I. Basic Positioning

The servo axis card of the I80/B series CNC is inserted onto the JANCD-FC006 backplane and is responsible for servo axis motion control and signal interface.

Functions: Servo driver communication, position loop/velocity loop control, encoder signal processing, axis parameter management.

Compatible systems: YASNAC I80, 2000B/B CNC systems; compatible cabinets: JZNC-IRK31M, etc.

II. Core Functions

Servo axis control: Up to 4-axis servo drive control (pulse / bus type).

Encoder interface: Incremental / absolute encoder signal reception and processing.

Servo communication: Connects to Yaskawa Σ series servo drives (such as Σ-Ⅴ, Σ-Ⅶ).

Axis parameter storage: Independent management of each axis position / speed / gain parameters.

Alarm monitoring: Servo faults, encoder abnormalities, excessive following error alarms.

III. Technical Points (Disassembly / Archiving and Organization)

Version: DF9201061-B0 (mainstream).

Slot: Special slot on FC006 backplane (adjacent to FC007). Interface:

Back panel side: 50-pin flat cable (power + bus).

Servo side: CN1 (encoder), CN2 (servo command) connectors.

Number of control axes: 4 axes (configurable as 2/3/4 axes).

Signal level: 24VDC digital signal, differential encoder signal.

Operating temperature: 0°C ~ +55°C; Weight: approximately 0.6 kg.

IV. Current Status of Instructions and Materials

No separate manual: FC008 materials are integrated into the I80/B series hardware/maintenance manual.

Valid English materials:

YASNAC I80 CNC Hardware Manual (including axis card installation, terminal definitions, wiring diagrams).

YASNAC B Series Maintenance Manual (including fault diagnosis, servo parameter matching).

Supplier compiled Datasheet (including physical diagrams, version, interchange part numbers: such as JANCD-FC008-E).

V. Differences between boards of the same series

FC006: System back panel (base)

FC007: I/O adapter board

FC008: Servo axis control board

FC001: XRC robot CPU board (not CNC)
