Parameter Table
Introduction This chapter contains materials intended to provide an easy reference
condensed table of all configuration parameters and their specified
uses.
Terminology Configuration – The process of linking Sink to Source Parameters.
For a description of configuration, refer to Chapter 5 in this manual.
Configuration Parameters – Parameters used to transfer data
between the Drive control and external devices. The Configuration
Parameters are categorized into two types:
1. Source Parameters
2. Sink Parameters
Drive Units – The actual value of the parameter as it is stored within
the Drive Parameter table. The Drive units may be converted to
engineering units or to hexadecimal for display using the
Programming Terminal, or may be displayed directly in Drive units.
All internal values in the Drive are in terms of Per Unit numbering.
Engineering Units – A label given to parameter data which specifies
what units are to be used to display the parameter value on the
Programming Terminal. Examples of engineering units include:
RPM, % etc.
Fast Parameter – Fast parameters are all parameters whose values
are updated every 1 millisecond. Fast parameters are used for the real
time data input and output of the Drive. Fast parameters are NOT
backed up in nonvolatile memory.
Non-Volatile Memory – Data memory in the Drive which retains the
values of all data even when power is disconnected from the Drive
control. EEPROM (Electrically Erasable Programmable Read Only
Memory) chips are used for the 1395 nonvolatile memory to store
some of the Drive parameters.
Parameter Table – Table of parameter entries for all Configuration
parameters used in the Drive.
Parameter Entry – Information stored in the Drive which contains
the parameter number, parameter data and all other information
related to the specific parameter.
