KEBA RS‑091/A Resolver Interface Module
KEBA RS‑091/A is a revised slot‑mount resolver feedback plug‑in module for KEBA Kemro K2‑200 and K2‑400 rack‑based control systems. As the updated hardware variant of RS‑091, it is inserted into Kemro rack backplane to acquire sine‑cosine resolver analog signals from servo‑hydraulic axes and servo motors, converting analog feedback into digital position and velocity data for the main CPU. This upgraded version optimizes signal processing circuit and anti‑interference performance for heavy‑duty machinery closed‑loop motion control. Front‑panel LED indicators display module power, bus communication and resolver signal quality for rapid on‑site fault diagnosis. Parameter matching, offset calibration and diagnostic access are completed via KEBA Kemro engineering software. Widely used for injection‑molding, die‑casting and metal‑forming equipment, it delivers enhanced reliable motion feedback for Kemro rack‑style automation control solutions.
Description
KEBA RS‑091/A is a revised resolver signal acquisition plug‑in board within KEBA Kemro K2‑series rack‑mount automation ecosystem. It is the updated hardware iteration of RS‑091, featuring optimized analog front‑end circuit and improved noise suppression capability. Designed for slot‑type Kemro control racks, it connects to KEMRO‑BUS internal backplane bus and cooperates with rack CPU boards to process resolver feedback signals from hydraulic closed‑loop axes and resolver‑equipped servo motors. Adopting unified Kemro slot installation form factor, it can be installed together with CPU boards, I/O cards, communication modules and power distribution units. System integrators can insert multiple RS‑091/A boards into vacant rack slots according to machine axis quantity, flexibly expanding motion feedback channels for heavy‑load industrial machinery.
The core function of RS‑091/A focuses on resolver analog signal conditioning, filtering and digital decoding. It receives sine‑cosine analog feedback signals from motor resolvers, executes signal amplitude adjustment, noise filtering and high‑precision analog‑digital conversion, and transmits processed position and speed digital values to main controller through Kemro internal backplane bus. The revised hardware improves signal stability under strong electromagnetic interference, effectively reducing position jitter risk for hydraulic‑servo axes. Accurate resolver feedback data supports closed‑loop positioning, speed regulation and multi‑axis synchronized motion. This module is widely applied on injection‑molding machines, high‑pressure die‑casting equipment, metal forming presses and other heavy‑duty mechanical devices for servo‑hydraulic motion feedback.
Front‑panel LED status indicators intuitively show power supply condition, backplane bus communication state and real‑time resolver signal quality. Maintenance technicians can quickly identify wiring defects, shield cable faults, signal loss and channel anomalies without extra measuring instruments, shortening fault‑location time and decreasing unplanned equipment downtime. All configuration workflows including resolver parameter matching, signal offset calibration, axis assignment and fault‑diagnosis reading are finished in KEBA Kemro‑manager engineering software environment. Most practical application scenarios do not need hardware jumper modification, improving commissioning efficiency for machinery OEMs and system integrators.
The upgraded hardware circuit adopts enhanced industrial‑grade anti‑interference design, resisting electromagnetic disturbance generated by high‑power hydraulic units, frequency converters and power distribution components in complex workshop cabinet environments. Shielded resolver cables are mandatory for field wiring to maintain feedback measuring accuracy. Operators must strictly comply with official specifications for input power range, rack slot assembly rules and ambient operating temperature during installation. Improper board insertion, poor backplane contact, mismatched resolver parameters or unshielded wiring will cause position deviation or channel failure. As the revised‑version motion‑feedback plug‑in board for Kemro K2‑series control platform, KEBA RS‑091/A provides optimized and stable resolver signal‑processing capability for heavy‑duty industrial machinery automation projects.
