The FANUC A16B-3200-0512 is an internal power/wiring PCB for compatible single-axis, 200V-class FANUC βi servo amplifier modules. FANUC documentation assigns it to the SVM1-40i and later βiSV40-B 40A-class amplifier configurations.

This is a replacement circuit board, not a complete servo amplifier. Confirm the full A16B drawing number and revision printed on the original PCB, together with the amplifier model and A06B unit number, before ordering.

A16B-3200-0512 Product Information

Power-Stage Board Function

The A16B-3200-0512 forms part of the amplifier's high-current power and wiring section. In the complete SVM1-40i system, sine-wave PWM control, an FSSB interface and a dynamic-brake circuit support single-axis servo operation. The associated amplifier uses separate control electronics, so this PCB should not be described as the complete control board.

Compatibility and Revision Checks

Match the PCB number and suffix revision, amplifier nameplate, input-voltage class, current class, connectors, heat-sink layout and power devices. A16B-3200-0513 is associated with the 80A model, while A16B-3200-0515 through -0517 are 400V-class boards; these are not direct substitutes.

Testing and Installation

REACO CNC checks the label, PCB condition, terminals, power devices, insulation, DC-link section and amplifier operation on a compatible test platform where available. Disconnect incoming power and allow the DC link to discharge fully before service. Installation should be completed by qualified CNC personnel.
