Description
The positioning unit SERVO.D is made of a geared brushless motor in direct current with microprocessor
control of the driving gear and of an absolute (precision potentiometer) assembled on the output shaft with
interface for field bus. It realises in a single and compact device a complete system for the control of axis
being able to receive by bus a dimension to reach and start with the positioning by a control type PID.
The SERVO.D unit has a hollow shaft output to enable a simple assembling and a versatile use, even with
pre-existent manual motion machines that have to be automated. Therefore it is suitable for a large number
of applications in machinery within industries such as printing, packaging, woodworking,
marble, plastic, etc. A simple linking and layout 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 quota, speed, state).
The communication record can be MODBUS RTU, CANopen, PROFIBUS DP.
The electric connection is made by the means of 3 connectors M12x1 for power supply and field bus.
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 things.
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.
