Key Questions From Buyers (FAQs)

What is the difference between A06B-6140-H026 and spindle amplifiers like A06B-6141-H026?

The A06B-6140-H026 is designed to drive servo motors (αiS series) for axis control, whereas A06B-6141-H026 is built specifically for spindle motor control (αiSP series). They are not interchangeable.

What alarms does this amplifier typically trigger if there’s a fault?

Here are common alarms based on the fanuc drive alarm list:

Alarm Code	Meaning
AL-01	Overcurrent
AL-04	Fan failure
AL-06	Braking circuit issue
AL-12	FSSB communication failure
AL-30	Thermal overload

Fast diagnostics via the LED panel and CNC system allow for rapid issue resolution.

Is this amplifier compatible with older FANUC controls?

Only if the control supports FSSB fiber optic communication. Analog and SERCOS-based systems will not support this unit without interface changes.

Can I use this to retrofit my old axis amplifier?

Yes—if your servo motor is αiS series and your control uses FSSB, this unit is often used in retrofit applications. Always verify current ratings and motor specs.
