Element Quan-
tity ID Description
Logical axis 1 1* A logical axis represents the motion of the mechan-
ics in E-871.1A1N's firmware. It corresponds to the
axis of a linear coordinate system. Motion for logi-
cal axes is commanded in the firmware of the
E-871.1A1N (i.e., for the directions of motion of a
positioner).
The axis identifier can be queried with the
SAI?
command and modified with the SAI command. It
can consist of up to 8 characters; valid characters
are:
1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ-_
The positioner type connected to an axis can be
queried with the
CST? command. If the Stage Name
parameter (0x3C) has the value NOSTAGE, the axis
is "deactivated". A deactivated axis is not accessible
for axis-related commands (e.g., motion commands
or position queries). The identifier of a deactivated
axis can only be queried with
SAI? ALL .
Analog inputs 8 1 to 8 The analog input lines with the identifiers 1 to 4 are
the inputs 1 to 4 of the
I/O socket. Their number is
displayed with the TAC? command and their values
can be queried with the TAV? command. Note that
these lines can also be used as digital inputs (see
below).
Additional analog input lines are located at the
Joy-
stick socket. These lines are not output via
TAC?
and
TAV?
.
The values of all inputs can be recorded via record
option 81 of the
DRC command.
For information, see: Analog Input Signals (p. 84)
Digital outputs 4 1 to 4 1 to 4 identify digital output lines 1 to 4 of the I/O
socket.
For information, see:
Digital Output Signals (p. 76)
Digital inputs 4 1 to 4 1 to 4 identify digital input lines 1 to 4 of the
I/O
socket, which can also be used as analog inputs (see
above).
For information, see:
Digital Input Signals (p. 80)
HID (Human In-
terface Device) 1 1 The HID (e.g., joystick) is used for HID control of the
E-871.1A1N's logical axis. Information on the HID's
axes and buttons can be queried with the
HIS?
command.
For information, see:
Controlling with an
HID (p. 85)
HID axes 4 1 to 4 Two of the HID's axes can be connected to the
Joy-
stick socket. Connection options:
■
Pin 4 (0 to 3.3 V): Command as axis 1 of the HID
■ Pin 2 (0 to 3.3 V): Command as axis 2 of the HID
