1 BASICS NCT 200 Control series The evolution of electronics, faster microprocessors, internet, high-speed networks, mobile world, the endless range of PC peripheries and services turned the conservative industrial electronics upside down. These days a successful CNC is unthinkable without ETHERNET connection, high capacity memory, or a PENDRIVE for saving part programs or without any cursor device (mouse, touchpad, trackball, touchscreen).
BASICS NCT 201 hardware The NCT 201 is the first member of NCT 200 series control family. The industrial CNC CPU of the NCT 201 is located behind a large LCD monitor and provide a single unit for easy installation. This hardware includes the complete CNC software together with integrated PLC. All peripheries that control the machine tool connect to CNC by EtherCAT channel that is a worldwide standard these days.
3 BASICS Touchscreen User-friendly The user-friendly interface (HMI) is the most important advantage of a touchscreen. Data input is done by a virtual keyboard “painted” on the touchscreen. The keyboard picture only appears and takes up screen space when data input is possible. Adapting other languages is not a problem due to the virtual keyboard; user can select the language of keyboard easily. The size and location of buttons provides convenient data input.
HANDLING, PROGRAMMING Windows in screen Create your own user interface that offers the most convenient operation! The reason for application of window structure is user interface created in WINDOWS operation system. Each window is an individual panel whether or not contains data input or other control options. User can locate panels anywhere in the screen in arbitrary disposition. Panels can be resized optionally. The screen composed by user can be saved or also frozen.
5 MORE CHANNELS, HIGH SPEED MACHINING More channels One of the most important advantages of the NCT 200 controls is the multi-channel structure. It means several logical CNC controls in one physical unit. Each channel is an individual CNC control that executes its own technological program by continuous coordination with the other channels. The number of channels limited by only the speed of CPU, that can be at most 8 in the present system.
PROBING IN MACHINE TOOL Measuring in machine tool Tool or workpiece touch probe from any manufacturer can be connected to NCT 200 controls by ETP card. MES software integrated in control manages high variety of touching, measuring functions, the DIGI program package touches control path and complex surfaces. Some manufacturers (RENISHAW, M&H) offer software packages for their touch probes. These MACRO programs can also be installed in NCT controls.
NCT SYNCHRONOUS AND ASYNCHRONOUS SERVO DRIVES AND SERVO MOTORS 7 NCT servo drives The NCT servo drives are complete EtherCAT peripheries. They are connected to NCT 200 control central unit (EHU) by one EtherCAT bus. Moving commands are received and also absolute position transmitted to CNC software by using this wide-frequency channel. NCT servo drives are developed especially for machine tool applications.
NCT SYNCHRONOUS AND ASYNCHRONOUS SERVO DRIVES AND SERVO MOTORS Synchronous servo motors NCT synchronous servo motors are available in 1 Nm -75 Nm torque range with three flange sizes. The shaft design and connecting main dimensions are compatible with similar sized motors of several Japanese manufacturers. Asynchronous spindle motors High-speed asynchronous motors are primarily used for driving spindles of machine tools, and are available with throughbored shaft and up to 15000-rpm speed.
9 PLC PLC The PLC integrated in the NCT 200 controls can be programmed in popular LADDER system, providing effective error detection for maintenance and repairing personnel. Ladder displayed in the PLC window and the “green flow” represents logical states and processes during operation. High-level language (PYTHON) is available for PLC programmers, machine tool builders to create their own user interface.
COMMUNICATION, SOFTWARE UPDATE, SAFETY ETHERNET ETHERNET connection is a basic accessory of each part of NCT 200 control series. It can be connected into any WINDOWS network (TCP/IP protocol, 100 Mbit/sec speed) without any external software. After that a part program can be loaded easily into the HDD of the control, or it can be assigned to run and execute without loading it into the memory of control.
11 DIAGNOSTICS Logbook Creating Logs, sending log file The inspection module of NCT inspects and records every event and creates an event history! The NCT 200 controls save each important event in a log file. In case of any malfunction during the operation of the unit, whether or not it was caused by error of servo system, operator error, or error detected by PLC. This log file can be sent to the NCT customer service center by email. Control will be an open book for NCT professionals by log life.
DIAGNOSTICS Oscilloscope Oscilloscope with digital memory integrated in the control is essential for accurate setting of servo drives. The signals displayed graphically in relation to time can be set in 4 channels simultaneously. These can be signals of servo system, PLC IO lines or state of internal flag bits or value of variables. Saving starts when START button pressed is independent from fulfilling triggering conditions.
13 SERVICES FOR INCREASED ACCURACY OF MACHINE TOOLS Reversal error This is the basic compensation for each machine tool control. Most of the time the movment of a slide is generated by the rotation of a servomotor. When reversing direction, the motor rotates for a short interval as the slide does not move yet, because of the backlash and flexibility of mechanical parts that transform rotational motion into straight-line or rotational motion.
SERVICES FOR INCREASED ACCURACY OF MACHINE TOOLS Stick slip The phenomenon of stick slip can occur on wide flat box ways where the stick slip compensation can be used effectively. The slide movement can be initiated by a “kick start” through a parameter with preset time and speed impulse value, and by immediately returning the speed to the normal value as soon as the slide started to move. This eliminates excess speed caused by increasing speed command generated by position control loop for stick slip.
15 EXAMPLES FOR APPLICATION NCT 201 on machine tools Offering professional and also efficient CNC package for machine tool manufacturers and machine rebuild personnel has always been an important aspect in development of NCT CNC controls. NCT 200 series are the most developed products also in this aspect.
