KEBA RS‑091 Resolver Interface Module
KEBA RS‑091 is a slot‑mount resolver feedback interface module for KEBA Kemro K2‑200 and K2‑400 rack‑based control systems. It plugs into the Kemro rack backplane to collect analog sine‑cosine resolver signals from servo motors, converting raw analog feedback into digital position and velocity data for the main CPU. This module supports closed‑loop motion control for hydraulic and servo‑driven axes on heavy‑duty machinery. Front‑panel LED indicators show module power, bus status and resolver signal quality for rapid on‑site fault diagnosis. Parameter matching, signal calibration and diagnostic reading are implemented via KEBA Kemro engineering software. Widely deployed on injection molding, die‑casting and metal‑forming equipment, it delivers reliable motion feedback for rack‑style Kemro automation control solutions.
Description
KEBA RS‑091 is a dedicated resolver signal acquisition plug‑in board within KEBA Kemro K2‑series rack‑mount automation ecosystem. Designed for slot‑type Kemro control racks, it connects to the KEMRO‑BUS backplane bus and works cooperatively with rack CPU boards to process resolver feedback signals from servo or hydraulic axes equipped with resolver sensors. Different from DIN‑rail E‑series resolver modules, RS‑091 adopts rack slot installation, matching the mechanical form of other Kemro functional boards including I/O cards, communication modules and power distribution units. System integrators can insert this board into available rack slots according to machine axis quantity, realizing flexible expansion of motion feedback channels for heavy‑duty equipment.
The core function of RS‑091 is analog resolver signal conditioning and digital decoding. It receives sine‑cosine analog feedback signals from motor resolvers, carries out signal filtering, amplitude adjustment and analog‑to‑digital conversion, then transmits processed position and speed digital values to the main controller through Kemro internal backplane bus. Accurate resolver feedback data is the foundation for closed‑loop positioning, speed regulation and synchronized multi‑axis motion. This module is widely used for injection‑molding machines, high‑pressure die‑casting equipment, metal forming presses and other heavy‑load industrial machinery, providing position feedback for servo axes and hydraulic closed‑loop control axes.
Front‑panel LED status indicators intuitively display power supply condition, backplane bus communication state and resolver signal operating quality. Maintenance technicians can quickly identify wiring defects, signal loss and channel anomalies without extra measuring instruments, effectively shortening fault‑location time and reducing unplanned equipment downtime. All configuration workflows including resolver parameter matching, signal offset calibration, axis assignment and fault‑diagnosis access are completed in KEBA Kemro‑manager engineering software environment. Most practical application scenarios do not require hardware jumper modification, improving commissioning efficiency for machinery OEMs and system integrators.
The hardware circuit adopts industrial‑grade anti‑interference design, resisting electromagnetic disturbance generated by high‑power hydraulic units, frequency converters and power distribution components in complex workshop environments. Shielded resolver cables are required for field wiring to guarantee feedback signal stability and measuring precision. Operators must strictly comply with official specifications regarding power‑supply range, rack slot assembly rules and ambient operating temperature during installation. Improper board insertion, poor backplane contact or mismatched resolver parameters will trigger signal deviation or channel failure. As a professional motion‑feedback plug‑in board for Kemro K2‑series control platform, KEBA RS‑091 provides stable resolver signal‑processing capability for heavy‑duty industrial machinery automation projects.
