Manual purpose
This manual has been designed by the manufacturer to provide the necessary information regarding the
SERVO unit to those who are authorized to carry out safely its installation, maintenance, removal and
disposal. All the necessary information for the buyers and planners can be found in the sales documentation.
In addition to adopting good technical construction methods, the information should be read carefully and
strictly applied. Inobservance of this information could cause risks for the health and safety of people and
equipment damage. This information, provided by the manufacturer in the original language (Italian) is also
available in other languages to satisfy legislative and/or commercial needs. A responsible person must keep
this manual in an ideal place in good conditions so that it is always available for consultation. In case this
manual is lost or deteriorates, a replacement should be requested directly from the manufacturer indicating
the product part number. This manual reflects the features of the instrument at the time of input on the
market: however the manufacturer reserves the right to make changes, add or improve the manual without
giving any reason to hold the present manual inadequate.

Description
The SERVO.M positioning unit comprises a DC geared motor with microprocessor control of the drive gear
and an incremental position transducer (encoder) or absolute position transducer (precision potentiometer)
connected to the output shaft with interface for field bus and display with 5 digits. It creates, in a single
compact device, a complete system for axis control axis where the position to reach is communicated by bus
and a PID type controller is present. The SERVO.M-E version has a position transducer with an incremental
optical encoder, while the SERVO.M.P version has a precision potentiometer.
The SERVO.M unit has a hollow shaft output to enable a simple installation and a versatile use, even with
pre-existing manual motion machines that must be automated. Therefore it is suitable for a large number of
applications on machinery within industries such as printing, packaging, woodworking, marble, plastic, etc. A
simple linking and lay out are guaranteed by a supervisor (PC, PLC), the system interfaces with a bus-field to
control the positioning and enable the modifications of the control parameters (present value, speed, state).
The communication protocol can be MODBUS RTU, CANopen, PROFIBUS DP.
For electrical connection, the power-supply cable and the communications cables are separate: the standard
version of the SERVO.3M has 3 cable glands for input and output (2x PG9, 1x PG7); an M12-T connector is
available as option for power instead of the PG7 cable gland.
Installation
Before installing the instrument, read the following warnings:
a) Connect the instrument strictly following the instructions of the manual.
b) Carry out the connections using the correct wires within the limits of the tension and power supply as
indicated in the technical data.
c) The instrument does not have an ON/OFF switch, hence it comes on when connected to the power supply.
For safety reasons, the equipment connected permanently to the power supply requires a bi-phase selector
switch which should be within easy reach of the operator.
d) If the instrument is connected to any apparatus not isolated electrically, carry out an earth connection to
avoid it being connected directly through the structure of the machine.
e) It is the responsibility of the user to check, before using, the correct settings of the parameters of the
instrument to avoid damage to persons or equipment.
f) The instrument cannot function in a dangerous environment (inflammable or explosive). It can be
connected to elements that operate in the same atmosphere only through appropriate interfaces, according
to the current safety regulations.
g) Avoid dust, humidity, corrosive gases, heat sources.

Power supply
a) Before connecting the unit, check that the power supply tension is within the permitted limits and that it
corresponds to the one indicated on the tag.
b) Carry out the electrical connections with the instrument disconnected.
c) For the power line to instruments and sensors, a power supply line separate from that of the power is
required : it is necessary to use an isolating transformer.
d) The power line should provide a device that separates the set fuses of the instruments and should not be
used to regulate relays, contactors, etc.
e) If the network tension is very disordered (ex. from the change-over of the power units, motors, inverters,
welders, etc.), use the appropriate filters of the network.
f) If an earth connection is needed, ensure that the plant has an adequate grounding system: tension
between neutral and earth <1V and the resistance <6 Ohm.
Gear motor assembly
Two M4 screws can be applied to the two M4x12 brass inserts: this is necessary in case the servo motor
must make many maneuvers or is used continuously.
The diameter Ø20 millimeter (50mm deep) hollow shaft is applied to the driving shaft of the machine.
Ensure that the hollow shaft is perpendicular to the support base.
Lock the hollow shaft onto the machine shaft using the M4 screw on the clamping ring.
Note: The gear motor does not have parts that need maintenance or oiling.
If necessary, protect the unit from: dust, water, collisions, extreme temperatures.
Manually turn the shaft of the reducer using the clamping ring (tightened on the hollow shaft)
only if necessary.
Do not exceed permitted torque.
Do not dismantle or open the unit, particularly the part of the reducer.
Do not pierce/modify the container or the hollow shaft.
POTENTIOMETRIC VERSION Before assembling the SERVO, it is fundamental to place the shaft of the
machine and the shaft of the SERVO in the correct position, for example half way or towards the end, in a
way that there is correlation between the position of the SERVO and that of the machine. To do that, the
motion of the hollow shaft of the SERVO should be serially commanded by the control unit (PLC, PC, etc): do
not rotate the shaft by hand.
The calculation of the number of turns that the hollow shaft has to complete to achieve the total motion of the
machine is determined by multiplying the reduction ratio of the reducer of the potentiometer by the number of
turns of the potentiometer itself (total reduction ratio = R).
In case that the maximum number of allowed rotations by the shaft is exceeded, a mechanical clutch
intervenes to safeguard the potentiometer transducer.
Note: the SERVO is provided with the hollow shaft and the potentiometer positioned half way.
ELECTRICAL CONNECTION
Disconnect from power supply before connecting/disconnecting the equipment/machinery.
The connecting cables must be kept separate from the power lines or from electromagnetic
interference sources.
Pay careful attention to the electrical connections: any failure caused by a faulty connection
will render the guarantee null and void.
The power supply must be in the permitted range, a higher range could damage the
equipment.
Remove the 3 closing screws of the cover to access the terminal box.
Carry out the connections according to the following figure:

SETTINGS OF ADDRESS AND BAUD RATE
Before setting SERVO it is necessary to set the address and baud rate of device using dip-switch S1 and S2
as showed in the following table according to the model of SERVO used.
If the SERVO is the last node of net, set at ON the dip-switch S3 (both switches 1 and 2 at ON).
IMPORTANT: during this phase it is advisable to pay close attention to not damage the dip-switch and the
electronic components on the board. It is strictly forbidden to take off the card of its case.
Assemble the wiring clip jumper to assure the continuity of shield mostly for the Profibus cables.

Setting of device address and serial communication speed – MODBUS protocol
The setting of baud rate is made by the dip-switch S1 (set in factory at 19200) and that of the address with
dip-switch S2 (se in factory at 1). Valid addresses are from 1 to 247.
By changing of address or baud rate is necessary to switch off and turn on the Servo.
Setting of device address – PROFIBUS protocol
The setting of address is made by dip-switch S2 (set at factory at 1). Valid addresses from 1 to 127. The
speed is measured automatically.
Setting of device address – CANopen protocol
The setting of address is made by dip-switch 1-7 of S2. Valid addresses from 1 to 127.
The setting of baud rate is made by il dip-switch 8 di S2 and the 2 dip-switch of S1.
By changing of address or baud rate is necessary to switch off and turn on the Servo.
