Optimizing Robot Design with Dual Encoders

Motor feedback and position measurement all in one, from HEIDENHAIN. The KCI 120 Dplus dual encoder provides motor feedback and position measurement in a single device. Installed downstream from the gear system, it enables the compensation of design-related inaccuracies in dynamic robots, such as joint elasticity, zero-position error, reversal error, and machining effects. The encoder's purely serial EnDat 2.2 interface with functional safety permits deployment in applications such as human-robot collaboration.

Secondary encoders for additional accuracy. The absolute position accuracy of your robots can also be improved by adding a high-accuracy angle encoder to each axis. Mounted downstream from the gear system, secondary encoders measure the actual position of each robot joint. We offer modular encoder solutions for this purpose, such as the HEIDENHAIN ECA 4000 with optical scanning, the AMO WMRA angle encoder system, and angle encoders from RSF. These encoders are well suited to large shaft diameters and challenging installation requirements, making them ideal as secondary encoders.
