3General Description
3.1 DUET AD
The DUET AD represents EC-motors (brushless DC motor) with an integrated torque, speed, position
control electronic and a 14 bit single-turn absolute encoder.
The desired command can be set via analogue signal input 0 ... +10 V. The four operating modes
“clockwise rotation”, “counter clockwise rotation”, “Off” (rapid break- point with freewheel) and “Stop”
(rapid breakpoint with holding torque) are controlled via the two digital inputs IN0 and IN1. Optional, two
further digital inputs for additional functions are available. Therewith, among other things, 2 fixed motor
speeds (e.g. for rapid movement and creep speed), acceleration ramp and braking ramp can be memorized
on the device EEPROM. Two digital output signals are available additionally: one giving
12 pulses per turn (e.g. for position and speed control), the other showing “fault”.
Additionally, the device con be operated via Modbus RTU or CAN Open (only available on CAN Model)

DUET AD Installation Guide Pag. 5
By means of the integrated absolute single-turn encoder with a resolution 16384 increments per revolution,
a very high positioning accuracy with very good regulating characteristics can be achieved.
In case of larger needs, customer specific solutions with special firmware are available on request.
The DUET AD has except of the ball bearings no expendable parts and is hence excellently suited for
continuous operation. The motors Device can be combined with planetary or worm gears with a multitude
of gear ratios.

Motor Power Company.
The Device may only be put into operation once the entire system has been installed in accordance with
EMC. Please follow the instructions in chapter 7.2.
3.3 Standards and guidelines
EU guidelines: the EU guidelines formulate the minimum requirements made on a product and must be
observed by all manufacturers and dealers marketing the product in the member states of the European
Union.
Machine guideline: the device is a machine in the sense of the EU guideline for machinery. It has
moveable parts in accordance with its intended purpose: however, it may only be installed as a component
of a machine or a system. The advice described in these instructions regarding installation and operation
must be adhered to.
EMC guideline: the EU guidelines for EMC apply to devices which can cause electromagnetic interruptions
or whose operation can be impaired by these interruptions. Compliance of the drive with the EMC guideline

DUET AD Installation Guide Pag. 6
can only be tested once it has been installed. The information pertaining to EMC described in these
instructions must be adhered to.
Conformity: by means of the conformity declaration of the product (see appendix), Motor Power
Company confirms that the device complies with the safety standards listed therein and with EMC
standards. The product may be sold and used within the European Union.
4Safety instructions
Warning:
Before commissioning, it is essential that the safety instructions in the relevant
section are read and understood, and then observed!
Non-observance can result in danger to persons or damage to the equipment.
►Disconnect the electrical power supply before any operation on
the device!
NOTICE:
The drive must only be installed and adjusted by qualified persons in
accordance with the relevant standards.
Qualified persons are those who:
►based on their experience, can recognize and avoid potential dangers.
►are familiar with the accident prevention regulations for the equipment
deployed.
►can connect circuits and install equipment in accordance with the
standards and regulations.
NOTICE:
To ensure trouble-free operation, appropriate methods of transport and
conditions of storage must be deployed.
Please store the drive so that it is protected from:
►dust, dirt and moisture
Take care also at the storage conditions:
►e.g. storage temperature!
(See technical data)
Transport the drive under storage conditions
►protection against shock

6Protective functions
6.1 Ballast circuit
During braking operations, kinetic energy is stored as electrical energy in an intermediate part of the
regulation circuit. This can cause excessive voltage in the intermediate circuit, which, in an extreme case,
could cause damage to electrical components. To prevent this, a DC-power supply should be used which
has a bridge rectifier and a smoothing capacitor of at least 1000 µF per 1 A nominal motor current.
In addition, an external ballast resistor (drop resistor) is necessary.
Motor Power Company recommends a resistor of 4,7Ω .
The ballast resistor must be defined depending on the braking power (at least 50watts). It is necessary to
use a fuse of 6,3AT against overloading of the ballast resistor.
The ballast circuit switches on at 52V and off at 50V device voltage. It does only work and protect the
device (and supply) if the ballast resistor is connected like shown in chapter 8.1 / 8.2.
According to standard, Motor Power Company offers the braking resistor (must be ordered separately).
005016001114 RESISTENZA DI FRENATURA 200W 4,7OHM HSC2004R7J
005016001116 RESISTENZA DI FRENATURA 500W 4,7OHM RS PRO
6.2 Current limitation
To protect the motor against overloading, the motor current (phase current) will be supervised from a I2t
protective function and will be limited (if necessary).
