Programming Parameters
Introduction This chapter contains the information required to assist the user in
programming the drive for a specific application after initial start-up.
Drives are shipped programmed with default values and are
preconfigured for the options installed.
The drive parameters can be divided into the following categories:
Basic – The Basic parameters that must be programmed at the time of
start-up.
Setup – The Setup parameters are default values that may require
changing during start-up.
Speed Reference – The Speed Reference parameters are used as speed
reference sources for the drive.
Input – The Input parameters accept information from sources outside
the drive.
Autotune – The Autotune parameters are automatically set by the drive
control during start-up. Occasionally, they may require modification by
the user.
Status – The Status parameters provide information about the drive and
its operation.
Terminology The definition of terms related to the parameter table include:
Configuration – The process of linking Sink to Source parameters.
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 – Fast parameter used as a source of data.
2. Sink Parameters – Fast parameter used to receive data input.
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 hexidecimal 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 2 milliseconds. Fast parameters are used for the real time
data input and output of the drive. Fast parameters are NOT backed up
in non-volatile memory.
