking)
Discrete Adapter Board: Your actual configuration is dependent upon
specific application requirements.
In Figure 5.1 the Discrete Adapter board is connected to Port A of the 1395
Drive. All external wiring to the Discrete Adapter board will be terminated
at terminal block TB3 located on the bottom of the drive. Because the
adapter is connected to Port A, the 400 series configuration parameters are
used to communicate information to/from the drive.
The configuration shown provides the following setup:
S The digital inputs are connected to source parameter 400, which in turn
is linked to parameter 151 (logic command 2). When a digital input
changes state, this information will be transferred directly to Logic
command 2 via parameter 400. Parameters 583 through 586 specify
which bit of Parameter 400 (and thus 151) will be effected by each
digital input.
