DULLANT DT760 Series User Manual

User's Guide for DT760 series high-performance vector inverter
Thank you for choosing DULLANTI's DT760 series high-performance vector inverter.
Document No.: 31010200
Release time: 2022-3
Version: 200
The DT760 series inverter is a high-performance vector control inverter launched by DULLANT, which
integrates the synchronous motor drive and asynchronous motor drive. It supports three-phase AC asynchronous
motors and permanent magnet synchronous motors, internationally advanced drive control technologies [such as
the improved vector V/F control technology (VVF), speed sensorless vector control technology (SVC) and speed
sensor vector control technology (FVC)], speed output and torque output, Wi-Fi access and background software
debugging, expansions (such as I/O expansion cards, communication bus expansion cards and PG cards). The
standard DT 760 supports V/F control, SVC control, FVC control of asynchronous motors; it also supports V/F
control and FVC control of permanent magnet synchronous motors. The non-standard version for synchronous
motors also supports V/F control, SVC control, FVC control of asynchronous motors, as well as V/F control,
SVC control and FVC control of permanent magnet synchronous motors.
The DT760 series high-performance vector inverter has the following features:
 Equipment of a built-in DC reactor (in case of an inverter of above 18.5kW) can reduce input current
distortion, increase the power factor and promote the product reliability;
 High torque control accuracy: SVC/±5% rated torque, FVC/±3% rated torque;

Wide speed range and high control accuracy

Low-frequency carrier: VVF/3Hz/150%, SVC/0.25Hz/150%, FVC/0Hz/180%;
 Protections against overvoltage stall, fast current limit, overload, overheat, off-load, overspeed, and so on;
 Support I/O expansion: 3-channel digital inputs, 2-channel relay outputs, 1-channel -10V~10V voltage
input, 1-channel sensor input;

Support communication bus expansion: standard configuration including 485 bus, optional PROFINET,
CANopen and EtherCAT;
 Support various encoders: ABZ incremental, UVW incremental, UVW wire saver, rotary transformer and
sine-cosine transformer;

Support debugging by the mobile phone APP or monitoring of the inverter status;
 Support Wi-Fi module or serial port access;
 Rich and convenient PC background software functions.
Before using the DT760 series high-performance vector inverter, please read this guide carefully and
keep it properly.
