ENGEL ElektroMotoren controller, German ENGEL ElektroMotoren model, ENGEL ElektroMotoren price

ENGEL ElektroMotoren controllers convert predetermined control schemes and planning instructions into desired mechanical motion under complex conditions, achieving precise position, speed, acceleration, 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 forward/reverse rotation or intermittent start-stop cycles. Motion control applications in robotics and CNC machine tools are more complex than those in specialized machinery, as the latter involve simpler motion forms, often referred to as General Motion Control (GMC).

ENGEL ElektroMotoren 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. An 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 lettering 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 circuit; for 24-36V, use 60A/50V MOS power transistors for control, with output current 5A per circuit. Users can select the number of controller circuits 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 uses resistor current limiting, which results in high resistor power dissipation; it is recommended to connect one 1/4W metal film resistor in series with every 4 LEDs for uniform heat distribution, offering the most stable and reliable performance. The other method uses RC series current limiting, where most voltage drop occurs across the capacitor, resulting in low resistor power dissipation; this 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 employ resistor current limiting. LEDs typically consume 5W per meter per circuit, with three-color LEDs consuming 15W per meter. Common gradient controllers include NE112K for controlling DC loads up to 1200W, and NE103D for AC loads up to 4500W or DC loads up to 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 tubes and LEDs have different luminous distribution characteristics, so different load types must not be mixed in the same circuit. 3) Low-voltage serial controllers: Low-voltage LED serial controllers feature high channel counts, 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. The NE040S controller model can be selected, with a maximum capacity of 4096KBit. If the load consists of 512-unit 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.

ENGEL ElektroMotoren controller functions

1) Motion planning function: This establishes reference values for motion speed and position. Suitable 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 quantities 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 yield excellent dynamic characteristics. For rapid positioning systems with high acceleration and short travel, 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 growth of the engraving market, particularly 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 demands motion controllers with 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 can make one axis follow a function determined by the motion of other axes, or follow the combined speed of two other axes at a set ratio. Electronic cam functions allow cam profiles to be changed via programming, eliminating the need to grind mechanical cams and greatly simplifying processing. 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 effectively used in laser engraving applications with Googol Technology's general motion controllers. 5) Probe signal latching function: This latches the moment a probe signal is generated and the positions of all motion axes. Accuracy depends solely on hardware circuits, unaffected by software or system inertia, making it valuable in the CCM measurement industry. Furthermore, an increasing number of 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, reconstructing a special-purpose dedicated motion controller without altering the control system's structural design.

ENGEL ElektroMotoren 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 themselves for more precise control. An actuator, such as a hydraulic pump, cylinder, linear actuator, or motor, outputs the motion. A feedback sensor, such as an optical 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. Various methods calculate motion trajectories, usually based on velocity profiles such as triangular, trapezoidal, or S-shaped velocity curves. 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 disks 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.
