Functional Overview General
Figure 3.1 provides an overview of the major blocks associated with the
control functions of the Bulletin 1395. All control functions in the 1395
are performed through the use of parameters which can be changed with a
Programming Terminal.
Feedback information is derived from hardware devices as shown on the
right side of Figure 3.1. Analog signals are converted to digital signals for
use by the drive. Control signals may be provided to the drive from up to
two optional Adapter Boards.
All setup and operation information used by the drive is stored in a system
parameter table. Every parameter including Setup and Configuration
parameters (Sources and Sinks) has an entry in the parameter table. For
example, Parameter 154 is named the “Vel Ref Whole” parameter and
contains a number representing the velocity reference. The velocity
reference can originate from an external control device such as a
potentiometer connected to the Discrete Adapter Board or a signal coming
from a PLC.
