Alpha Servo SVM1-130 Power PCB for Single-Axis Drive Repair

Main Description

The FANUC A16B-2202-0790 is an Alpha servo SVM1-130 power PCB used in a single-axis drive context.

It is listed as a servo board / power PCB with 24 VDC coil voltage and 1 LED indicator, which places it squarely in the Alpha servo amplifier section rather than in the CNC main-board or operator-panel categories.

In real service work, a board like this belongs to the amplifier-side hardware that supports the single-axis Alpha servo arrangement.

It is most valuable when the amplifier remains repairable and the correct board is needed to restore the original drive structure instead of replacing the complete amplifier stack. 

Because it is tied to SVM1-130, exact matching matters more than visual similarity.

Parameter Table

Applications

The A16B-2202-0790 is best suited to Alpha-series single-axis servo amplifier repair, especially where the machine uses an SVM1-130 configuration and the original drive hardware is still worth maintaining.

It fits applications such as servo board replacement, power-board refurbishment, drive-repair inventory, and legacy Alpha servo support in CNC service environments.

It is also appropriate for repair shops that handle board exchange and for users who want to restore the original single-axis amplifier arrangement instead of replacing the entire drive section.

In those cases, the correct power board can be the most direct path back to stable drive operation.

Replacement Guide

Before replacing the A16B-2202-0790, the drive section should be inspected as a whole.

That includes checking whether the fault is in the power board, the surrounding servo amplifier hardware, or related wiring and feedback paths. 

Since this model is tied to a single-axis Alpha SVM1-130 layout, board replacement should be based on amplifier-level diagnosis rather than on a generic board swap.

After installation, technicians should verify stable startup, proper indicator behavior, and consistent single-axis drive response under normal operating conditions.

Those post-replacement checks are especially important for servo power boards because successful repair depends on both electrical compatibility and stable amplifier behavior in use.

FAQ

Q1: What is A16B-2202-0790?
It is an Alpha servo SVM1-130 power PCB used as a single-axis board in the FANUC Alpha servo amplifier environment.

Q2: Is this a main CNC control board?
No. It belongs to the servo amplifier section, where it functions as a servo/power board rather than as the central CNC processor board.

Q3: What does the single-axis designation mean?
It means the board is intended for a one-axis amplifier layout. That matters because axis configuration affects board compatibility and the way the amplifier is structured.

Q4: Why does the 24 VDC coil specification matter?
It helps identify the board’s operating context inside the amplifier assembly and is one of the listed details used to distinguish this model from other Alpha-series boards.

Q5: What should be checked before buying or replacing this board?
Confirm the exact part number, verify the SVM1-130 application, inspect the existing board and amplifier condition, and make sure the fault belongs to the board section rather than to the broader drive hardware.
