The FANUC A13B-0198-B122 is an integrated CNC display and control unit used in compatible FANUC iS-series configurations, commonly associated with Series 31i and 32i systems. It combines a 15-inch color LCD with CNC control electronics and is not simply a replacement screen.

Specialist parts references identify an A20B-8101-0046 main board, a Sharp LQ-series LCD and an FSSB servo interface in documented assemblies. Internal revisions and options can vary, so the complete label and fitted hardware must be checked.

CNC Display and Control Function

The A13B-0198-B122 displays CNC position, program, offset, parameter, diagnostic and alarm information. Its internal electronics form part of the CNC configuration and work with installed software, PMC logic, servo and spindle hardware, I/O and operator-panel components.

Where fitted, FSSB provides the FANUC Serial Servo Bus connection between CNC servo-control hardware and compatible servo amplifiers. FSSB is different from HSSB, which is used mainly for high-speed CNC-to-PC communication.

Complete Unit and LCD Clarification

Search results include complete A13B-0198-B122 units and aftermarket products marked “A13B-0198-B122-LCD.” They are not equivalent. The complete FANUC assembly contains control hardware in addition to the LCD, while an LCD replacement normally supplies only a screen or conversion kit.

Confirm whether the product includes the enclosure, main board, power components, LCD, interface boards, fans and cables. Photographs and internal PCB numbers should match the original unit.

Compatibility Note

Before ordering, please verify:

• Complete A13B-0198-B122 number
• FANUC CNC series, model and software edition
• Machine manufacturer, model and serial number
• Main-board number, PCB revision and installed memory
• LCD-panel number and connector arrangement
• Touch or non-touch configuration
• FSSB and other installed interface hardware
• Power, display and operator-panel connections
• CNC options, PMC ladder and machine data
• Existing alarms and failure symptoms

Compatibility cannot be established from the 31i or 32i family name alone. A13B-0198-B121, B123, B211 and other similar A13B-0198 units are not confirmed substitutes unless their hardware, display and system configurations match.

Replacement and Data Protection

Replacement may be appropriate for confirmed startup, display, video, backlight, internal control or physical-damage faults. However, display problems may originate from the LCD, inverter or power circuitry, while FSSB alarms can result from optical cables, servo amplifiers or configuration errors.

Before removal, back up accessible SRAM data, CNC parameters, programs, offsets, macro variables, pitch-error data, PMC files and machine-builder information. Installation may require restoration of the original software, options and data by a qualified technician.

Common Use Cases

• Replacement of a failed A13B-0198-B122 unit
• Repair of a compatible FANUC 31i/32i iS control
• Restoration of a 15-inch CNC operator display
• Troubleshooting CNC or FSSB interface hardware
• Preparation of a tested system spare
