2OVERVIEW
The miniECO comes in two Drive series which differ in performance and price. The miniECO2M range
(code 9XECO2Mxxx) is the entry level range while the miniECO2S range (code 9XECO2Sxxx)
implements all the functions of the previous line plus a further increase in current, additional software
functions, RJ45 connectors for field networks, the STO function, external DC bus, automatic
management of the parking brake, digital feedbacks with BiSS absolute encoder.
Given the high number of functions and parameters, the Drive Watcher software suite
must be used for programming and fine-tuning, while the modification of the individual
parameters can also be done in a simple and interactive way via the local keypad, on-
board the drive. The local display also provides information on the operating status and
any alarms that have been triggered.
This manual only covers in detail the sections on product installation, the relevant
electrical connections, safety requirements and motor set-up. The other functions are
dealt with in a concise manner to allow rapid consultation.

CAUTION: EMC
If an electric drive system (PDS “Power Drive System”) is a component of equipment,
subject to a different EMC product standard, the EMC standard for complete equipment
applies.
The drive is used with other components, such as a motor, transformer, filter, switching
assistance circuit, electrical protection and auxiliary circuits to form a complete final
product. It is the responsibility of the assembler to guarantee that the system or product
complies with all the standards in force in the country where the system or product is used.

4MODELS AND OPTIONS
The miniECO Drive comes in two models: a basic one with an optional encode divider with 3A nominal
RMS 6 A peak RMS (from 1 to 5 sec), the other called miniECO Plus with 4 A nominal RMS and 8 A peak
RMS (from 1 to 5 sec) 230 Vac. Despite its compact size, it contains the cooling fan, which is activated
when the radiator temperature reaches 50°C and deactivated at 40°C, the clamp resistor to discharge
excess voltage during dynamic braking of the motor, the soft start circuit and management of the motor
parking brake. The miniECO Drive features the following operating modes: analog with set-point input
+/-10V, pulse positioner, MODBUS RTU RS 485, S-NET (ESA RS422/RS 485 proprietary fieldbus
network), S-CAN (ESA proprietary fieldbus network with layer 1 and 2 according to the ISO 11898 CAN
standard), PROFIBUS implementable with external GATEWAY, CANOpen (DS 402 Device Profile). Some
inputs assume different functions in different operating modes (analog, pulse, RTU Modbus, CAN, etc.)
depending on the mode chosen via parameter C9. The management of these inputs is defined by
parameter C8 (see the description of parameter C8 in chapter 7).
The miniECO Plus line implements all the line functions previously described and adds other software
functions, RJ45 connectors for the Daisy chain connection in the fieldbus network, STO safety functions,
external DC BUS for energy regeneration management during the motor braking phases, automatic
management of the parking brake, sine/cosine absolute digital feedbacks with BiSS protocol.

4.4 Driven motors
Since the miniECO Drive is totally digital, it uses internal algorithms which predefine the exact
parameterization with which the motor is controlled in order to optimise the performance of the motor
without having to set innumerable parameters. This feature makes it much easier to install the Drive and
considerably reduces the time required to set up the axis dynamics.
It is, therefore, essential to connect it only to the motor with which it will be used. Every Drive model has
been parameterized for use with different factory-set motors which all have a power suited to their drive
capacity, so you should strictly adhere to the Motors table.
The motor effectively used can be selected via parameter “d8” of the configuration file or by the local
keypad.
NOTE: Custom motors
For some requirements, it is possible to use other motors or the same motors but with a
different mapping. To this end, the mapping can be customised up to a maximum of 10
motors or 10 mappings by using a specific program called “Motor SET-UP”.

5MECHANICAL INSTALLATION AND DIMENSIONS
CAUTION:
All the mechanical dimensions of the miniECO series (Standard or Plus) are the same, so
all the tables, which refer to the miniECO2M, are also correct for miniECO Plus
•Check that the packaging is intact in the original box and that the Drive, its connector kit and the
possible spare resistor have not incurred any visible damage during transportation. Otherwise,
do NOT connect the Drive and do NOT use the other components under any circumstances.
•The Drive is intended to be used in fixed systems and NOT on moving surfaces. If it is necessary
to assemble it on surfaces with strong vibrations, suitable measures must be implemented, e.g.
anti-vibration supports.
•The Drive is configured to be mechanically secured to the anchoring surface of an electrical
panel via the specific fastening holes on the external housing.
To allow for correct ventilation, it should be positioned vertically so that air can circulate naturally
between the dissipator fins. If it is necessary to install it horizontally (horizontal assembly panel), for
reasons of space, it will be necessary to provide forced ventilation or downgrade the performance.
CAUTION: ELECTRICAL SAFETY
To avoid drive malfunctions, the installation must carefully observe the following
precautions when positioning it inside the electrical panel:
1. Install it in clean environments, free from dust or corrosive agents and with low
humidity.
2. Do not install it near heat sources, such as transformers, etc. and do not, in any
case, place it on top of these sources to avoid overheating.
3. Make sure that the ventilation (under the Drive) and aeration slots (on the Drive)
are not blocked in any way.
4. Leave a gap on all sides of at least 20 mm clear of the components.
5. Install it on a support surface consisting of a single metal plate (uncoated).

