The professional servodrive.
NTT240 servo drives for 230VAC networks, flexible and powerful but also simple to use.
They guarantee the best control for brushless, continuous and asynchronous motors and perfect realtime connectivity with PLC and motion controllers.
Give the best to your applications.
Dedicated to 230VAC.
The versatility of NTT also accompanies you in applications for 230VAC networks with the NTT240 version. Top performance for nominal powers up to 3kW and for a nominal current of 10A. Mains filter and braking resistor are internal and if you want you can take advantage of the regenerative effect between multiple NTT240 drives connected together through the DC Bus.
Change to NTT!
Not just brushless.
But also DC motors with permanent magnets equipped with encoders.
But not only. It also perfectly controls the asynchronous motor both in Volt/Hertz and in FOC.
Useful for controlling spindle motors.
But it's not over. It also controls linear brushless motors with linear encoders.
A truly unique drive with incredible flexibility.
In line with tradition.
An analog input +/- 10V differential at 16Bit for the main speed reference, torque or to detect a pressure signal.
Two 12Bit +/- 10V auxiliary analogue inputs suitable both as speed reference, torque limit or position.
The most used in Asia.
A frequency input up to 2MHz per channel can be used as a speed / position reference in "pulse/direction" or CW/CCW modes based on the input signal from the PLC.
The same input also manages an external A/B incremental encoder feedback.
NTT allows great flexibility also in terms of communication. Alongside the traditional analogue inputs it is possible to configure NTT with the most important, fast and versatile field buses available on the market to be able to interact with any PLC, motion cotroller and CN in the market and related peripherals.
Input and Output.
NTT is equipped with both analogue and digital inputs and outputs that can be programmed for greater flexibility through the Caliper software.
Analog inputs and outputs.
Three differential analog inputs at 16 Bit and 12 Bit.
Two programmable analogue outputs..
Digital inputs and outputs.
11 PNP inputs programmable between optoisolated and non optoisolated and 6 programmable optoisolated PNP outputs.
A programmable relay contact and a frequency input.
Connectors with spring coupling, stop to screw or solder connectors.
Easier to wire than a solder connector.
More reliable and safer than a screw-on connector.
Because your time is precious.
A focus on spare parts.
The spring connector makes it easier to replace the old DGM servo drive equipped with a 44-pin solder connector. HDT scrupulously takes care of the compatibility aspect with previous models.
Because the satisfaction of your customers is also our satisfaction.
The double of before.
Two standard inputs and one optional for reading position transducers.
The main input for reading Incremental Encoders with Hall or absolute digital encoder with SSI, BiSS, Endat protocols, up to 32Bit/turn, 16Bit/multi, both rotative and linear.
The second input dedicated to reading an external auxiliary incremental encoder positioned on the application, rotative or linear.
The third, optional, for reading Resolvers with 16Bit resolution or absolute encoders type SSI, BiSS, Hiperface, Endat and SinCos , up to 32Bit/turn, 16Bit/multi.
Both the main and the optional input can be used for motor control but also for acquiring an external feedback signal placed on the application, both rotative and linear.
Light and fast.
NTT uses the latest generation of Renesas processors. A 32-bit processor with a working frequency of 100MHz and a 32-bit FPU computing capability combined with a lean and light programming of its firmware make NTT extremely reactive and performing. Performances that translated are a 10kHz PWM frequency as standard, selectable as desired from a range of 2kHz up to 20kHz. A pass band of 1600Hz guarantees the highest control performance.Put it to the test.
Integrated and certified
Integrated and certified. NTT integrates the Safe Torque-Off (STO) safety function, certified by TUV in compliance with the IEC EN 61800-5-2 standard, with stop in category 0, and with reference to the IEC61508 standard for the SIL3 level. This makes it possible to eliminate the contactor upstream of the drive, guaranteeing the maximum possible safety.
NTT has many connections. For example, it is equipped with a versatile USB2.0 for interfacing with the PC in order to perform diagnostics and calibration. But it also has an EtherNet port dedicate to PC interfacement or for setting up from remote.
Unique and super-versatile.
NTT also has an EtherNet port for today's and tomorrow's needs. Today it is an alternative to the USB port to connect the drive to a PC through the Caliper software and carry out parameterization operations.
Tomorrow will allow remote control of the drive through an external router, to communicate with industry 4.0 and IoT.
Comfort makes its way.
NTT integrates a micro USB 2.0 type port.
We chose it because it is fast, but above all because it is comfortable. Enough with serial or USB / serial converters that drive you crazy. Now to connect to Caliper, our parameterization tool, you just need a simple cable and the game is done.
Ready to use applications.
NTT240 has various working modes and numerous applications that can be activated by the software. Applications that can be used both when working with analogue references and with field buses. Electric axis, electronic cam, multi-positioner, pressure control, torque control and speed control with or without torque limit are just some of the standard applications available among the features that can be activated by the software.
Caliper, the PC interface.
Caliper is the interface software tool between PCs based on Microsoft Windows operating systems and all HDT servo drives. Designed to make the calibration of your servodrive and your motor easy and intuitive.
Display and keypad.
NTT has a 7-segment, 5-digit display and four buttons that allows both information displaying as alarms and managing most of the settings and setup of the drive.
