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 configuration, functionality control takes place via the most
advanced fieldbus 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 configuration).
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 100
μ
s 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 confirm 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.
