German INDUcoder encoder INDUcoder model INDUcoder price

The INDUcoder encoder uses a photoelectric pulse generator synchronized with the spindle, transmitting synchronization through gears on the intermediate shaft at a 1:1 ratio. There is no direct mechanical connection between the rotation of the CNC lathe spindle and the feed motion. To machine threads, the number of pulses given to the feed servo motor must correspond to the spindle speed; the spindle pulse generator serves to link spindle rotation with feed motion. A thread is a continuous series of ridges and grooves of identical profile formed along a helix on a cylindrical or conical surface. Threads formed on cylindrical surfaces are called cylindrical threads, and threads formed on conical surfaces are called conical threads. Threads formed on the outer surface of a body of revolution are called external threads, and threads formed on the inner surface are called internal threads. There are many methods for machining threads. When cutting threads on a lathe, the lathe clamps the cylindrical workpiece with a three-jaw chuck and drives it to rotate at a constant speed. The lathe feed mechanism drives the turning tool (standard threading tool) to move in a straight line at a constant speed along the cylinder axis. The tool tip cuts triangular grooves into the workpiece surface to form triangular threads. During thread machining, there is a trajectory start point (A point, i.e., the tool engagement point) and a trajectory end point (B point, i.e., the tool retraction point). In the thread machining trajectory, sufficient acceleration tool engagement distance δ and deceleration tool retraction distance δˊ are provided to ensure thread quality and eliminate pitch errors caused by servo lag.

INDUcoder encoder installation and use

Mechanical installation and use of absolute rotary encoders: Mechanical installation of absolute rotary encoders includes various forms such as high-speed end installation, low-speed end installation, and auxiliary mechanical device installation. High-speed end installation: Installed at the drive motor shaft end (or via gear coupling). The advantage of this method is high resolution. Since multi-turn encoders have 4096 turns, and the motor rotation falls within this range, the full range can be utilized to improve resolution. The disadvantage is gear backlash error during forward and reverse motion after passing through reduction gears. It is generally used for unidirectional high-precision positioning control, such as roll gap control in steel rolling. Additionally, when the encoder is directly installed on the high-speed end, motor vibration must be minimal; otherwise, the encoder is easily damaged. Low-speed end installation: Installed after the reduction gear, such as at the shaft end of a hoist wire rope drum or the last stage of the reduction gear shaft. This method eliminates gear backlash, provides more direct measurement, and offers higher accuracy. This method is generally used for long-distance positioning measurements, such as in various lifting equipment and feeding cart positioning. Auxiliary mechanical installation: Common methods include rack and pinion, chain and belt, friction wheels, and rope winding mechanisms.

INDUcoder encoder component differences

From single-turn absolute encoders to multi-turn absolute encoders. An absolute rotary single-turn absolute encoder measures the tracks on the optical code disk during rotation to obtain a unique code. When rotation exceeds 360 degrees, the code returns to the origin, which violates the principle of unique absolute encoding. Such encoding can only be used for measurements within a rotation range of 360 degrees and is called a single-turn absolute encoder. To measure rotation beyond a 360 degree range, multi-turn absolute encoders are used. Encoder production applies clockwork gear mechanics. When the central code disk rotates, it drives another set of code disks (or multiple sets of gears and code disks) through gear transmission. Based on single-turn encoding, turn count encoding is added to expand the encoder's measurement range. Such absolute encoders are called multi-turn absolute encoders. They also determine encoding by mechanical position, ensuring each position code is unique and non-repeating without the need for memory. Another advantage of multi-turn encoders is that due to the large measurement range, there is often considerable margin. Thus, during installation, it is not necessary to painstakingly find the zero point; any intermediate position can serve as the starting point, greatly simplifying installation and commissioning.

INDUcoder encoder applications

This encoder uses relative counting for position measurement. Before operation, signals such as the pulse counts corresponding to speed change points, leveling points, and braking stop points are stored in respective memory units via programming. During elevator operation, the rotary encoder detects and software calculates the following signals in real time: elevator floor position, speed change point position, and leveling point position, thereby performing floor counting and issuing speed change and leveling signals.
