The FANUC A06B-6116-H022#H560 is a 200V-class αCi Series spindle amplifier module, identified by FANUC as model SPMC-22i. It controls the speed and torque of a compatible FANUC spindle motor within an αi CNC drive system.

The module has a documented rated output current of 95A and uses sine-wave PWM control with an IGBT bridge. It operates with a compatible FANUC power supply module, CNC interface, spindle motor and feedback configuration; it is not a standalone variable-frequency drive.

SPMC-22i Spindle Control Function

The SPMC-22i receives spindle commands from the FANUC CNC and regulates motor current, speed and torque through its IGBT power stage. The amplifier works as part of a shared αi drive arrangement and requires the correctly sized power supply module, DC-link connection and spindle motor parameters.

#H560 and Related Model Checks

The complete A06B-6116-H022#H560 number should be matched. A06B-6116-H015#H560 is the lower-output SPMC-15i model, while similarly numbered A06B-6111 and A06B-6112 units belong to different spindle-amplifier specifications. Matching only “H022” is not sufficient.

Replacement and Installation Notes

Confirm the complete amplifier nameplate, #H560 suffix, spindle motor model, power supply module, feedback detector, connectors, CNC series and spindle parameters. Back up parameters and diagnostic data before replacement. Qualified personnel must isolate the incoming supply and wait for the DC-link voltage to discharge before removing the module.
