A16B-1100-0330 | FANUC 6058 Series 3-Axis Digital AC Servo Drive PCB — 0-B / 15-A / 0-C CNC / A16B-1100 Series

A06B-6058 — FANUC's S-Series Digital AC Servo Drives

"Main controls that run these drives are 0B, 15A and 16 Bit OC Controls." The A06B-6058 series represents FANUC's "S-Series" digital AC servo drives — the generation that brought digital servo control to machine tools using Series 0-B, 15-A, and early Series 0-C CNC systems. The A06B-6058 series spans three axis-count configurations:

• Single-axis: A20B-1003-0090 (confirmed )
• Two-axis: A16B-1200-0800 (confirmed earlier in this session)
• Three-axis: A16B-1100-0330 (this product)

Key Specifications

3-Axis Drive PCB — Machine Applications

Three axes on one drive PCB serves common CNC machine configurations:

Standard 3-axis machining centres: X, Y, Z linear axes — all three served by one A16B-1100-0330 PCB within the A06B-6058 triple-axis drive module.

CNC lathes with C-axis: Z, X, and C (spindle orientation) axes — three axes for advanced CNC turning centre capability. Consolidating three axes on one board reduces the drive cabinet's board count and simplifies the wiring between the CNC controller and the drive system.

Application Scenarios

6058 triple-axis drive PCB fault: A FANUC CNC machining centre with A06B-6058 triple-axis drives develops servo alarms simultaneously on multiple axes. The A16B-1100-0330 is identified. Repair (, ) or direct replacement restores all three-axis servo function.

S-Series legacy CNC maintenance: A production facility maintaining Series 0-B or 15-A CNC machine tools sources A16B-1100-0330 to keep the 6058 triple-axis servo system operational.

FAQ

Q1: What is the relationship between A16B-1100-0330 (3-axis), A16B-1200-0800 (2-axis), and A20B-1003-0090 (single-axis) in the 6058 family?

all three as drive cards for the 6058 series: A20B-1003-0090 for single-axis drives, A16B-1200-0800 for two-axis drives (confirmed in this session), and A16B-1100-0330 for three-axis drives. Each serves a specific axis-count variant of the A06B-6058 drive family — they are not interchangeable across axis counts.

Q2: Why is core exchange not available for A16B-1100-0330?

repair is available but no core exchange. Core exchange programmes typically apply to boards where the faulty unit's recovered components provide significant rebuild value. For the A16B-1100-0330, the repair service model (send-in for component-level repair) is the standard service route rather than board exchange.

Q3: What CNC systems ran Series 0-B with 6058 drives?

The Series 0-B is an older FANUC CNC generation predating the 0-C. Machine tools built in the mid-to-late 1980s using FANUC Series 0-B CNC control with digital servo drives used the A06B-6058 drive family. These are well-established legacy CNC machines where the A16B-1100-0330 remains the service-essential drive PCB.

Q4: Does replacing A16B-1100-0330 require servo parameter changes?

Servo parameters reside in the CNC's main SRAM. After fitting the replacement A16B-1100-0330, the CNC re-applies the existing servo parameters to all three axes automatically. Verify correct servo response at low speed on all three axes before returning to production.
