cab Produkttechnik controller German cab Produkttechnik model cab Produkttechnik price

cab Produkttechnik controllers convert predetermined control schemes and planning instructions into desired mechanical motion under complex conditions, achieving precise position, speed, acceleration, and torque or force control. A motion controller is a dedicated controller for managing motor operation modes: for example, a motor drives an object upward to a specified position via a limit switch controlling an AC contactor, then moves downward; or a time relay controls the motor's forward/reverse rotation or intermittent start-stop cycles. Motion control applications in robotics and CNC machine tools are more complex than in specialized machinery, as the latter involves simpler motion forms, often referred to as General Motion Control (GMC).

cab Produkttechnik controller types

1) Low-voltage LED product controllers: Low-voltage LED products are generally designed for 12V-36V, with 3-6 LEDs per circuit connected in series, using resistors for voltage drop and current limiting, keeping each circuit current below 20mA. A LED product consists of multiple circuits of LEDs. Advantages include low voltage, simple structure, and ease of design; disadvantages include high current at large scales, requiring low-voltage switching power supplies. Due to these limitations, low-voltage systems cannot transmit power over long distances and are limited to compact products such as sign text and small patterns. Based on these characteristics, controller design specifications are: for 12V, use 75A/30V MOS power transistors for control, with output current 8A per channel; for 24-36V, use 60A/50V MOS power transistors for control, with output current 5A per channel. Users can select the number of channels based on these specifications; for jumping effects, choose the NE20 low-voltage series, and for gradient effects, choose the NE10 low-voltage series controller. Note that LEDs must use common anode (+) connection, with the controller switching the cathode (-); the controller does not include a low-voltage power supply. 2) High-voltage LED product controllers: High-voltage LED products are designed for AC/DC 220V voltage, with 36-48 LEDs per circuit connected in series, and each circuit current below 20mA. There are two current-limiting methods: one is resistor current limiting, which causes significant resistor power dissipation; it is recommended to connect one 1/4W metal film resistor for every 4 LEDs in series to distribute heat evenly, ensuring stability and reliability. The other is RC series current limiting, where most voltage drop occurs across the capacitor, resulting in low resistor power dissipation; this method is only suitable for steady-on states. If flashing occurs, capacitor energy storage can double the voltage, easily damaging the LEDs. All LEDs used with controllers must use resistor current limiting. LEDs are typically one meter per circuit, with power 5W, and three-color power 15W per meter. Common gradient controllers include NE112K for controlling DC 1200W, NE103D for AC loads 4500W and DC loads 1500W. Use NE112K if there are many flashing tube units, or NE103D if only overall flashing is required. When using gradient modes, ensure load matching; neon lights and LEDs have different luminous distribution characteristics, and different load types should not be mixed in the same circuit. 3) Low-voltage serial controllers: Low-voltage LED product serial controllers feature a high number of control channels, using serial signal transmission for control. Generally, controlling 512 units requires only 4 control lines. Serial LED controllers require registers on the LED light source board. Users can select the NE040S controller model, which has a maximum capacity of 4096KBit. If the load is 512 units of LEDs, it can achieve up to 8192 frames. Additionally, controllers are used in the safety industry to monitor gas levels within operating zones using detectors.

cab Produkttechnik controller functions

1) Motion planning function: This establishes the reference values for motion speed and position. Appropriate reference values not only improve trajectory accuracy but also reduce requirements for the drive system and mechanical transmission components. General motion controllers typically provide motion planning methods that limit values affecting dynamic trajectory accuracy, such as jerk, acceleration, and speed, allowing users to call corresponding functions directly. Motion planning with acceleration limits produces trapezoidal velocity profiles; motion planning with jerk limits produces S-shaped velocity profiles. Generally, for CNC machine tools, motion planning methods limiting acceleration and speed reference values provide excellent dynamic characteristics. For rapid positioning systems with high acceleration and short strokes, strict requirements on positioning time and overshoot often necessitate motion planning methods with continuous higher-order derivatives. 2) Multi-axis interpolation and continuous interpolation functions: The multi-axis interpolation function provided by general motion controllers is widely used in the CNC machinery industry. In recent years, the rapid development of the engraving market, especially mold engraving machines, has driven the development of continuous interpolation functions in motion controllers. Mold engraving involves processing numerous short line segments, requiring minimal speed fluctuation between segments and smooth transitions at speed change points. This requires motion controllers to have look-ahead speed and continuous interpolation capabilities. Googol Technology's continuous interpolation motion controller, designed specifically for small segment processing, has been successfully applied in mold engraving, laser engraving, and planar cutting. 3) Electronic gear and electronic cam functions: Electronic gears and cams significantly simplify mechanical design and enable functions difficult to achieve with mechanical gears and cams. Electronic gears allow multiple motion axes to move synchronously according to a set gear ratio, making them ideal for fixed-length shearing and shaftless register printing. Additionally, electronic gear functions allow one axis to follow a function determined by the motion of other axes, or to follow the combined speed of two other axes at a set ratio. Electronic cam functions allow cam profiles to be changed via programming without grinding mechanical cams, greatly simplifying processing techniques. This function is well-suited for quenching of mechanical cams, irregular glass cutting, and all-electric spring driving. 4) Compare output function: During motion, when the position reaches a set coordinate point, the motion controller outputs one or more digital signals without affecting the motion process. For example, in AOI flying probe inspection, the compare output function triggers CCD high-speed imaging at set positions without interrupting motion, significantly improving efficiency and image quality. This function is also widely used in laser engraving applications with Googol Technology's general motion controllers. 5) Probe signal latching function: This function latches the moment a probe signal is generated and the positions of all motion axes. Accuracy depends only on hardware circuits, unaffected by software or system inertia, making it ideal for CCM measurement applications. Additionally, more OEM manufacturers wish to integrate their extensive industry application experience into motion control systems, customizing motion controller functions for specific applications and control objects. Googol Technology has developed a general motion controller application development platform, providing a truly object-oriented open control structure and system reconfiguration capability. Users can load custom control algorithms into the motion controller's memory, creating specialized motion controllers without altering the control system's structural design.

cab Produkttechnik controller composition

A motion controller generates trajectory points (desired output) and closes the position feedback loop. Many controllers can also close a velocity loop internally. A drive or amplifier converts the motion controller's control signals (typically speed or torque signals) into higher-power current or voltage signals. More advanced intelligent drives can close position and velocity loops internally for more precise control. An actuator, such as a hydraulic pump, cylinder, linear actuator, or motor, outputs the motion. A feedback sensor, such as a photoelectric encoder, resolver, or Hall effect device, feeds back the actuator's position to the position controller to close the position control loop. Numerous mechanical components convert the actuator's motion into the desired form, including gearboxes, shafts, ball screws, timing belts, couplings, and linear and rotary bearings. Typically, a motion control system's functions include speed control and point-to-point control. There are many methods to calculate a motion trajectory, usually based on a motion velocity profile such as triangular, trapezoidal, or S-shaped velocity profiles. Examples include electronic gears (or electronic cams), where the slave axis position mechanically follows the master axis position. A simple example is a system with two turntables rotating at a given relative angle. Electronic cams are more complex than electronic gears, allowing the follow relationship between master and slave axes to be defined by a function. This curve can be nonlinear but must be functional.
