Ethercat
EtherCATCiA 402 ProtocolThe EtherCAT CoE protocol is a standard for data exchange in industrial automation, in jargon a high-performance "Open and realtime" fieldbus that uses the Ethernet hardware standard also used in computers but with a different operating principle in the exchange of the data packet, which is called "on the fly". Principle of operation: EtherCat CoE uses the CiA402 profile of CANopen (CoE) for data exchange and therefore, in terms of application, users who already use drives and peripherals in CANopen will find the same variables and parameters used with CanOpen. Very high performance, low cost of Ethernet technology and adoption of the CiA402 profile of CanOpen have made it in a short time the fieldbus on an ethernet basis, most widespread in the equipment proposed by the various automation actors.

Profinet
ProfiNetThe ProfiNet fieldbus option is developed in the RT (Real Time) version and in the IRT (Real Time Isochronous) version for application classes such as AC1 - AC3 - AC4.All HDT drives equipped with this fieldbus offer the same functionality. HDT - Technical specifications of the ProfiDrive protocol implemented: Application classes (AC): Technical information on ProfiNetProfiNet (short for Process Field Net) is an "Open and real-time" fieldbus based on standard Ethernet technology and compliant with IEEE802.3. suitable for industrial data management. ProfiNet - Profiles - ProfiNet TCP/IP ( No Real-time),non-deterministic profile for applications where timing is not critical which uses the standard TCP / IP and UDP / IP protocols used for parameterizations, configurations and acyclic read / write operations with which cycle times> 100 ms are achieved. ProfiDrive - the "Application Class" AC1 - Standard Drive - speed, torque and current setpoint interface.In the simplest case, the drive is controlled via a primary setpoint (for example, speed setpoint)(see Figure 16). The speed control is governed completely in the drive controller. The PLCincludes all technological functions for the automation process. The field bus is merely thetransmission medium between the automation system and the drive controller. The Cyclic DataExchange communication service is used. This type of application is used primarily in the field ofclassical drive engineering (for example, conveyor systems). A PLC is usually used as theautomation system. Clock Synchronous Operation may be used, but is typically not necessary forthis Application Class.
AC2 - Standard Drive with distributed technology controller.Application Class 2 (has not been developped by HDT) is dedicated to implementing drive applications (seeFigure 17). In this version, the automation process is broken down into many small subprocesses.The technology functions are no longer exclusively in the central PLC, but are also distributed inthe drives. The communication interface serves as the technology interface. The data that isexchanged via the bus system between the individual automation components and drivecontrollers may be individually defined. This variant assumes, however, that communication isguaranteed in all directions; that is, DO IO Data transfer should be possible also between DriveObjects (Axis). To realise applications like setpoint cascades, winders, and speed synchronism Clock Synchronous Operation should be possible. The technology functions are realised in the drive. AC3 - Single Axis positioning drive with local Motion ControlIn Application Class 3 (see Figure 18), only the technology functions for the automation processare still in the PLC. Positioning requests are stored in the Drive. A single positioning request isstarted via a command from the Controller (e.g. PLC). Interpolation and position control as wellas speed control are implemented directly in the drive. Since in this variant, all time-criticalcontrol algorithms are hidden in the drive controller, Clock Synchronous Operation is onlynecessary if complex tracking for multiple axes shall be coordinated. AC4 - Motion Control with central interpolation and speed setpoint interfaceApplication Class 4 (see Figure 19) shows the position closed loop control closed via thecommunication system. Drives for manipulator and robotic applications often require acoordinated motion sequence of several drive systems. Motion control is primarily implementedvia a central automation unit (NC). For each drive, these controllers calculate special setpointprofiles. By coordinating several drives (for example, for the XYZ axis), certain trajectories maybe implemented. In addition to the required technology functions for the automation process, theautomation system also includes the functions for interpolation and position control of the drive.Speed setpoint values and actual values as well as the position actual value are transferred viaCyclic Data Exchange. The drive controller essentially only includes the algorithms for closedloop speed control and actual position acquisition. Since the position is controlled via the bussystem, Clock Synchronous Operation is necessary and shall be very precise. Additionally, the DSC-functionality may be used to increase the rigidity and dynamic response of the control loop. |
Modbus
ModbusRTU protocolModbus is an open type serial communication protocol (RS485, but also RS232) created in 1979 to put PLCs in communication with industrial electronic devices. It is very popular and inexpensive to manage, although it does not boast great speeds, it lends itself very well to impart commands with a timing of about 20ms. Modbus allows communication between different devices connected to the same network and is often used to connect a supervisor HMI with a remote terminal unit (RTU) in supervision control and data acquisition systems (SCADA). HDT manages the Modbus RTU type protocol widely used in industrial automation and the TCP type which is very similar to Modbus RTU, but transmits the protocol packets within TCP/IP type data packets. |

Feedbacks.
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.
Maximum flexibility.
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.
CPU.
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.
STO Safety.
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.
STO
The Safe Torque-Off (STO) function of the TomCat drive consists of a redundant electrical circuit designed to bring a drive to a state of safe torque absence.
It is a function used to prevent unexpected rotation of the motor in an emergency without the obligation to disconnect the power supply. When the STO function is activated, the servodrive and the motor are in a state of functional safety or there is an impossibility of producing an active rotation of the motor shaft or if in motion it stops by inertia.
The safety circuit implemented in the drive is manufactured and certified in accordance with the IEC EN 61800-5-2 standard, with stop in category 0, and with reference to the IEC61508 standard for the SIL3 level. Stop category 0 is achieved with the immediate disconnection of the electronic components (IGBT) responsible for energizing the system, which causes an uncontrolled stop of the axis by inertia.
Advantages
It is customary in applications where there is no drive equipped with STO, to make the system safe by cutting the power by means of a suitable capacity contactor switch. Using the STO it is possible to eliminate the contactor with an economic benefit, with a saving of space in the electrical cabinet and obtaining a higher level of safety integrity.
Connectivity.
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.
Ethernet.
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.