5.1 Mechanical dimensions
5.1.1 miniECO Standard –9XECO2M0306
5.1.2 miniECO Plus –9XECO2S0408

5.2 Braking resistor
All the models of the minECO drive have an internal braking resistor. MiniECO Plus also has an internal
braking resistor, but it is, however, possible to connect an external resistor to an M2 terminal block. The
internal brake resistors supplied with the drives are 100Ω 100W. There may be applications with
particularly demanding cycles which, when associated with a high inertia load, do not allow the resistor
supplied to dissipate all the energy required. When this happens, an external resistor with a suitable power
must be connected to pins 1 and 2 of the M2 terminal block.
CAUTION:
The braking resistor can get very hot due to the inertia load and machine cycle. So, when
mounted externally, the braking resistor must be segregated in a part of the electrical panel
which does not pose a risk for nearby equipment or for the wiring. In some cases, when a
high inertia load is associated with an extremely short machine cycle, mechanical
segregation with thermal alarm protection becomes essential.
The dissipated power can be calculated with the following formula
P= (0.5 × J t × ω2 × f) –PL
where
Jt = total inertia [in Kg m2]
ω= max angular velocity [in rad/sec]
f = repetition frequency of the work cycle [no. of cycles per second]
PL= power needed to overcome friction.

6ELECTRICAL INSTALLATION
Since the drive is digitally controlled, it must be coupled to the motor for which it has been configured.
Consequently, it is essential to ensure that this is done with great care. Check the correct pairing of the
d8 parameter, therefore, in the motors table.
If a motor with a different model is connected, problems may arise, such as instability, overheating and a
drop in performance.
DANGER HIGH VOLTAGE
Different parts of the product have high voltage which may constitute a serious risk for
safety of personnel. Do not touch exposed connections when the power supply is
connected. Always disconnect the power and wait 5 minutes before carrying out any work
on the connections or accessing the internal parts.
Installation must be carried out by qualified technicians who have considerable
knowledge of the source of risks involved and relevant safety and accident-prevention
regulations to observe.
It is the user’s responsibility to ensure that the installation is compliant with the safety
provisions currently in force.
The device must be connected to a suitable grounding. Failure to implement this
connection entails risk of electric shock.
6.1 Description of electrical connections
The drive has terminal blocks and connectors located on the front of the housing. These connections are
shown in the figure. The miniECO Plus series version has the same terminal blocks and connectors as the
miniECO Standard series, except for the mini-din and so, the common connections described below can
be used for all the models. The additional hardware functions for the miniECO Plus have extra
connectors which are explained in the footnotes at the end of this manual.

6.2.1.1 Power supply
1. Use terminals L1-L2 for the single-phase phase-neutral connection.
2. For the single-phase phase-neutral power supply, with neutral connected to earth, a fuse on the
phase power cable is sufficient.
CAUTION:
The shield must be grounded using a metal cable gland as close as
possible to the two ends of the cable. The panel must be paint-free in the
area underneath it. If it is not possible to connect the cable gland near the
drive, the sheath wire can be taken to the ground terminal.

6.2.1.2 Power supply signals
IMPORTANT:
The ground wire of the devices connected to the serial and/or parallel communication
ports must be at the same potential as the 0V power supply of the miniECO. The
circulation of a current between the 0V power supply and ground wire of the
communication ports could damage some components of the miniECO or devices
connected to it. The power connector (female) is the way in which the appliance can be
disconnected from the power source. Install the device so that the connector can be easily
accessed.
6.2.2 Description of miniECO Plus M2 terminal block signals: External DC-BUS and braking
resistor
3-pole-type terminal block connector, on the bottom of the drive that allows you to wire a system that
uses the energy regenerated by the electronic braking of the motors and use it (if the cycle allows it) for
other Drives, thus limiting heat dissipation on the braking resistors. This use allows different drives to be
connected to together (max 4) as if you were using a modular system. The Drives must have similar
powers. The connection must be done between the DC+ and DC- terminals
6.2.3 Connections on terminal block/connector on the MOTOR side
The connections on the motor terminal block have different names depending on the types of motors
used. The following table shows the different names and associates the Drive signal name with the
motor terminal.
