Database file name
Description
PISTAGES3.DB
Delivery includes parameter sets for all standard positioners
from PI and PI miCos, and is saved to the PC automatically
during installation of the PC software. New parameter sets
can be created, edited, and saved.
Product code.db
Includes the parameter set for the custom positioner "prod-
uct code". In order for the parameter set to be selectable in
the PC software, it must be imported into PISTAGES3.DB first.
The positioner database only contains some of the information that is required to operate a
positioner with the E-871.1A1N. When the the positioner connected to the E-871.1A1N is
equipped with an ID chip: Further information is loaded as parameter values from the ID chip
to the volatile memory of the E-871.1A1N when the E-871.1A1N is switched on or rebooted.

ID Chip Detection
PI positioners with DC motor have an ID chip in the connector where the following data is
stored as parameters:
■
Information on the positioner: Type, serial number, date of manufacture, version of the
hardware
■
Signal type output by the position sensor
The data of the connected positioner is loaded from the ID chip into the volatile memory of
the E-871.1A1N when the E-871.1A1N is switched on or rebooted.
The ID chip only contains some of the information that is required to operate the positioner
with the E-871.1A1N. When you use the PC software from PI, further information is loaded as
parameter values from a positioner database into the volatile memory of the E-871.1A1N.
The parameter values in the E-871.1A1N's volatile memory can be queried and written to the
nonvolatile memory (see:
).

Block Diagram
The E-871.1A1N controls the motion of a positioner's logical axis. The following block
diagram shows how the E-871.1A1N generates the piezo voltage for the axis connected:
