Functional Features

Supports dual‑channel mirror redundancy and watchdog reset; encoder loss detection; compatibility with stepper and servo drivers; DB15 connector version for convenient field wiring; conforms to EN 61326 EMC standard; serial diagnostic interface for error vector output.

Application Scenarios

CNC machine tools, multi‑axis robotic equipment, semiconductor manufacturing equipment, precision laboratory motion platforms, high‑speed multi‑synchronized motion control systems.

Performance Parameters

Deterministic signal transmission via UBUS high‑speed backplane bus; short latency for closed‑loop motion control; signal clamping to zero when communication failure occurs.

Material Composition

FR‑4 printed circuit board, metal front panel, gold‑plated backplane connector, DB15 female connectors, industrial‑grade buffer IC and servo IC chips.

Structural Characteristics

Standard 3U Eurocard structure; single‑slot installation, occupies two slots when equipped with Option‑1A expansion module; captive screws for rack fixation; DB connectors mounted on front panel for breakout connection.

Working Principle

Receives digital motion instruction from UMAC CPU through UBUS backplane bus; converts digital setpoint into ±10 V analog command signal or pulse‑direction signal; collects encoder feedback signal from motor, sends feedback data back to main controller to realize closed‑loop position, velocity and torque control.

Installation Requirements

Install into UMAC 3U rack backplane slot; complete ESD protection operation before installation; match jumper settings according to drive signal mode; DB15 signal cables shall keep distance from high‑power power cables to avoid electromagnetic interference.

Usage Notes

Do not hot‑swap under power‑on state; operating environment must avoid condensation; confirm jumper configuration matches servo/stepper mode; regularly inspect DB connector locking state; ESD grounding must be reliable during maintenance; do not exceed rack specified backplane power load.
