AKD2G<\/strong><\/a> drives, the new encoder option provides absolute multi-turn position feedback. The absolute encoder achieves actual angular position per revolution in 24-bit resolution. This capability results in high-precision sensing throughout each 360\u00ba rotation, with 16,777,216 counts per revolution at 0.0772 arc-sec per count. Accuracy is +\/- 1 arc-min, typical at 25\u00baC.<\/p>\n\n\n\nRegistering the number of shaft rotations in either direction, the multi-turn resolution capability is provided at 16 bits, and can track up to 65,536 motor revolutions. Registering absolute multi-turn position, even when the system is powered off, allows machine end users to achieve a rapid system start up, which is especially useful for machines that involve moves over longer distances. This approach eliminates the need for time-consuming homing sequences when the machine is powered on, optimising productivity and reducing power consumption.<\/p>\n\n\n\n
As a result of this performance, the new SFD-M encoder is well suited for applications such as machine tool positioning, packaging machines, material handling, satellite tracking, and other applications that require precision position sensing over longer distances.<\/p>\n\n\n\n
The absolute multi-turn capability is provided at the same price as Kollmorgen’s SFD-3 single-turn absolute encoder. The new device also achieves a significant cost saving compared to integrating a third-party sensor. The new Kollmorgen SFD-M encoder is integrated directly into Kollmorgen’s AKM and AKM2G housed servo motors, saving space and maintaining a low footprint. The design also achieves low electrical noise, up to 50 times lower than previous designs.<\/p>\n\n\n\n
The encoder’s battery-free design also optimises reliability and minimises maintenance. This is achieved with energy-harvesting technology, removing the challenge of battery failure and replacement, common to other multi-turn encoder designs that use batteries to retain position information after powering down. The battery-free design also reduces size and creates a more sustainable design alternative. The SFD-M encoder’s approach to power supply when mains power is off is also preferable to integrating mechanical gears, which are backlash-prone and add size \u2013 and audible noise.<\/p>\n\n\n\n
