Ch. 1 Safety Informations
Read carefully this manual before using NTT 240/460 drive.
Take care of this handbook and keep it at hand for later reference.
Please make sure that this handbook is delivered to the nal customer and user.
Safety symbols used in this guide are described below:
DANGER:
This symbol means the possibility of serious body hazards due to
electrical, thermal or mechanical shock.
!
ATTENTION/WARNING:
This symbol means the possibility of damaging drive or other
equipment.
!
NOTES:
This symbol suggests auxiliary informations to ensure a correct
operation for drive or other equipment.
1.01 Danger
• Never supply the drive without the cover and never remove the cover while supply is on.
• Do not manipulate the drive with wet hands. Failure to observe this could lead to electrical shocks.
• Keep a safety distance from the motor and the machine when the power is on and never touch the rotary parts
of the motor when it is in function.
• When reset the alarms make sure that the signal of running is enabled in order to avoid unexpected start of the
motor. Fix up a separate emergency stop device. It exists the risk of injury.
• Do not touch the terminals of the drive, the motor or the external braking resistance, while the power is on.
Failure to observe this could lead to electrical or thermal shocks.
• Before starting wiring, ensure that all supplies are o and motor is stopped.
• Always turn the device’s input o before starting any maintenance. Failure to observe this could lead to res or
electrical shocks.
• Disconnect all supplies before performing drive maintenance.
• Always wait at least 8 minutes after turning o the input power before starting inspections. Make sure that LEDs
have been erased.Failure to observe this could lead to electrical shock.
• The maintenance, the inspection and part replacement must be done by a designated person. Remove all the
metal accessories like watches, bracelets etc before beginning the job. Failure to observe this could lead to
electrical shocks and injuries.
• Always turn the power o before inspecting the motor or machine. A potential is applied on the motor terminal
even when the motor is stopped. Failure to observe this could lead to electrical shock.
• Ensure that supply voltage range mathes with drive features.

Rev: 4.0
NTT 240/460 Safety Informations
1.02 Attention
• Earth cable must be wired according to safety standards of the Country where drive is installed.
• Installation must be done by a designated person.
• Always x the drive before executing the wiring.
• Install a protection circuit (fuses or magnetic contactor) on drive supply.
• Do not connect an esternal supply on terminals U, V, W.
• Ensure that the drive voltage correspond to the voltage of the supply.
• Fix terminal screws with a correct xing torque.
• Connect correctly the output side (U,V,W). Failure to do so could cause the motor to rotate in reverse and the
machine to be damage.
• If drive power supply is not connected, not connect motor cable if motor is rotating. It exists the danger to
damage the machine.
• Not obstruct the entry and the escape of the air and not introduce stranger object. Fire danger exists.
• Ensure the functionality of the motor as single unit before connecting it mechanically to the machine and verify
that the max speed of the motor are accepted from the machine. It exists the danger to hurt and to damage the
machine.
• Never modify the drive.
• Clean the drive with a vacuum cleaner. Do not use organic solvents. Failure to observe this could lead to burns
or damage.
• For your safety, it is very important that any software update or service have to be done by our company.
• When you have to throw away the drive, please dispose of this product as industrial waste, so respect standards
enforced by Country laws.
1.03 Notes
• Qualied electrical sta must execute installation and maintenance.
• Earth cable must be wired according to safety standards of the Country where drive is installed.
• The machine operator must receive an adapt preparation.
• The drive may be source of radio-frequency noise if unprovided of the adequate mains lter.
• Observe the drive speciations and the warnings contained in this manual.
• Always provide an adequate ventilation and keep clean the drive.
• Avoid water or other liquid penetration inside the drive.
• Connect adequate cable to the imput/output terminals.
• Product in C2 cat. may be source of radio-frequency noise if used in public mains feeding voltage to habitation.
• Product in C3 cat. is not suitable in public mains feeding voltage to habitation. The drive may be source of radio-
frequency noise.

Ch. 2 Introduction
2.01 Description
NTT 240/460 digital servodrives replace the well known previous DGM series. The evolution
version incorporates a last generation microcontroller that provides a doubled calculation
performance, a quadruplicated analog to digital converter accuracy, resulting in an evolution for
motor control and software application.
According to drive selected conguration, functionality control takes place via the most
advanced eldbus comunication protocols, including ETHERCAT CoE, PROFINET RT, PROFIBUS,
Canopen® and Modbus RTU, as well as the Input/Output operating mode (always available in
each drive conguration).
It allows control for AC and DC Brushless motors, type rotary, linear and tubular, asynchronous
motors and permanent magnets continuous current motors equipped with HALL sensors, incremental encoder with
or without HALL sensors, absolute encoder on SSI serial protocol and resolver (optional), for position and speed
feedback. An AC power supply, 230Vac singlephase or triphase and 400Vac triphase, or DC power supply from 250V
to 360V for NTT 240 and from 400V to 700V for NTT 460, is requested for power stage and a second DC logic supply
is requested for turning on the drive.
NTT 240/460 can be set up with property software, Caliper, (compatible with Microsoft Windows® operative systems),
that allows to enter all calibration settings, parameters saving and alarm management and, thanks to USB 2.0
comunication, to perform debug with realtime scope up to 100μs on 4 simultaneous channels.
Head-on display allows to check drive state and to verify alarms/warnings, leading to a fast failure diagnostic.
2.02 Delivery ispection
For delivery ispection and storage:
1. Remove drive from the packaging and check details on the label that conrm the drive correspond to the
one ordered. The label in on the heatsink side.
2. Make sure that the product has not been damaged.
3. If the drive is not to be used for a while after purchasing, it has to be stored, possibly with its shipment
covering, in a place with no humidity, absence of vibrations and far from water sprays.
4. Always inspect the inverter before using after a long period storage.

Ch. 3 Installation
3.01 Mechanical installation
Please follow the following instruction during the installation:
1. Install the drive in a vertical and perpendicular position regarding the oor.
2. Insure yourself that the environment temperature is comprised between 0 and 40° Celsius.
3. Avoid the following conditions:
• Direct exposure to the solar light
• Assemble in places with presence of powders, soil, particles of iron.
• Assemble in places with corrosive gas, explosive gas or high grade of humidity.
• Assemble in proximity of machines that generate vibrations.
• Assemble in proximity or on inammable matter (as wood) or not resistant to the heat.
4. Insure yourself that the driver will be assembled in a position that guarantee a correct ventilation, as shown
in picture below.
