Kollmorgen’s new SFD-M high-resolution encoder offers multi-turn absolute feedback at zero incremental cost | RoboticsTomorrow

Kollmorgen servo motors are now on hand with our fourth-skills SFD-M trim suggestions tool. Supplied at no extra price over Kollmorgen’s earlier SFD objects, this encoder affords four events greater positioning accuracy and uses vitality-harvesting skills to trace absolute multi-flip positioning even when the machine is powered off.

Kollmorgen, a global chief in circulation administration and automation programs, these days launched the contemporary SFD-M (Tremendous Feedback Tool, Multi-Flip). It enables machine builders to retain out high-possibility multi-flip suggestions with absolute positioning recordsdata on hand at machine startup.

Designed to work with AKDTM and AKD2G drives, the SFD-M absolute multi-flip encoder would possibly additionally be integrated into Kollmorgen housed servo motors at no extra price compared to the SFD-3 single-flip absolute encoder, providing multi-flip performance, four events greater positioning accuracy and fifty events lower EMF noise.

Associated third-celebration encoders reach with a top class label. With the SFD-M, possibilities can carry out mighty savings in machine designs that manufacture on the superb levels of precision, efficiency and effectiveness.

Absolute multi-flip positioning for proper, productive circulation

The SFD-M measures the role of the rotor shaft throughout each 360º rotation without requiring reference to a rental role, and it registers the total possibility of rotations the shaft has made in both route.

This absolute multi-flip positioning functionality is great when proper monitoring of role is required over neat rotational distances, reminiscent of in machine instrument positioning, packaging machines, cloth facing, satellite tv for pc monitoring and heaps various applications.

Additionally, the SFD-M maintains absolute positioning recordsdata in proper time even when the machine is powered down, laying aside the need for time-drinking homing sequences upon startup.

Energy-harvesting skills for battery-free operation

Absolute multi-flip encoders from various suppliers in overall require a battery to retain positioning recordsdata when the machine is powered down or all the arrangement in which by a vitality failure. These exterior batteries require change and is susceptible to be subject to failure. Totally different alternate choices consume mechanical tools trains, that are noisy, backlash-susceptible and add size to the motor.

The contemporary Kollmorgen SFD-M eliminates these issues, as every other the usage of vitality-harvesting skills to reliably retain positioning recordsdata and not utilizing a need for batteries or tools trains. Battery-free operation eliminates repairs issues while additionally supporting efforts to lower the consumption of pure property and lower spoil.

Distinctive performance at an mighty price

The SFD-M is extremely correct, providing these key specs:

Resolution

o 24 bits per revolution

o 16,777,216 counts per revolution

o 0.0772 arc-sec per count

Multi-flip absolute differ

o 16 bits = 65,536 motor revolutions

Accuracy

o +/- 1 arc-min conventional at 25ºC

o +/- 3 arc-min worst case

“Our contemporary SFD-M encoder affords multi-flip absolute functionality with mighty role accuracy and possibility at zero extra price over Kollmorgen motors with single-flip encoders,” talked about Chris Cooper, Kollmorgen’s Senior Director of World Product Management.

“That’s a substantial earnings for precision and productiveness at a savings of quite loads of of bucks per motor and potentially several thousand dollars in a complicated, multi-axis machine. Single motor-to-pressure cable skills with auto pressure setup further lowers complete charges. We’re very proud to offer all of these advantages to our possibilities as an integral phase of Kollmorgen’s trade-leading servo programs.”
