Preliminary information
This guide is designed to provide the most complete and exhaustive information the
operator needs to correctly and safely install and operate the ENC58 programmable
incremental encoder.
ENC58 programmable encoder from Datalogic Automation is designed to maximize
customization and versatility and really allows the operator to get, along with the position
information, a complete parametrization and the better configuration that perfectly suit
specific needs in a good many applications and machines.
The operator in fact can not only configure the desired resolution in the range between 1
and 65536 or set the point in the revolution at which the 0 signal is output, but also choose
for instance the voltage level of A, B and 0 output channels between the options 5V and
encoder power supply voltage level.
The parametrization and set up of the ENC58 programmable encoder is achieved through
a software expressly developed and released by Datalogic Automation.
The program is supplied for free and can be installed in any PC fitted with a Windows
operating system (Windows XP or later). It allows the operator to set the working
parameters of the device and monitor whether the device is running properly.
The connection between the encoder and the PC is established by using the USB
connection cable provided by Datalogic Automation.
To make it easier to read and understand the text, this guide is divided into two main
sections.
In the first section some general information concerning the safety, the mechanical
installation and the electrical connection as well as tips for setting up and running properly
and efficiently the unit are provided.
In the second section, entitled Programming Interface, both general and specific
information is given on the programming interface.
In this section the software tool features and the parameters implemented in the unit are
fully described.

4.7 A, B, 0 o u t p u t ch a nn e l s
4.8 Index p u l s e s e tt i n g i n p u t
This encoder provides the zero signal (Index pulse) once per
revolution as relative positioning reference (home position, see the
Figure here above). In this way a unique position can be identified at
a well-known point in the 360° revolution of the encoder shaft.
This input allows to set the point in the revolution at which the 0
pulse will be output. This function is useful, for example, when you
want the zero position of the encoder and the zero mechanical
position of the axis to match.
When you want to set the position of the 0 signal in the revolution
you must send a command via PLC or other controller to the encoder
through the dedicated input. Connect the Index pulse setting input to
0VDC if not used. To set the zero position, connect the Index pulse
setting input to +VDC for 100 µs at least, then disconnect +VDC.
Normally voltage must be at 0VDC or floating.
We suggest moving the axis to the desired position, then activate the
Index pulse setting function while the encoder and the mechanical
assembly are in stop.

WARNING
Please check the position of the 0 pulse and set it if necessary
whenever you set a new resolution next to the Resolution parameter
or reverse the counting direction.
NOTE
The width of the 0 pulse can be set next to the Z pulse width
parameter.
Two options are available: 90° and 180°.
Please note that the 0 pulse having a width of 90 electrical degrees
is synchronised with A and B pulses, while the 0 pulse having a width
of 180 electrical degrees is synchronised with A pulse.
For further information please refer to page 20.
NOTE
It is possible to set the 0 pulse position also by either pressing the
external button located in the rear side of the encoder enclosure -see
the section “ 4.11 Index pulse setting external button (Figure 1)” on
page 12-; or by pressing the PRESET button available in the
programming interface -see the Preset parameter on page 23.
4.9 C ou n t i n g direction i n p u t
By default the phase relationship between A and B channels is so
that the rising edge of A channel leads the rising edge of B channel
when the encoder is rotating in a clockwise direction (see the Figure
in the previous page).
Thus the counter in the subsequent electronics will get a count up.
This input allows to have a count up also when the encoder is
rotating in a counter-clockwise direction (otherwise a count down
when the encoder is rotating in a clockwise direction). Connect the
Counting direction input to 0VDC if not used. Connect the Counting
direction input to 0VDC to have an increasing count when the
encoder is turning clockwise; connect the Counting direction input to
+VDC to have an increasing count when the encoder is turning
counter-clockwise. Clockwise and counter-clockwise directions are
viewed from the shaft side.
WARNING
The counting direction can be set also through the programming tool.
The Direction parameter implies that the Counting direction input is
set to 0VDC. Otherwise the resulting will be contrary to what is
expected or intended. The Direction parameter allows the operator to
choose between the options UP and DOWN. When the counting
direction is set to UP -Direction = UP-, if the Counting direction input
has LOW logic level (0VDC) the encoder will provide the increasing
count when the shaft is turning clockwise (and the decreasing count
when the shaft is turning counter-clockwise); on the contrary if the
counting direction input has HIGH logic level (+VDC) the encoder will
provide the increasing count when the shaft is turning counter-

clockwise (and the decreasing count when the shaft is turning
clockwise).
When the option DOWN is set -Direction = DOWN-, if the Counting
direction input has LOW logic level (0VDC) the encoder will provide
the increasing count when the shaft is turning counter-clockwise (and
the decreasing count when the shaft is turning clockwise); on the
contrary if the Counting direction input has HIGH logic level (+VDC)
the encoder will provide the increasing count when the shaft is
turning clockwise (and the decreasing count when the shaft is turning
counter- clockwise).
WARNING
After having set the new counting direction it is necessary to set also
the Index pulse.
4.10 Diagnostic LEDs (Figure 1)

4.11 Index p u l s e s e tt i n g external b u tt on ( F i g u r e 1)
This encoder provides the zero signal (Index pulse) once per
revolution as relative positioning reference (home position, see the
Figure on page 9).
In this way a unique position can be identified at a well-known point
in the 360° revolution of the encoder shaft. The external button
located in the rear side of the encoder enclosure allows to set the

When you want to set the position of the 0 signal in the revolution
you must move the axis to the desired position, then press the Index
pulse setting button while the encoder and the mechanical assembly
are in stop.
WARNING
Please do not press the Index pulse setting external button when the
encoder configuration interface program is running.
WARNING
Please check the position of the 0 pulse and set it if necessary
whenever you set a new resolution next to the Resolution parameter
or reverse the counting direction.
NOTE
The width of the 0 pulse can be set next to the Z pulse width
parameter. Two options are available: 90° and 180°. Please note that
the 0 pulse having a width of 90 electrical degrees is synchronised
with A and B pulses, while the 0 pulse having a width of 180
